Notes

Obviously, you know this site is not the Chromium official website. As a regular user (not an expert), I created it because I did not find a simple way to download good releases. I try to keep it as safe and fast as possible! ;) This is absolutely a non-profit site. Please, read the #privacy-policy (on the right-hand side).

In short:
  • The official website is development oriented. Users are invited to download Google Chrome.
  • The official download page gives to users only "Nightly" builds (using the official Snapshots repository).
  • This site gives to users a choice of builds: "Nightly" (also on its simplest download page), LKCR, stable and portable builds.

All downloads are from reliable sources only:
Explanation...

1. Project

Chromium exists since 2008. It is the free and open-source project (#features) behind the famous Google Chrome browser. Intrinsically, Chromium is a Google project maintained by many authors (developers, engineers, graphic designers, security researchers...) from Google, Opera, Yandex, Samsung, Intel, Facebook, Hewlett-Packard... and external contributors. Chromium is not designed by Google!

2. Stable Chromium version

Officially, Chromium does not have a stable release. The official developers (aka The Chromium Authors) do not release it to end users. So it is continually in development. Google Chrome is the stable release... but is not open-source.

In fact, Chromium has a stable version. ^^
Example: The current stable version on #linux is 63.0.3239.108. In this version, there are 108 patches which correct many issues (bugs, feature requests, enhancements...). Because Chromium is open-source (#source-code), anybody can build it. You must be a developer to do this. Just get the current stable version (63.0.3239.108) from the official Git repository and compile it!

The stable version is used in:

3. Development

Basically, Chromium has few versions every day, but you can stick with a version for about a month before you need to upgrade.

dev
A DEV build (known as Snapshot, "Nightly" or "Raw" build) is compile of the Chromium code whenever there are submitted code changes. A snapshot build will be created as long as the code compiles successfully. Its binary files are stored in the Snapshots repository of Google Storage. This build is really just development tool for checking whether issues are fixed in the latest Chromium code. It can be buggy and unstable.

lkcr
A LKCR build does at least provide some level of guarantee that the particular revision actually should build, which is good for third-party builds for not wasting time on potentially uncompilable builds. As a result, LKCR usually trails the dev trunk by a few revisions (commits).

If building straight off dev, it can be a guess whether a build will compile or not, so a third-party builder could be wasting processor cycles that could otherwise go to a known compilable build (LKCR).

lkgr
Each snapshot build is then run through the automated tests. If that snapshot build successfully passes the automated tests, it is considered as a good build: LKGR (Last Known Good Revision)... and can become potentially a stable build.

Note LKGR builds were stored in the Continuous repository until Friday, 18 Mar 2016 (1 year ago). The Chromium team has removed few LKGR builders (407399, 576253 and chromium-dev) but other ones still work (latest commit, latest builds). Finally, there is no LKGR binary shared by the Chromium team... but any developer can re-compile it! ^^

stable
A stable build is a LKCR build tested and improved by the Chromium team.

In resume:
  • dev: Untested and may be unstable version, downloadable on the official site and my alternative webpage.
  • LKCR: Similar to "dev" version but for third-party build.
  • stable: The most stable version.

4. Finally

Except for stable versions, the developers use the official Snapshots repository to re-compile their builds.

So I give you the opportunity to download only nice Chromium releases ;)

Features

Chromium vs Google Chrome.

Chromium browser has:
  • only open-source licenses (BSD license, MIT license, LGPL, MS-PL and MPL/GPL/LGPL tri-licensed code) plus unlicensed files. It is a FOSS project. A full list of software developed by third parties is available within the browser at chrome://credits
  • a blue-colored logo
  • the similar sandbox as Google Chrome (For info, Firefox also uses it)
  • the similar user interface and settings as Google Chrome
  • the similar support for Extensions, Themes and Web Apps as Google Chrome
  • the similar user agent as Google Chrome
  • the built-in Chrome PDF Viewer (known as PDFium), on Windows OS
  • the built-in Chromoting Viewer (To use it, you need to first install the Chrome Remote Desktop app)
  • the built-in Google Native Client
  • the built-in Print preview and print system
  • no stable version offered by the official team (aka The Chromium Authors)
  • no digital signature
  • no auto-update system (Solutions: Use an #updater • Use PPA on #linux)
  • no Google API keys (Solution: Check the #google-api-keys part)
  • no built-in Flash player (Solution: Check the #flash part)
  • no support of proprietary codecs (AAC, MP3, H.264) (Solution: Check the #html5-audio-video part)
  • no user RLZ identifier
  • no user metrics (usage statistics) (opt-in option)
  • no crash report (opt-in option)
  • More details on the official site, focused on Linux.

Some developers maintain forks of Chromium that offer more features and enhancements. Thanks a lot for developers! ;)

Google API keys

A yellow disclaimer message appear as a doorhanger:
Google API keys are missing. Some functionality of Chromium will be disabled. Learn More
Sometimes you need to use Google API keys to talk to some Google services (Sync, Speech, Hotword, Translate, Now, Hangout...). And then you Google a bit and follow all the instructions. But the Chromium Project's API keys page does a not-so-great of explaining how to do this, so I will.

1. Without your own Google API keys

On #windows: Launch Command Prompt (cmd.exe) and enter the following commands:
setx GOOGLE_API_KEY "no"
setx GOOGLE_DEFAULT_CLIENT_ID "no"
setx GOOGLE_DEFAULT_CLIENT_SECRET "no"

Now launch Chromium. Enjoy! ;)

2. With your own Google API keys

(Based on an original tutorial wrote by Chris Van Wiemeersch)

  1. Clicking on that yellow disclaimer message takes you to the confusing API keys docs page.
  2. If you aren't already, subscribe to the chromium-dev@chromium.org mailing list. (You can just subscribe to the list and choose to not receive any mail. FYI: the Chromium project restricts the APIs to those subscribed to that group - that is, Chromium devs.)
  3. Make sure you are logged in with the Google account associated with the email address that you used to subscribe to chromium-dev.
  4. Log in to the Google Cloud Platform, and select an existing project or press the "Create Project" button.
  5. From the project's API Manager, select the Credentials tab in the sidebar.
  6. Create a Browser API Key.
  7. You'll see a modal with an API key. Copy and paste that somewhere.
  8. Now create an OAuth Client ID.
  9. After you complete all the steps and the "content screen", you'll be presented with a modal with your Google Client ID and Client Secret.
  10. You'll need to set three environment variables:

On #windows: Launch Command Prompt (cmd.exe) and enter the following commands:
setx GOOGLE_API_KEY yourkey
setx GOOGLE_DEFAULT_CLIENT_ID yourclientid
setx GOOGLE_DEFAULT_CLIENT_SECRET yourclientsecret

On #mac. In the shell, type:
launchctl setenv GOOGLE_API_KEY yourkey
launchctl setenv GOOGLE_DEFAULT_CLIENT_ID yourclientid
launchctl setenv GOOGLE_DEFAULT_CLIENT_SECRET yourclientsecret

On #linux: Plop these in your ~/.profile file:
export GOOGLE_API_KEY="yourkey"
export GOOGLE_DEFAULT_CLIENT_ID="yourclientid"
export GOOGLE_DEFAULT_CLIENT_SECRET="yourclientsecret"

Now launch Chromium. Enjoy! ;)

Flash

There is 1 type of Flash plugin for Chromium:
  • The PPAPI plugin: PepperFlash
  • The NPAPI plugin: Flash Player (#npapi)

PepperFlash is secure because it works in a sandbox. In short, it executes in its own process, separate from the browser's rendering engine.

The simplest way:
On Windows and macOS, Chomium find PepperFlash itself (= without #command-line-flags)

  1. Install Chromium (WebRTC must be natively enabled in Chromium. Check Nik builds on #windows or Marmaduke builds on #mac)
  2. Install PepperFlash (PPAPI) from Adobe.
  3. Check chrome://flash
  4. Disable "Ask first" in the chrome://settings/content/flash page (screenshot)
  5. Test if animation works on the Flash Player versions page.
  6. Enjoy!

Now, the full manual installation tutorial...
(If Google Chrome is already installed, go directly to the step 3: #add-command-line-flags)

1. Get PepperFlash (PPAPI)

This plugin is a non-free (proprietary) software developed by Adobe, and distributed bundled with Google Chrome. So get it from the official sources: Adobe or Google.

1.1 From Adobe

Different official ways:
After install, the plugin path will be:
- On a 64-bit #windows:
  • C:\Windows\system32\Macromed\Flash\pepflashplayer64_[version].dll (64-bit version)
  • C:\Windows\SysWOW64\Macromed\Flash\pepflashplayer32_[version].dll (32-bit version)
- On a 32-bit #windows:
  • C:\Windows\system32\Macromed\Flash\pepflashplayer32_[version].dll (32-bit version)

1.2 From Google Chrome

Canary channel:

1.3 From an unofficial source

(Use an online service to prevent #malware)
  1. Search "PepperFlash" or "PPAPI" at [RU] effect8.ru or patheticcockroach.com
  2. Download and open the .7z archive
  3. Get "pepflashplayer.dll" (rename it, if needed) and "manifest.json" files.

Optionally, get the Flash version number:
(If you want to see the correct version number on Chromium internal pages)
  • On all platforms, open the manifest.json text file in the PepperFlash folder.
  • On Windows, you can do a right-click → Properties → Details, on the .dll file

2. Change the plugin directory

If you want, prefer a short path for the plugin. It will be easier for the next step. ^^
Example on Windows: Put this .dll file in a path like C:\PepperFlash\ (Create the directory if needed)

3. Add command-line flags

Use these #command-line-flags:
  • --ppapi-flash-path=[plugin path]
  • --ppapi-flash-version=[plugin version]
  • And optionally --allow-outdated-plugins to disable browser notifications about outdated plugins

On #windows, create a Chromium shortcut. Then go to its properties and edit the target field: --ppapi-flash-path="C:\PepperFlash\pepflashplayer.dll" --ppapi-flash-version="28.0.0.126" --allow-outdated-plugins
On #mac, you will need to launch it from the command-line (in the Terminal): /Applications/Chromium.app/Contents/MacOS/Chromium --ppapi-flash-path=/Library/Internet\ Plug-Ins/PepperFlashPlayer/PepperFlashPlayer.plugin --ppapi-flash-version=28.0.0.126& The "&" at the end is not a typo. It is there to make sure Chromium is launched in a separate thread. Without the "&", Chromium would exit as soon as you quit the Terminal. Moreover, to simplify the Chromium launch, check How to create simple Mac apps from shell scripts (Archive: 1). Also see the #comment-566 and #comment-344.

4. Restart the browser

Relaunch it to apply changes.

5. Check the installation

6. Enjoy!

Now, even after browser updates, Chromium uses PepperFlash. ^^

NPAPI plugin support

Chromium build 45.0.2416.0 (331982) is the last version which still has NPAPI plugin support enabled via chrome://flags or group policy registry. (sourceNPAPI deprecation)

Solutions to still use NPAPI plugins:
  • Switch to another browser like Firefox (Plugin roadmap, NPAPI deprecation) or Waterfox still supporting NPAPI plugins.
  • or install an older Chromium version (Ex: 331982, 331959, 331938, 331935...)
  • or install the IE Tab addon which allows users to view pages using the IE layout engine

More info on site archives:

HTML5 audio/video

By default, Chromium does not support proprietary codecs (AAC, MP3, H.264/MP4) in the HTML <audio> and <video> elements.

Solutions:
  • Use Nik builds on #windows or Marmaduke builds on #mac. All codecs are enabled ^^
  • or compile Chromium from #source-code
  • or install an older version having ffmpegsumo file (Ex: 333350, 333334, 333283, 333258...)
  • or choose other #browsers
  • On #linux, you can use Chromium with proprietary codecs

Before 4 June 2015, we used an alternative with the Google Chrome ffmpegsumo file and our Patch HTML5 Media extension. More info on site archives:

1. Check HTML5 audio/video support


If there is a video issue, disable hardware acceleration (see #browser-crash).

Advanced

1. Internal pages

To access to all internal pages, use chrome://about. Copy and paste this special URL directly into the address bar (omnibox).
Obviously, this special URL works only in Chromium and Google Chrome.

About plugins
Since version 57, the chrome://plugins page no longer exists. (official source)

Info:

Few internal pages:
Note: About configuration settings, there is nothing similar to Firefox's about:config in Chromium.

Example: How to clear DNS cache?
Open chrome://net-internals/#dns and click on the Clear host cache button.

2. Keyboard shortcuts

To use keyboard shortcuts (on Windows, Mac and Linux), check this full list of official shortcuts... and this one if you are developer. Most of the shortcuts are similar to IE, Firefox or any other browser.

3. User data directory

About your bookmarks, profile... it is important to know where is stored your user data.

4. Command-line flags

There are command-line flags (or "switches") that Chromium accept in order to enable particular features or modify otherwise default functionality. Note flags often contain experimental or obsolete code, so they tend not to stick around for long.
Example: How to start Chromium directly in incognito (or private) mode on Windows?
Add flag at the end of the Chromium shortcut and restart the browser. (screenshot)
"C:\{...}\Chromium\Application\chrome.exe" --incognito

5. External extension installation

How to install an external brower add-on?
  1. Get source .crx file of any extension directly from the Chrome Web Store via CRX Viewer, Chrome extension source viewer, Get CRX or via a site like Chrome Extension Downloader, Crx4Chrome
  2. Go to chrome://extensions
  3. Drag and drop the .crx file on the page

If it does not work...
  1. Unzip the .crx file
  2. Go to chrome://extensions
  3. Drag and drop the unzipped folder on the page... or click on Developer mode then Load unpacked extension...

About updates:
  • You have to update manually
  • You can update when you want! ^^
  • If ever a new version sucks, just re-install the previous one

6. Source code

Before all, check the official guide for developers.

Official links to easily get or see the full Chromium source code:
Interesting info:

7. Older version

Never update your browser with a very old version. It even does not start.

To downgrade Chromium installed with the Installer (.exe):
  1. Open Chromium and check its actual version at chrome://version
  2. Close Chromium.
  3. Uninstall Chromium WITHOUT to delete your #user-data-directory. It is an option of its uninstaller. (screenshot)
  4. Get the Installer (.exe) of an older version (from the → download/ page or Snapshots repository about "official" builds)
  5. Execute it to install Chromium.
  6. Open Chromium and check the new installed version at chrome://version

8. Browser crash

You have encountered a browser crash or issue :/

Few ways to help you:
- To disable hardware acceleration: - To disable/enable a browser feature: chrome://flags
- To check for conflicting software: chrome://conflicts
- To disable extensions/add-ons: chrome://extensions

Also you can use #command-line-flags: --disable-extensions, --disable-gpu, --disable-accelerated-video-decode...
Note that incognito mode disables all extensions by default.

API

This is a free and simple API for developers to update Chromium to the latest good build via a bash (shell) script, an add-on... Read my #notes.

Please, do not use this API to build other websites. To prevent abuse, the site can audit each API request.

GET request parameters:
  • os(required) windows or mac or android
  • bit(optional • 64 by default) 64 or 32
  • out(optional • json by default) json or string or xml or revision

Response:
chromiumwindows or mac or android
  • architecture(string) 64-bit or 32-bit
  • timestamp(integer) Unix time of this release built on the Chromium Buildbot server
  • editor(string) The Chromium Authors
  • channel(string) dev
  • repository(string) snapshots
  • version(string) (like xx.x.xxxx.x)
  • revision(integer) Git revision's commit position
  • commit(string) Git revision's commit hash

Basic examples:
Example to get the latest build with the outrevision parameter:

Browsers

1. Open-source browsers

2. Chromium forks

In simple words, a fork of Chromium means Chromium engine is used to create another web browser.

Proprietary browsers:
(developed by official contributors of the Chromium #project)
I do not recommend:
Why not recommended?
Because all of these browsers are closed-source, outdated, based on Chromium (like Google Chrome and Opera)... and most of the features they remove don't even exist in Chromium, in the first place. Control your personal info and #privacy yourself ^^

Moreover, InsanityBit explains this very well on his blog: SRWare Iron Browser – A private alternative to Chrome? (2012 • Archives: 1, 2)

Note if a new browser with "better privacy" than Google Chrome is based on Chromium and is fully open-source, it should be ok for me. But... Google is famous. Its private policy and marketing strategy are well known. So you have to ask you some questions. Do you trust in an unknown team more than Google? Is an outdated Chromium fork?
Few free and open-source Chromium forks:

Privacy

For a better privacy protection, use open-source #browsers like Chromium or Firefox. Do not forget: It is open-source does not mean it is secure and respects user privacy (and security ≠ privacy). But, if your browser is fully "open-source", it means that somebody with the capability can review the #source-code. With versioning tools like SVN or Git, it is easy for developers to find malicious code (Ex: Chromium downloads a Chrome extension as a binary without source code). Only an open-source code allows such defense. This is better for secure browsing and user privacy. While I recommend Firefox as the most reliable browser for privacy enthusiasts (cf. about:config settings), Chromium is probably a reasonable alternative for everyday web browsing.

My way (but do as you like ^^):
  1. Modify your #hosts-file to stop "natively" domains who serve ads, spyware and malware
  2. Use a VPN with strong encryption for your whole OS or router (It is better than browser VPN/proxy #extensions)
  3. Use an up-to-date web browser
  4. Change few #browser-settings
  5. Install few #extensions

You cannot be anonymous on web even using a VPN or TOR network. But you can protect your privacy against user tracking tools. These tracking and profiling tools are everywhere today. You can find them both in software and websites.

1. Browser update

The reason for updating to the latest version is security. As security threats are found, they are fixed. Using an old version expose user to a number of security holes and privacy issues. Browsers are far more subject to hacking than other software.

2. Browser settings

Adjust all settings and advanced settings in chrome://settings:

3. Hosts file

Modify your hosts file to prevent your OS from connecting to domains who serve ads, spyware and malware. This will increase your OS security and save bandwidth.

Note:

4. DNS services

By default you are using the DNS servers of your ISP but you do not have to stick with them. Free alternative Internet DNS services for personal use:

5. Search engines

Choose a web search/metasearch engine:
If you are a web developer, do it yourself ^^

6. Extensions

Note: Extensions hosted on Chrome Web Store are updated via the Chrome update mechanism (cf. Chromium source code) which developers and users do not control. For a manual installation, read the #external-extension-installation part.

Add-ons for Chromium (and Firefox):

Block ads, trackers, scripts and popups

uBlock Origin + uBO-Extra

Stop everyone from tracking you

uMatrix

Force to use secure connection of websites (https://)

HTTPS Everywhere

Control the HTTP Referer on a per-site basis

Referer Control

Prevent canvas fingerprint

Canvas Defender

Emule locally CDN

Decentraleyes

Prevent WebRTC IP leak

WebRTC Network Limiter removed

Remove UTM tracking tokens from URLs

Tracking Token Stripper
  • Download: store, amo
  • Alternatives: Link Cleaner, Clean Links
  • Info: UTM

Display sites quality

WOT (Web of Trust)

Unblock websites with a browser VPN/proxy

Browsec

Stop link redirection in Google and Yandex search pages

Google search link fix
Note:
  • If you use WOT (Web of Trust), do not share your data. (WOT settings → Real-time protection → Set to off)
  • About WebRTC: Extension can only blocks the leak of your IP address. It does not blocks WebRTC in the "core" of Chromium.
  • Browser VPN/proxy: Do not use Hola! or ZenMate. Hola! is a botnet. ZenMate needs a free user registration. (Prefer to pay for a safe and secure VPN service... or use a free VPN service without registration)
  • If you use Adblock Plus or AdBlock, disable "Acceptable Ads" option.
  • uBlock Origin (wiki) is pattern-based filtering, while uMatrix (wiki) is matrix-based filtering which gives you more control over the filtering process.
  • uBlock Origin can also protect against WebRTC IP leak.
  • Add filters to your ad-blocker via FilterLists website.

7. Tools

8. Guides

9. Tests

Reputable and reliable sites to show or prevent user data tracking:

Malware

Your antivirus detects a malicious software in Chromium files.

False positive?

You have downloaded Chromium from a reliable source (#notes) and maybe also used an open-source #updater. In this case, it is a false positive. The detection is generic (heuristic). There is absolutely no backdoor or other malware inside. Remember that the full #source-code is available! More on #privacy...

These reports are known for few years ago:

Authentic malware?

Yes, it is possible. The common entry methods for Chromium virus are freeware downloads as bundled software (bundleware) and spam e-mails. It means Chromium has been silently installed via another software. Do not forget Chromium is free and open-source. So malware writers use Chromium to push malicious code on to your system. Remove this "fake" Chromium version or suspicious web browser (like BeagleBrowser, BoBrowser, BrowserAir, Chedot, eFast, Fusion, MyBrowser, Olcinium, Palikan, Qword, Torch, Tortuga...).

Check files on your OS

Free tools to check your OS:
Free online services (without registration) to check your file:
If you find an issue:
  • Contact your anti-virus or anti-malware support
  • Report it on the official Chromium supports. For links, see my #comment-1 below.

Chromium updater

To update Chromium automatically.

As always, never install a closed-source software especially if you have never heard it before! SearchCode, GitHub (and its Gist service) are good places to find good stuff. So, try these open-source Chromium updaters:

For Windows:
For macOS:
For Android:
Browser extensions:
Discontinued projects:
Thanks a lot for developers!
I do not support these tools. Please, contact the developers for thank, issue, help...

@Anon 2769 I have a relatively fresh internal test build dealing with various LLVM options, so I will share it. :)

Targeted optimizations include -O3 for hot code, though -Os for remaining code to keep file sizes within reason as it is not a lightweight build. o.0 FullLTO is not enabled due to annoyingly long build times. As usual, it is an *experimental* build. YMMV.

If anyone else using Polly is looking at the -Os optimization level with a question mark, these days Polly will work with other levels offering autovectorization instead of just -O3 as indicated in the older documentation. :) I still have the habit of passing -vectorize-loops and -vectorize-slp anyway, and it is not a bad idea IMO since I have seen autovec disabled for whatever reason(s) even it was expected to be enabled.

I was finally able to spend a few minutes cleaning up and updating the Polly config based upon a skim through recent source code. I likely will start enabling standard tiling for future generalized Polly builds since the default tuning should be okay for many modern processors.

My symbolic directory link setup just resulted in a sandboxing error. The quick fix was simply moving Chromium back to its default directory for now. Something to look at later. Anyway....
@Marmaduke: No sync • 65.0.3292.0 => simply perfect! ;-)

Polly Build
Octane Score: 34638
JetStream: 164.79 ± 1.5436
Speedometer 2.0: 64.17

Marginally better than your normal dev builds, however, I noticed some crashes with sites using JWPlayer to server video content. One chrome.exe process is pinned to 25% CPU usage and requires a kill task via task manager, otherwise it's just frozen. But other than that, normal browsing, you're all good.
@Anon2776 Thanks for the feedback. :)

I suspected there could be some (or even many) issues, as I was compile testing primarily for build breakage instead of browser usability with those numerous LLVM options. Good to see usability is not too bad. The options should be dramatically paired down for an actual public Polly build, which should improve usability.
@2771: i'm trying but got some errors, so wait for it
New ThinLTO build going live in a few minutes. Updated compiler optimizations. Hot code still at -03. Remaining code now at -Os. Extended the compiler's software pipeliner down to -Os as well. Upped the link time optimization level to the most aggressive level.

It is one of the quicker ThinLTO builds in recent times acccording to a few benchmarks I casually ran. Plus I still need to evaluate other options, such as tweaking register allocation, before going public with them in ThinLTO.

BTW, the sandboxing error with using Chromium via a symbolic directory link is resolved, too. Think it was due to a NaCL workaroud I had applied with the previous Polly build.
@Marmaduke new stable build for us this weekend?

As always, thanks Warren! :)

I too have noted some performance regressions in recent weeks with various builds; ThinLTO and otherwise.

I cranked up LTO agressiveness to max to hopefully help.

The -Os code paths should not matter much, but I will reeval to verify. I was trying to reign in code size a little along the colder code paths, but I can go back to -O3 across the board easily enough if needed be.

I still would like to get PGO working with Clang+LLD, but as of this week, it continues to not profile the needed renderer process(es). I still have another idea or two about PGO, but it is getting around to them as I feel up to it.

Ok. i will wait. I hope you relsove errors.
Thank's anyway.
Just rolled a test build of the same ThinLTO revision but at -O3 across the board. No big benchmark changes for the most part, but t did gain upwards of an 100 points in Peacekeeper.

Looks like I will go back to bulding all targets at -O3. I will try to get a new release out in the next day or two.

Appears to be a false positive, it happens at least since v61. No idea why Baidu engine still considers those builds have ties to WisdomEyes.
Also, if you'd have checked other earlier builds including zip, sync and 32bit flavors, you'd find a couple other random detections from different engines.
Latest ThinLTO build is back to -O3 for all optimized code paths.
