Download Chromium

You can test Chrome builds or Chromium builds.  Chrome builds have the most infrastructure for analyzing crashes and reporting bugs.  They also auto-update as new releases occur, which makes them a good choice for most uses. Chrome Canary is available for Windows and Mac and autoupdates daily.  Other channels (dev and beta) are available.
Chromium builds do not auto-update, and do not have symbols.  This makes them most useful for checking whether a claimed fix actually works.  Use the following instructions to find builds:

Easy steps:


Not-as-easy steps:

  1. Head to
  2. Choose your platform: Mac, Win, Linux, ChromiumOS
  3. Pick the Chromium build number you'd like to use
    1. The latest one is mentioned in the LAST_CHANGE file
  4. Download the zip file containing Chromium
  5. There is a binary executable within to run

Please, file bugs as appropriate.

Downloading old builds of Chrome / Chromium

Let's say you want a build of Chrome 44 for debugging purposes. Google does not offer old builds as they do not have up-to-date security fixes.

However, you can get a build of Chromium 44.x which should mostly match the stable release. 
Here's how you find it:
  1. Look in for the last time "44." was mentioned.
  2. Loop up that version history ("44.0.2403.157") in the Position Lookup
  3. In this case it returns a base position of "330231". This is the commit of where the 44 release was branched, back in May 2015.*
  4. Open the continuous builds archive
  5. Click through on your platform (Linux/Mac/Win)
  6. Paste "330231" into the filter field at the top and wait for all the results to XHR in. 
  7. Eventually I get a perfect hit: 
    1. Sometimes you may have to decrement the commit number until you find one.
  8. Download and run!

* As this build was made at 44 branch point, it does not have any commits merged in while in beta. 
Typically that's OK, but if you need a true build of "44.0.2403.x" then you'll need to build Chromium from the 2403 branch. Some PortableApps/PortableChromium sites offer binaries like this, due to security concerns, the Chrome team does not recommend running them.
