Chromium Code Search

The Chrome Developer Tools are a set of web authoring and debugging tools built into Google Chrome.

Chromium is a free and open-source software project developed by the Google-sponsored Chromium project. The source code can be compiled into a web browser. New versions of the code are published daily. Google uses the code to make its Chrome browser, which has more features than Chromium.

You can use Xpath or Css by using the search function inside Elements panel. Let’s see how we can do this.

  • Press F12 to open up Chrome DevTools.
  • Elements panel should be opened by default.
  • Click on some element.
  • Press Ctrl + F to enable DOM searching in the panel.
  • Type in XPath or CSS selectors.
  • If system finds something, result will be highlighted in DOM.

You can check your Xpath/Css by evaluating javascript code in Chrome Console.

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 Point and Click for latest build:

Easy Script to download and run latest Linux build:

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.
  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.
