Other API endpoints

For historical reasons, LATEST_RELEASE_ files containing fully qualified version numbers are available as well.

1. E.g. https://googlechromelabs.github.io/chrome-for-testing/LATEST_RELEASE_116 answers the question “what’s the latest available version within milestone 116?”.
2. E.g. https://googlechromelabs.github.io/chrome-for-testing/LATEST_RELEASE_116.0.5845 answers the question “what’s the latest available version within the 116.0.5845.* range?”.
3. E.g. https://googlechromelabs.github.io/chrome-for-testing/LATEST_RELEASE_STABLE answers the question “what’s the latest available Stable channel version?”. Similar for the other channels (BETA/DEV/CANARY).

These can be used instead of the latest-versions-per-milestone, latest-patch-versions-per-build, and last-known-good-versions JSON API endpoints respectively.

Additionally, each version from the known-good-versions-with-downloads.json is published as a separate JSON file containing its download URLs — for example, 123.0.6309.0.json.

You can browse the complete list of JSON and text files.

FAQ

What is Chrome for Testing?

Chrome for Testing is a new Chrome flavor that specifically targets web app testing and automation use cases. Read Chrome for Testing: reliable downloads for browser automation for more details.

What’s the easiest way to download Chrome for Testing binaries?

Use @puppeteer/browsers.

macOS says the *.app is damaged. What now?

On macOS, if you download a Chrome for Testing ZIP file using a browser instead of via @puppeteer/browsers, curl, or wget, you might get this warning:

“Google Chrome for Testing.app” is damaged and can’t be opened. You should move it to the Trash.

This happens because macOS Gatekeeper sets an extended attribute that marks the ZIP file and any files within it as “downloaded via a browser” and thus potentially dangerous.

To fix the problem, recursively remove the extended attribute:

xattr -cr 'Google Chrome for Testing.app'
