Chromium Drift

When a browser ships an older Chromium version, its users may be exposed to known, already-patched security vulnerabilities. Plus, users on older Chromium versions don't get the latest Web APIs and features available to websites, resulting in website compatibility issues.

Why does my Chromium-based browser show a different version than this dashboard?
Browsers roll out updates gradually. The dashboard shows the version officially designated as stable, but the new version may not be available to all users for a day or two. For Chrome specifically, the dashboard waits until the day after the official stable date before showing a new milestone. You can check your own browser's Chromium version at chromiumchecker.com. Some browsers use their own versioning scheme that may not directly line up with Chromium's version numbers (this is also what makes it hard to know which version of Chromium they're based on).

How are these versions detected?
Some browsers are fetched live from public APIs on each page load, while others are detected daily via CI by extracting version info from their binaries. See the version fetching docs for details.

How often is this data updated?
Live-fetched browsers update on every page load. CI-detected browsers update once daily via GitHub Actions.

What do the colors mean?
Blue = same Chromium major version as Chrome Stable. Yellow = 1 major version behind. Red = 2 or more major versions behind.

Does being a major version behind Chrome Stable mean a browser is insecure?
Not necessarily. Some browsers intentionally track Chromium's Extended Stable channel and backport security fixes from newer releases. Being a major version behind on the version number does not always mean missing security patches.

Why isn't my browser listed?
The dashboard covers major Chromium-based desktop browsers. If you'd like to see another browser added, open an issue on the GitHub repo. Author's note: I'm still playing around with how to fetch browser versions and how to structure this website, so I won't prioritize adding more browsers until I settle on an approach I like.
