JSON API

Static JSON, no key, no rate limit, CORS-open. Regenerated on the same schedule as the site, so an updater script can poll it directly.

Checked automatically Aug 29, 2026. Latest Chromium stable is 152.0.7977.64.

Endpoints

Endpoint	Returns
`/api/v1/builds.json`	Every tracked build with all downloads, checksums and metadata.
`/api/v1/latest.json`	One flat row per build with the preferred download URL. The best endpoint for an updater.
`/api/v1/upstream.json`	Current upstream Chromium stable, beta, dev and canary versions with revisions.
`/api/v1/windows.json`	Windows builds only.
`/api/v1/macos.json`	macOS builds only.
`/api/v1/linux.json`	Linux builds only.
`/api/v1/android.json`	Android builds only.
`/api/v1/distros.json`	Chromium version currently packaged by each Linux distribution.

Example

# newest Windows x64 build that is level with upstream stable
curl -s https://chromiumbuilds.org/api/v1/windows.json \
  | jq -r '.builds[] | select(.arch[0]=="x64" and .freshness=="current")
           | "\(.name) \(.version) \(.downloads[0].url)"'

Field notes

freshness is derived by comparing the build's milestone against upstream stable: current, behind (one milestone), outdated (two or more), or abandoned (nothing published in a year).
sha256 comes from the release host itself, not computed here.
google is one of sync, nosync, ungoogled or raw.
Download URLs point at the maintainer's release host. Nothing is proxied through this site.

Using it

Please poll no more than hourly; the data only changes when a maintainer publishes. If you are replacing a dead update endpoint in an existing tool, latest.json is the closest shape. The generator is open source, so you can also just run it yourself.
