The [Baseline Features diagnostic
audit](https://developer.chrome.com/docs/lighthouse/best-practices/baseline-features)
is available in [Lighthouse](https://developer.chrome.com/docs/lighthouse) in
the Best Practices audit category. This audit reports the [Baseline](https://web.dev/baseline)
status of web platform features detected on a page, providing browser
interoperability information directly within Lighthouse reports.

The [`web-features` package](https://www.npmjs.com/package/web-features) powers
this audit, which identifies web platform features used on a page, including
features in third-party scripts and active browser extensions. It identifies the
Baseline status of each detected feature---Widely available, Newly available, or
Limited availability---and lets you see where the feature appears in the page
source code, with links to web feature entries on
[webstatus.dev](https://webstatus.dev/).

The Baseline Features audit is available in the current version of Lighthouse
and Chrome DevTools. You can run it on any page in Lighthouse to inspect feature
usage and read browser compatibility data.
