What it can do
| Tool | What it says it does |
|---|---|
audit_css | Scan CSS source and report every feature in it that does not meet a browser support target. Targets are either a Baseline level ("baseline-widely", "baseline-newly") or an explicit browser list ("chrome 120, safari 17.4, firefox 128"). Reports the offending line, what is wrong (unsupported, too… |
check_support | Look up which browser versions support a CSS property, value, selector, at-rule or function, from MDN browser-compat-data bundled with this server (no network call). Give either a BCD key ("css.properties.anchor-name") or a property with an optional value ("display" + "grid"). Also reports vendor… |
dont_make_me_think | UI/UX guidelines and a review of a page against them. mode="guidelines" returns the principles — Nielsen's 10 heuristics, Hick's and Fitts's laws, WCAG 2.2, neurodiversity-inclusive design, motion and microinteractions (including when Lottie or Rive are worth their bundle cost), SVG craft and… |
get_feature | Get everything known about one CSS feature: Baseline status and dates, the browser versions it shipped in, its description, spec links, Web Platform Tests scores, usage, and MDN reference prose. Accepts a web-features id ("container-queries") or a display name ("Container queries"). Use… |

Use this to answer questions like "which CSS features for scroll animations are Baseline yet?" or "what limited-support CSS is there for anchoring?"… |
whats_new | List CSS features that crossed a Baseline threshold within a date range, newest first. Use this to answer "what CSS can I start using now?", to write release notes, or to catch up after time away. Defaults to the last 180 days. The date is when a feature became interoperable across browsers, which… |
In its maker's words
