WebKit Bug Tracker
What it does
The official bug tracker for the WebKit project, which powers Safari on Apple platforms. Tracks rendering bugs, JavaScript engine issues (JavaScriptCore), and web platform feature requests. Filing a bug here is the primary way to report a Safari-specific compat issue or request implementation of a web standard.
Who is it for
Web developers diagnosing Safari-specific layout or API bugs, WebKit contributors working on fixes, and web compat researchers tracking cross-browser interoperability gaps in the Safari/WebKit engine.
