An ESLint plugin that checks whether the JavaScript APIs used in your code are supported by your target browsers, using browserslist and caniuse data. It reports incompatible API usage and lets you declare polyfills to suppress false positives.

Use cases

• lint browser compatibility of APIs used in frontend code
• catch usage of web APIs unsupported in target browsers
• avoid shipping code that breaks older browsers
• integrate browser support checks into CI linting
• suppress warnings for APIs covered by polyfills

When to choose

• you target a known set of browsers via browserslist
• you want static-time detection of unsupported Web/ES APIs
• your team already uses ESLint

When to avoid

• you need runtime feature detection rather than linting
• your project is Node.js-only with no browser targets
• you need CSS compatibility linting (use stylelint tooling instead)
