Flint

Approachable and Fun

Fall in love with your linter. Flint’s intentional defaults and rich reporting surface only the issues you’ll want it to find.

Cache-Friendly and Fast

Flint’s intelligent caching and coordination eliminate duplicate CI workflows for tasks such as formatting and type-checking.

Powerful Typed Linting

Flint builds the most useful class of lint rules that use the full power of TypeScript’s type checker to find bugs in your code.

Streamlined Configuration

Flint configs embrace readability and power. They give you control over your linter without making you learn its internals.

Try out Flint on any web project:

npm

npx flint

pnpm

pnpx flint

yarn

yarn dlx flint

Frustrated with slow linting that doesn't catch what you actually care about?
