Biome claims the bounty of the Prettier challenge!
Biome, Toolchain of the web

One toolchain for your web project

Format, lint, and more in a fraction of a second.


Built with Rust and an innovative architecture inspired by rust-analyzer.


Zero configuration needed to get started. Extensive options available for when you need them.


Designed to handle codebases of any size. Focus on growing product instead of your tools.


With tight internal integration we are able to reuse previous work and any improvement to one tool improves them all.

Actionable & Informative

Avoid obscure error messages, when we tell you something is wrong, we tell you exactly where the problem is and how to fix it.

Batteries Included

Out of the box support for all the language features you use today. First class support for TypeScript and JSX.
