Biome alternatives

7 other tools do this job. Which one is right depends on why Biome is not working for you — so start from the reason, not the list.

Why teams leave Biome

  • Rule coverage does not yet match ESLint's plugin ecosystem.
  • No support for framework-specific plugin ecosystems at ESLint's depth.
  • Young project, so expect churn.

Worth saying: Biome is genuinely strong at this — dramatically faster than eslint plus prettier, which matters on pre-commit hooks. If that is the part you rely on, switching may cost more than it saves.
