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.

If cost is the problem

Cheaper than Biome at the entry point, or free outright.
