ESLint alternatives

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

Why teams leave ESLint

  • Configuration is a real project of its own, and the flat-config migration caused significant churn.
  • Slow on large codebases without caching.
  • Rule sprawl produces bikeshedding unless someone owns the config.

Worth saying: ESLint is genuinely strong at this — the plugin ecosystem lets you enforce almost any convention as a rule. If that is the part you rely on, switching may cost more than it saves.

If cost is the problem

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