The short version

  • Each has a real cost: ESLint slow performance on large codebases compared to newer tools like Oxlint and Biome; Read the Docs build configuration is finicky, and build failures on dependency changes are a common frustration

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

ESLint

  • Slow performance on large codebases compared to newer tools like Oxlint and Biome
  • Complexity in configuration from scratch, particularly for TypeScript support
  • Limited built-in TypeScript support, requiring separate parsers and coordination with new TypeScript features

Read the Docs

  • Build configuration is finicky, and build failures on dependency changes are a common frustration
  • Default themes are recognisable and dated, so sites look alike unless customised
  • Private documentation requires a paid business plan
  • Build times on large projects are slow enough to interrupt a review cycle
