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

Humanloop

  • The free plan caps at 2 members, 50 eval runs, and 10,000 logs per month; every tier above that requires contacting sales, with no self-serve paid plan published, as of August 2026.
