  • 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

GitLab CI/CD

  • Compute minute quotas for Premium and Ultimate tiers not disclosed in documentation
  • Additional compute minutes beyond quota incur charges; exact pricing not specified
