Where each one falls short

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

Bazel

  • Steep learning curve for developers unfamiliar with build systems
  • Initial setup complexity; requires BUILD files and Bazel configuration
  • Verbose error messages can be difficult to debug for new users
  • Smaller community and fewer third-party integrations vs enterprise tools

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
