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

Statsig

  • Pro plan is limited to a single project, requiring Enterprise for multi-project support
  • Overage pricing on the Pro plan can become costly for high-event-volume products
  • Warehouse-native deployment and advanced access controls are gated behind custom Enterprise contracts
  • Free tier session replay and analytics retention are capped, pushing active teams toward paid tiers quickly
