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

Userpilot

  • Starter tier limited to 2,000 monthly active users; even small-to-medium products may require Growth tier
  • Large price jump from Starter ($299/mo) to Growth ($849/mo), nearly 3x increase
  • Growth tier scales to 100,000 MAU but does not publish pricing for higher volumes, requiring Enterprise negotiation
  • Session replay and mobile engagement are optional add-ons in Growth tier, not included in base pricing
  • Enterprise pricing not published; custom negotiations required for large-scale deployments
