Best for
  • Engineering teams treating evals like tests
  • Teams gating deployments on LLM quality
  • RAG and agent developers
  • Document-heavy RAG applications
  • Enterprise knowledge agents
  • Teams needing reliable PDF parsing
Pros
  • pytest-style workflow fits developer habits
  • 50+ research-backed metrics out of the box
  • Apache-2.0 and free to use
