Best for
  • Engineering teams treating evals like tests
  • Teams gating deployments on LLM quality
  • RAG and agent developers
  • Teams operating at large scale
  • Billion-vector search workloads
  • Enterprise RAG and search
Pros
  • pytest-style workflow fits developer habits
  • 50+ research-backed metrics out of the box
  • Apache-2.0 and free to use
  • Covers RAG, agents, conversations, and safety
  • Integrates into CI/CD for quality gates
  • Open source under Apache 2.0, free to self-host
  • Proven at billion-vector scale
  • Distributed, cloud-native architecture
  • Multiple index types and GPU acceleration
  • Hybrid search and rich filtering
Cons
  • Eval reliability depends on judge model/config
  • Competitive, crowded evaluation category
  • Richer collaboration features require Confident AI cloud
  • LLM-as-a-judge adds model API costs
  • Requires writing and maintaining test suites
  • Operationally heavy to self-host at scale
  • Multi-component architecture adds complexity
  • Overkill for small or simple projects
  • Steeper learning curve than embedded databases
  • Zilliz Cloud compute-unit pricing needs modeling
