The honest brief

Agenta

Unifies prompt management, eval, and tracing in one self-hostable tool, keeping the whole loop on your own infra.

  • Self-hostable on your own infra
  • Prompt playground plus versioning
  • Human and LLM-as-judge evals
  • Built-in tracing/observability
  • Smaller ecosystem than incumbents
  • Self-hosting needs maintenance
  • Less mature than dedicated eval platforms

Langfuse

The MIT-licensed, self-hostable answer to LangSmith — own your observability data, framework-agnostic.

  • Own your observability data
  • Framework-agnostic, OTel-native
  • Tracing + evals + prompt mgmt
  • Transparent unit-based pricing
  • Self-host infra cost at scale
  • Less deep LangChain integration
  • Setup heavier than hosted-only
