When to stay with Langfuse
Documented strengths from our Langfuse review — switching isn't always the right call:
- Fully open source under MIT — all core observability, eval, prompt, and dataset features are free when self-hosted, with no functional gating on the OSS core
- Framework-agnostic via OpenTelemetry; integrates natively with LangChain, LlamaIndex, OpenAI SDK, and LiteLLM through Python and JS SDKs
- Cloud paid tiers include unlimited users, avoiding the per-seat scaling that competing observability platforms charge
