Helicone
LLM observability platform with one-line integration
Our Take
Helicone's killer feature is its proxy-based setup — change one line (your base URL) and you're logging every request. No SDK changes needed. Note: Helicone was acquired by Mintlify in March 2026 and is now in maintenance mode (security updates, new models, and bug fixes still ship, but no major new features). Consider alternatives if you're starting fresh. Weaker on deep trace analysis compared to Langfuse or LangSmith.
Pros
- + Dead-simple proxy-based integration
- + Open source
- + Built-in caching and rate limiting
- + Clean cost analytics dashboard
Cons
- - Less detailed tracing than Langfuse/LangSmith
- - Proxy adds a network hop
- - Evaluation features are less mature
- - Acquired by Mintlify (Mar 2026), now in maintenance mode
