Best for	Chatbot and RAG builders Teams wanting open-source observability Privacy-sensitive projects	Teams wanting simple, cheap LLM logging Developers self-hosting an open-source gateway Cost and usage monitoring across providers
Pros	Open source under Apache 2.0 Self-hostable with no per-event cost Lightweight and fast to set up Model-agnostic with LangChain and OpenAI support Free cloud tier for low volumes	Extremely easy integration via a one-line base-URL swap Open source under Apache 2.0 and free to self-host Tiny Docker image that runs almost anywhere Gateway features like caching, failover, and rate limiting cut cost and improve reliability Generous free tier of 10,000 requests per month
Cons	Free cloud tier capped at limited daily events Lighter feature set than enterprise LLMOps suites Smaller team and community than larger platforms Advanced analytics may require paid plans Self-hosting still requires operational effort	Product is in maintenance mode after the Mintlify acquisition, with no roadmap Long-term hosted-service viability is uncertain and migration may be needed Usage-based overages mean the Pro price is a floor, not a cap Short retention on lower tiers (7 days free, 30 days Pro) Large price jump from Pro to Team for compliance features
