Best for	Teams making evaluation a first-class part of development Organizations wanting CI/CD quality gates for AI Product and AI engineering teams iterating on prompts	Teams wanting simple, cheap LLM logging Developers self-hosting an open-source gateway Cost and usage monitoring across providers
Pros	Deep, eval-first feature set with scorers, experiments, and statistical rigor Strong CI/CD integration to catch regressions before deploy Usage-based pricing with unlimited users, so no per-seat penalty Powerful playground for prompt iteration and comparison Tight loop between production logs and evaluation datasets	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	Not open source; source-available and hosted model Self-hosting locked to the Enterprise tier and a license key Big price jump from free to $249 per month SSO, RBAC, and self-host are gated behind Enterprise Data- and score-based billing makes costs less predictable at volume	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
