Best for	Teams routing production traffic across many LLMs Organizations needing governance and reliability tooling Developers wanting an open-source, self-hostable gateway	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
Pros	Fully open-source, self-hostable gateway for data control and no lock-in Access to more than 1,600 models through one API Broad feature set spanning observability, guardrails, routing, prompts, and cost control Transparent, relatively cheap entry with free and ~$49 tiers Battle-tested at very large scale	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
Cons	Adds a network hop and dependency in the critical request path Log-volume-based pricing can get complex or expensive at scale Free-tier logging caps and short retention are tight for real debugging Self-hosting the open-source gateway shifts ops burden to you It is a gateway and ops layer, not a full build-and-eval IDE	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
