Best for	Teams running multiple LLMs in production Builders of coding and AI agents Cost-sensitive LLM applications	Teams routing production traffic across many LLMs Organizations needing governance and reliability tooling Developers wanting an open-source, self-hostable gateway
Pros	Directly targets cost savings without quality loss Supports custom routers trained on your own data Low added router latency (cited ~100-150ms) Free early-access tier to evaluate Works with major providers and coding agents	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
Cons	Routing benefits depend heavily on your specific workload Exact per-token pricing is not fully published Vendor-cited savings figures need independent validation Adds an external dependency and network hop Crowded, fast-moving competitive category	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
