LiteLLM vs OpenRouter (2026)
LiteLLM and OpenRouter solve the same problem, one API for every model, with opposite operating models: LiteLLM is an MIT licensed proxy you self host, free with zero markup on provider calls (you fund infrastructure and keys), with an enterprise license referenced around 250 dollars a month entry for SSO, RBAC, audit logs, and guardrails, while OpenRouter is a hosted gateway with no subscription, passing through provider rates plus about a five percent fee on credits, four hundred plus models behind one endpoint, and bring your own keys supported.
Self hosted control versus hosted convenience is the whole decision.
Choose LiteLLM if
- Keys, logs, and routing must stay inside your own infrastructure.
- Zero markup on provider calls matters at your inference volume.
- Enterprise controls (SSO, RBAC, audit, guardrails) on a self hosted proxy fit your compliance needs.
Choose OpenRouter if
- You want model access in minutes with no proxy to deploy or operate.
- About a five percent fee is cheap for never managing provider accounts.
- Instant access to four hundred plus models including free ones speeds experimentation.
