What is Bifrost?

Bifrost is an open-source AI gateway from Maxim AI. The open-source tier is free for developers, small teams and self-managed deployments.

The open-source tier includes automatic fallbacks and caching. Guardrails, cluster mode, SSO and air-gapped deployment are on the enterprise plan. Provider charges still apply to model calls, and caching reduces them.
