Bifrost
FreemiumOpen-source AI gateway for routing, governing and monitoring LLM calls
What is Bifrost?
Bifrost, from Maxim AI, is an open-source gateway that sits between your apps and LLM providers, adding routing, budgets, guardrails and observability. It is a drop-in replacement for provider SDK endpoints, so moving traffic through it usually means changing one base URL.
It works with the OpenAI and Anthropic SDKs, the Vercel AI SDK, LangChain and similar clients. Teams can set budgets per team or virtual key, keep audit logs, enforce SSO access and block unsafe outputs with guardrails, while metrics and traces follow OpenTelemetry formats.
A built-in MCP gateway lets agents reach tools through the same layer. The open-source version self-hosts with Docker, Kubernetes or a Go binary and starts with one npx command; Bifrost Enterprise adds licensed features with a 14-day trial.
