Bifrost is an Open Source LLM Gateway written in Go by Maxim AI (H3 Labs Inc.) that provides a unified, OpenAI-compatible API for accessing 20+ model providers (including OpenAI, Anthropic, AWS Bedrock, Google Vertex, and Azure). It offers governance features such as virtual keys, budget controls, automatic failover, load balancing, semantic caching, and an MCP gateway. Bifrost is deployable as an NPX package, Docker container, or Go library and serves both individual developers and enterprise customers with additional governance, security, and observability features. The project is licensed under Apache-2.0 and is also offered as a paid enterprise version with private cloud/on-premise deployment.
