14 Best Bifrost Alternatives & Competitors

Bifrost is an open-source LLM gateway from Maxim AI, written in Go and self-hosted. It puts 15+ providers including OpenAI, Anthropic, AWS Bedrock, and Google Vertex behind one OpenAI-compatible API, so switching models is a config change rather than a code change. Self-hosting is the trade. You run the gateway, scale it, and stay on top of provider changes yourself, and extending it means working in Go rather than the language your application is written in. Bifrost also covers routing and reliability rather than the full picture around it, so evaluation, prompt management, and production debugging come from somewhere else in your stack. The 14 Bifrost alternatives below cover both, from self-hosted gateways like LiteLLM to hosted platforms that fold routing, observability, and evals into one product. Each links to a full profile and a head-to-head comparison.
