Bifrost - Ultra-fast Enterprise AI Gateway

Bifrost is an enterprise AI Gateway that unifies 15+ providers and 1,000+ models through a single OpenAI-compatible API. It connects OpenAI, Anthropic, AWS Bedrock, Google Vertex, and more all at once, runs instantly with no configuration, and provides real-time monitoring and analytics through a built-in web UI. You can switch providers without any code changes by simply changing the base URL of your existing API.

With automatic failover and intelligent load balancing, it distributes traffic across multiple providers and API keys. In its performance overview, it claims to be 50x faster than LiteLLM, and highlights under 100µs overhead at 5k RPS.

It handles text, image, audio, and streaming through a common interface, and reduces the cost and latency of duplicate requests with Semantic Caching. MCP support and Custom Plugins also enable integration with external tools such as filesystems, web search, and databases, as well as custom middleware extensions.

Deployment options include npx -y @maximhq/bifrost, Docker, Go SDK, and HTTP Gateway. It also includes security and governance features such as budget management at the virtual key, team, and customer level, rate limiting, SSO, and HashiCorp Vault integration. It is licensed under Apache-2.0 and implemented in Go.
