Bifrost
A high-performance AI gateway that provides a single OpenAI-compatible endpoint across 15+ AI providers with automatic failover, intelligent load balancing, semantic caching, and MCP tool integration — claiming sub-100µs overhead at 5k RPS.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
MCP bridge/proxy for connecting different agent frameworks. Security depends on connected systems. Treat as infrastructure component requiring high trust.
⚡ Reliability
Best When
You are running high-throughput AI workloads across multiple providers and need enterprise-grade failover, cost controls, and minimal latency overhead.
Avoid When
You only use one LLM provider and have no need for failover or multi-key load balancing.
Use Cases
- • Centralizing LLM API access across OpenAI, Anthropic, AWS Bedrock, Google Vertex, and Azure behind one endpoint
- • Achieving high availability with automatic failover when a provider goes down
- • Reducing LLM costs via semantic caching and intelligent load balancing across multiple API keys
Not For
- • Teams needing a managed SaaS gateway with vendor support — this is self-hosted
- • Simple single-provider setups where routing complexity adds unnecessary overhead
- • Non-Go shops that cannot maintain a Go service in production
Interface
Authentication
SSO via Google and GitHub for the web UI. Provider API keys configured in gateway config. Budget controls apply per key/project.
Pricing
Apache 2.0 licensed. Self-hosted; costs are pass-through to underlying LLM provider APIs.
Agent Metadata
Known Gotchas
- ⚠ Performance claims (11µs overhead, 50x faster than LiteLLM) are vendor-stated and not independently verified
- ⚠ MCP integration listed as a feature but limited documentation on how agents interact with it specifically
- ⚠ Self-hosted deployment requires maintaining Go service infrastructure
