Bifrost

Bifrost is an enterprise AI gateway that manages LLM routing, governance, and observability with support for over 1000 models.

Bifrost is an enterprise AI gateway designed for routing, governance, guardrails, and observability across LLM, MCP, and agent infrastructures. It provides a unified interface for over 1,000 AI models from multiple providers, allowing users to switch models without changing their codebase. The system acts as a drop-in replacement for existing AI SDKs, including OpenAI, Anthropic, and LangChain, requiring only a change to the base URL to implement. Security features include real-time guardrails to block unsafe outputs, virtual key management for budget control, and SSO integration for team access. For operational reliability, it supports automatic provider failover and adaptive load balancing, while offering OpenTelemetry support for system monitoring. It is suitable for engineering teams managing production-scale AI applications that require strict compliance, auditing, and low-latency performance.
