bifrost: a high-performance AI gateway providing a unified API and automatic failover across 23+ providers

What it solves

Bifrost is a high-performance AI gateway that simplifies the management of multiple AI providers. It eliminates the need to integrate multiple different APIs by providing a single, OpenAI-compatible interface for over 23 providers, while ensuring application reliability through automatic failover and load balancing.

How it works

Bifrost acts as a proxy layer between your application and various AI model providers (such as OpenAI, Anthropic, AWS Bedrock, and Google Vertex). It unifies these different APIs into one standard format. It can be deployed as a standalone HTTP gateway with a web UI for configuration, or integrated directly into Go applications via an SDK.

Who it’s for

Developers and enterprise teams building production-grade AI applications who need to avoid provider lock-in, reduce downtime via automatic fallbacks, and manage costs and usage across different models and teams.

Highlights

• Unified API: Single OpenAI-compatible interface for 23+ providers.
• High Reliability: Automatic failover between providers and intelligent load balancing across API keys.
• ** Semantic Caching**: Reduces costs and latency by caching responses based on semantic similarity.
• Model Context Protocol (MCP): Allows AI models to interact with external tools like databases and web search.
• Enterprise Governance: Includes budget management, OIDC user provisioning, and fine-grained access control.
• Extreme Performance: Minimal overhead, adding as little as 11 microseconds of latency per request.
