Busbar

Self-hosted AI gateway that routes any SDK to multiple LLM providers with failover, in one binary.

PlatformWebfree

Busbar is a self-hosted AI gateway distributed as a single binary that lets an application reach several LLM providers (OpenAI, Anthropic, Gemini, Cohere, Bedrock) through one URL, with automatic failover and circuit breaking when a provider fails. It's aimed at developers and platform teams who want provider redundancy for LLM traffic without adopting a heavier gateway or hosted service. It's fully open source and runs entirely on the user's own infrastructure.
