Busbar

Busbar is a self-hosted software that acts as an execution control plane for AI agents, enabling governance over every model request, tool call, and agent delegation. It supports multiple native large language model protocols to route, authenticate, and audit AI interactions within an organization's infrastructure without external dependencies. Busbar provides routing, budgets, circuit breaking, failover, and telemetry in a lightweight Rust binary designed for efficient deployment on-premises or in cloud environments.
