Apache Burr (Incubating)

Burr is a lightweight in-process python framework that standardizes the expression and execution of state machines as action-driven graphs, while making graph execution easily observable. It is particularly suited for AI agent workflows, simulations, and other dynamic systems, and comes with a self-hostable observability UI that integrates with OpenTelemetry.
