Burr is completely framework-agnostic. Actions are standard Python functions, so you can call OpenAI, Anthropic, local models via Ollama, or any other provider. There is no built-in LLM abstraction layer that forces you into a specific integration.
Burr's telemetry UI is built-in and free, providing step-by-step execution traces, state inspection, and time-travel debugging out of the box. LangSmith is a separate paid service starting at $39 per seat per month. Burr's approach requires no external accounts or API keys for local debugging.
Yes. Burr includes FastAPI integration, persistent state backends, and robust error handling suitable for production. Its Apache Software Foundation incubation status signals community commitment to long-term maintenance and governance. Note that the project is still in ASF incubation, so users should evaluate maturity for their specific requirements.
Burr's overhead is minimal since it primarily orchestrates function calls and manages state transitions. The actual computational work happens in your actions (LLM calls, data processing), and Burr adds negligible latency to the orchestration layer.
Migration involves restructuring chain logic into actions and transitions. Since Burr actions are plain Python functions, existing LangChain tool integrations can often be wrapped directly. The main effort is in redesigning the flow as an explicit state machine.
The open-source version includes community support via Discord and GitHub. Burr Cloud (currently in beta) is planned to offer hosted observability and team features. Beta access is currently free; post-GA pricing has not been publicly announced but is expected to follow industry-standard per-seat or usage-based models. The Apache Software Foundation governance model ensures the project's long-term continuity regardless of commercial offerings.
Yes. Burr applications can run concurrently with isolated state, making it straightforward to orchestrate multiple agents or parallel workflows within a single service.
AI builders and operators use Apache Burr to streamline their workflow.
