Apache Burr: Building Reliable AI Agents and Applications

·2026.06.11 10:53

Key point

An Apache Incubating project for building decision-making AI agent applications based on Python.

Details

Apache Burr is a Python-based framework for building everything from simple chatbots to complex multi-agent systems. Instead of a DSL or YAML, it pursues a 'No Magic' approach that uses pure Python functions and decorators to define Actions and Transitions.

Key features include:

  • Built-in Observability: The Burr UI enables monitoring, debugging, tracing, and real-time state change viewing at every step of execution.
  • State Management: State can be stored on disk, in a database, or in a custom backend, allowing execution to resume from where it left off.
  • Human-in-the-Loop: Supports approval workflows that wait for human input during execution.
  • High Compatibility: Integrates with existing AI and backend stacks such as OpenAI, Anthropic, LangChain, FastAPI, and PostgreSQL without separate wrappers.

It is currently an Incubating Project of the Apache Software Foundation, focused on solving state management and debugging challenges in complex agents.
