Burr

Burr makes it easy to develop applications that make decisions (chatbots, agents, simulations, etc...) from simple python building blocks. Burr helps you ship reliable agents faster than other frameworks with it's built in real-time observability with self-hostable UI and tight developer experience that comes from it. Write code -> tracke it -> see a bug/hallucination -> create a test case for it -> ship reliable agents faster. Burr works well for any application that uses LLMs, and can integrate with any of your favorite frameworks. Burr includes pluggable persisters (e.g. for memory) to save & load application state, as well as various pluggable extensions.
