Why is Apache Burr currently going through Apache Incubation, and what does that mean for production use?

The Apache Software Foundation requires every newly accepted project to go through incubation until its infrastructure, communications, and decision-making process have stabilized to match other established ASF projects. Burr entered incubation after Stefan Krawczyk and Elijah ben Izzy proposed donating it, with ASF mentors including Kevin Ratnasekera, Ayush Saxena, PJ Fanning, and Jarek Potiuk overseeing the process.

Incubation status is explicitly not a judgment on code quality or completeness — it’s a governance milestone. That said, it does mean the public API can still evolve before graduation to a top-level project. A June 2026 community write-up comparing Burr to LangGraph and CrewAI noted Burr already had over 400,000 PyPI downloads and an active community, with a core state machine and persistence model described as stable, but recommended production users pin their installed version and watch the release changelog rather than assume total API stability, since Burr is still incubating.
