Unified Planning Framework
Decision gist · record as of 2026-08-14
Yes, if you need to formulate and solve automated planning problems in Python. The low install friction, permissive Apache license, and support for standard planning representations make it suitable for research and prototyping. The aging maintenance status is a minor concern—verify that external planner backends you need are still supported before committing to production use.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.8 or later; external automated planners may need separate installation depending on intended use.
- Low install friction with a pure-Python wheel distribution.
- Maintenance status is aging at 240 days since last release, though the package remains active.

What it is and what it does
Unified Planning is a framework for expressing automated planning problems in Python using standard representations like STRIPS and RDDL. It abstracts away the complexity of problem formulation, allowing developers and researchers to define planning domains, actions, fluents, and goals in a high-level Python API, then invoke automated planners to solve them.
The library depends on pyparsing for parsing, networkx for graph operations, and ConfigSpace for configuration handling. It targets researchers and developers working on AI planning, constraint satisfaction, and automated reasoning. The package is in Alpha development status and supports Python 3.8, 3.9, 3.10, and 3.11.
Use it for
- Formulate and test STRIPS-based planning problems without writing domain-specific planner syntax
- Prototype automated planning solutions for robotics, scheduling, or resource allocation tasks
- Integrate RDDL probabilistic planning domains into Python applications
- Conduct research on planning algorithms by providing a unified problem representation interface
