OpenPlan Labs

Open tools for automated planning — CUDA-accelerated and classical planners, multi-agent pathfinding, and PDDL tooling.

Everything here is an implementation of published work, written to be read as well as run. Each README says what the tool does and what it does not do; if one doesn't, that is a bug worth filing.

Multi-agent pathfinding

Repository What it is
pymapf Python library for multi-agent planning and pathfinding, centralized and decentralized. On PyPI.
cuda-planning The same algorithms batched onto a GPU, with a NumPy reference backend. Installs as cuplan — the repository and the distribution are deliberately named differently.

PDDL & classical planning

Repository What it is
PythonPDDL Dependency-free, pure-Python PDDL planning framework: parser, grounder, planners, heuristics, and a benchmarking harness. Installs as jupyddl.
pddl-examples Curated PDDL domains and problems. Planners not included. Contributions of new instances are welcome.
awesome-pddl Curated list of PDDL resources — planners, editors, tutorials, papers.
docker-pythonpddl PythonPDDL in a container, for running without a local Python setup.

Measurement & figures

Repository What it is
openplan-bench One harness, one problem set, one results schema for every planner here. Timeouts and errors are recorded as rows, not dropped. Leaderboard.
planviz Grid maps, search animations, plan timelines and benchmark charts, light and dark from the same call. Planners not included — it draws results, it does not produce them. On PyPI.

Meta

Repository What it is
branding The Frontier brand system — palette, mark, type, figure conventions. If a repo's colours drift from it, it wins.
.github Org-wide defaults: contributing guide, code of conduct, security policy, issue templates.

Get involved

Bug reports and PDDL instances are the easiest ways in; both have templates. The contributing guide covers the PR flow, and each project's own README covers its specifics. Security reports go privately to the address in the security policy.
