A fast, production‑grade, AI Planner

Autoplan Studio solves planning and scheduling problems where others crash or time out, and shows you every step of how it got there. In your browser, with nothing to install.

Autoplan Studio showing a temporal plan for pumpcontrol, with its timeline and numeric fluent charts
Written in RustMemory-safe, with no garbage-collector pauses.1 One self-contained binaryNothing else to install: no runtime, no interpreter, no dependencies. Every plan validatedA plan is checked against the full model before it is reported as a solution. Refuses, never guessesAnything it cannot plan with is reported with its line and column, never silently dropped.

One planner for sequences, resources and time.

Temporal

Durative actions that overlap, continuous change over time, and deadlines. Plans come with start times and a makespan.

Numeric

Fuel, capacity, money and other quantities, with costs to minimise. Resource limits are respected in every plan.

Classical

Logistics, routing and puzzles at scale, with types, conditional effects and derived predicates.

Checked and shown

Every plan is validated, then drawn as steps, a Gantt timeline and charts of every quantity it changes.

What is AI Planning?

States, actions and goals, how planners search, and where planning is used.

The PDDL guide

The syntax, a walkthrough, and what changed from PDDL 1.2 to 3.1 and PDDL+, with examples you can run.

The planners

LAMA, ENHSP, POPF, OPTIC and others: who built them, how they work, and their papers.
Engineered for production

Built to run in critical systems.

Fast enough for real deadlines, predictable under load, and every plan checked before you see it.

Rust, end to end

The parser, planner and validator are all written in Rust. This rules out a whole class of memory errors and latency issues, such as garbage collector pauses, guaranteeing robust, consistent, and efficient runs.

Memory you can see

Peak memory and search progress are reported live on every run, so a hard problem shows where its time and memory go.

Deploys as one file

The planner is a single native binary with no runtime or interpreter. Autoplan Studio runs that same binary, so what you see here is what you deploy.

Traceable builds

Every build reports the exact version it was made from, so a result can always be traced back to the code that produced it.

1 Unsafe code is confined to a handful of small, reviewed low-level calls, such as reading memory usage and counting allocations.
