Satisfactory Planner

A static, offline web planner for Satisfactory 1.0: from recipes to factory floor plans to the world map, logistics and trains.

• Plan production: an optimizer picks the best mix of the recipes you've unlocked for your target products and shows machines, clock speeds, power and raw resources.
• Lay out each factory: rows of machines on the 8 m foundation grid, several floors with custom shapes, and draggable entrances, exits and conveyor lifts.
• Plan power plants: coal, fuel, nuclear and biomass generators, either for a MW target or for the most power your fuel gives.
• Place factories on the real map: link them to resource nodes (with miner tier and overclock) and to each other by belt, pipe, train, truck or drone.
• Wire power grids: power lines with Power Towers kept within the maximum span, geothermal generators on geysers, and each grid's MW generated against MW used.
• Draw infrastructure: conveyors, pipes, hypertubes, railways, truck roads and drone routes, plus stations.
• Plan trains: a station planner, a route planner per rail network, and a graphical train editor that shows how every train docks at every station, with expected deliveries and build costs.

Run it

Open index.html in a browser. No build step and no server needed. Or serve the folder:

python -m http.server 8000

Your plans are saved in the browser automatically. Use Export for backups.

Documentation

• User guide: how to use every part of the planner, with a keyboard/mouse reference and the list of estimates.
• Architecture and code design: modules, data flow, the saved-state model, algorithms (LP solver, floor-plan geometry, map rendering, rail simulation), data pipelines and how to extend it.
