Getting started

Career provides missions and unlocks parts as you progress. Sandbox opens the parts catalog, multiplayer and interstellar travel. Choose full scale or a smaller 1:10 or 1:20 system.
Build or load a craft
Use a preset, build from scratch or download a player design from the Community Hangar.
Launch
Start with a short flight. The in-game guide explains the controls, navigation and staging. For help or bug reports, join the Discord.
Download questions
Is Rocket Foundry free?
The beta is free to download and play on Windows, macOS, Linux, Android and iOS.
Is there a Mac version?
Yes. The Mac download requires Apple Silicon (M1 or newer). Intel Macs are no longer supported. It is signed and notarized by Apple, so it opens like any other app: unzip it and open Rocket Foundry.
Is the game finished?
No. It is an independent game in active development. Features, balance and performance change between builds, and download links point to the latest available build for each platform.
Do I have to play at full scale?
No. Worlds use the real solar system at full scale by default, and you can choose a compact 1:10 or 1:20 world instead. Your rockets stay the same size and surface gravity stays the same.
Can I play with friends?
Yes. Host one of your Sandbox worlds from the game and share the room code, or run the free dedicated server on Linux.
Can I make things other than rockets?
Yes. The same builder makes planes, rovers, walkers, boats and stations, and the in-game editors create new parts, planets and whole star systems.
Where are my saves?
On your own device, as plain files you can back up or share. The in-game guide (MORE, then Guide, then Your files) shows where they are on each platform.
How is my data handled?
Optional analytics needs your permission, and you can change your choice later. Read the privacy policy for the game, the website and the Community Hangar.
