About Kerbal Space Program
A physics-based space program sandbox: design rockets part by part and fly little green Kerbals into orbit and beyond.
Kerbal Space Program (2015) by Squad puts you in charge of a space agency run by small green Kerbals. You build rockets, planes and landers from hundreds of parts in the Vehicle Assembly Building, then try to reach orbit using real orbital mechanics — staging, delta-v, transfer burns and the occasional spectacular explosion.
Career and Science modes add contracts, funds and a technology tree, while Sandbox unlocks everything for free experimentation. This browser version is an independent web build; it needs a strong computer, and controls follow the original: WASD and QE to steer, Shift and Ctrl for throttle, Space to stage.

How to play Kerbal Space Program in your browser
- Press Play in browser — the game opens on ksp.ishotupa.school in a new tab.
- Wait while the game files load. The first start can take from a few seconds to a few minutes depending on your connection; later starts are faster because the browser caches the files.
- Click inside the game window so it captures the keyboard and mouse, then switch to fullscreen (F11 or the host's fullscreen button).
- Open the in-game settings to adjust controls, graphics and sound. Progress is normally kept in your browser storage, so don't clear site data if you want to keep your saves.
Kerbal Space Program controls
Default layout for this browser version. Keys can differ between builds, and most hosts let you rebind them in the settings. A USB or Bluetooth gamepad usually works too.
| Action | Key |

What to expect from the browser version
The browser version of Kerbal Space Program is an independent web project — a port, recompilation or fan remake — hosted on ksp.ishotupa.school. It is not an official release from Private Division, and MePlayable does not host any game files: we describe the game and link to the project.
Because the game runs inside a browser tab, some features of the 2015 original may be missing or work differently: online modes, cutscenes, saves, mods and graphics options depend on the build. If something doesn't work, check the host's own notes.
Requirements
A modern desktop browser — Chrome, Edge, Firefox, Opera or Safari 16+ — with WebAssembly and WebGL enabled, at least 4 GB of RAM and a stable connection for the first load. Hardware acceleration should be switched on in the browser settings.
If Kerbal Space Program doesn't start
- Black screen or endless loading — update the browser, enable hardware acceleration and reload the page with Ctrl+F5.
- No sound — click inside the game window: browsers only allow audio after you interact with the page.
- Lag or low FPS — close other heavy tabs and programs, then lower the resolution or graphics settings in the game.
- The site doesn't open — the host may be temporarily down or blocked in your region. Try again later or use another project link on this page.
