Web Fusée Launcher

Fusee Launcher ported to JavaScript using WebUSB.

Source can be found on GitHub (or by hitting view source, there is no backend!). Ported from fusee-launcher. Thanks to ktemkin and ReSwitched for Fusée Gelée and a ton of other things!


  1. Put the Switch in RCM, and connect it to your device.
  2. Select either the example payload, or upload one.
  3. Press 'Do the thing!'
  4. On the consent screen that appears, select 'APX' and hit confirm.
  5. If all goes well, the payload will launch!
