Open-source licenses

Last updated October 6, 2026 · v1.1

Fuel Relay is built on open-source software. Every package below ships inside the mobile app or the admin site, with the license it is distributed under and its copyright notice.

About this page

This list is generated from the production dependencies that actually ship, so it stays accurate as the apps change rather than drifting from a hand-kept list. It covers 949 packages across 21 license types.

Each entry names the package, the version we ship, and the copyright holder where the package states one. Full license texts are distributed with each package and are available from its own repository. Nothing here limits your rights under those licenses.

Questions about attribution, or a correction to this list, can go to our contact page.

Fonts, icons and images

  • Geist Sans and Geist Mono, the website’s typefaces, copyright 2023 Vercel, in collaboration with basement.studio, used under the SIL Open Font License 1.1. We serve our own copy of the font files; the license travels with them at fuelrelay.net/fonts/LICENSE.txt.
  • Icons on the website and in the dashboard come from Lucide (ISC License), listed below as lucide-react.
  • Screenshots and pictures. Every screenshot on this site is of Fuel Relay itself, showing a made-up demo company, and the logo is our own. We use no stock photos and no images licensed from anyone else.
