Free on Linux. Yours to build on.

BeepLoop is proprietary software with an open ecosystem.

Linux

Download it and use it. For anything: hobby tracks, teaching, your studio, records you sell. Commercial use included: no seat count, no revenue threshold, no phone-home, no account.

Everything you make is 100 % yours

Extensions, instrument presets, tunings, themes, .bloop projects, and the music itself; all of it is explicitly carved out of our license. You can release it under any license you want, GPL included, on any platform, and you can sell it.

These parts are open source

Apache-2.0

Extension API

The Python API your extensions import. Open on purpose: there is no doubt about your right to write, publish and sell them.

Apache-2.0

Format spec & MCP server

The full .bloop file format. Your projects stay readable by other tools — and by you, forever.

MIT

Example extensions

The three extensions shipped with the app. Copy-paste them, gut them, sell what you make. That's what they're for.

Documentation

Translate it, quote it, build a course on it. Credit us and you're done.

You may

  • Use BeepLoop on Linux for free, for any purpose, forever, including commercially.
  • Sell what you make with it — songs, samples, extensions, courses.
  • Write and sell extensions, under whatever license you choose.
  • Fork the open-source components and do as you please with them.
  • Share extensions with anyone, directly, right now — no store, no approval, no cut.

You may not

  • Redistribute the app itself — app stores, package repos, mirrors, pre-installed systems.
  • Run it on Windows or macOS without a commercial license.
  • Bypass the licensing or strip the copyright notices.
  • Call your thing “BeepLoop” — the name and logo aren't part of the deal.

Want to do one of these anyway — package it for your distro, ship it on a device, roll it out across a school? Just ask. Separate permission is cheap and the answer is usually yes.
