A free, open, accessible controller for stream-deck-style control surfaces — built for the people the incumbents leave behind.
DeckLibre drives programmable control decks (starting with the Ulanzi D200X) without the closed, cloud-tethered vendor software they normally require. Four standing priorities, in order:
- Accessibility first — keyboard navigation, screen-reader labels, real contrast, each language shown in its own language. The biggest unforced gap across every competing product, and our North Star — not an afterthought.
- Simple by default — the everyday flow stays uncluttered; power lives behind an explicit Advanced unlock, so the common case never pays for the expert one.
- Fast — especially app and profile switching, where the closed tools lag.
- Choice — a prosumer tool that gives you knobs, not one hardcoded opinion.
Early development — the daemon's hardware layer is coming up against real devices. Not yet released.
DeckLibre is source-available under the Business Source License 1.1 (BSL) — not a permissive "do anything" license.
- Non-commercial use is free of charge. Use, modify, and share it for any purpose that isn't a commercial one.
- The license travels with the code. Every copy and every derivative stays under this same BSL — you may not relicense it, strip the terms, or pass it along for someone else's commercial use. "Free" here means free of charge for non-commercial use, not public domain and not "no rules."
- Commercial use requires a paid license. Selling DeckLibre, running it as a paid or hosted service, or bundling it with hardware offered for sale is commercial use — contact the maintainer for a commercial license.
- Each released version turns fully open source (Apache-2.0) four years after it is first published on GitHub.
The binding terms — including the exact definition of "Commercial Use" — are in the project's LICENSE (BSL 1.1); this summary does not replace it.
DeckLibre is part of a family of independent open-source projects that share a common foundation — the engineering doctrine, reference blueprints, and wire contracts maintained in CommonPractices. DeckLibre depends on that foundation; the foundation depends on nothing here.
