Build for Capsule
Capsule is an open instrument-platform. Build synth engines, effects and tools — and ship them to every LAB. You can start before the hardware ships.
The pipeline
Write a plugin, build it offline, hear it in the simulator, ship it to every LAB. No hardware, no waiting — tap a step.
The toolkit
Develop entirely on your computer with a free, permissive SDK — then ship to every LAB. You don’t need a device to start.
A free, permissive SDK with a real API and full docs. Develop offline on macOS, Windows or Linux, then ship signed plugins to the Capsule ecosystem.
A desktop simulator builds and plays your plugin on your computer — no device needed. Want to feel the platform first? Play Capsule in your browser.
The plan
We’re opening the tools ahead of broad shipping, so there’s a real ecosystem on day one.
Tell us what you’d build. We’re recruiting a first cohort now.
Get the desktop SDK and build offline, with the simulator — before hardware.
We seed units to active developers. Every LAB is a devkit.
Your plugin reaches every LAB owner, day one and beyond.
From the community
One SDK, every kind of instrument. Real projects from our first developers will live here. (Showcase coming as the first cohort ships.)
Developer updates
A separate, low-volume list just for builders — SDK access, docs, and developer news. Not the consumer mailing list.
A separate developer list. We email occasional SDK and developer news; unsubscribe any time.
✓ You’re on the developer list — we’ll send SDK access first.
