Open source

DomiSol is built on the shoulders of giants.

None of this would exist without the open-source ecosystem. Here's everything we use, with thanks. If we've missed your project, please email us — we'll fix it.

Our own code

DomiSol is a closed-source product today. As we stabilize, we intend to open-source pieces that are useful on their own — the solfa/jianpu rendering engine, the Zod schemas, the score data model. They'll land on github.com/domisol under MIT.
