Acknowledgements & third-party licenses

Cadence is open-source software licensed under the MIT License. It also builds on third-party open-source projects that it redistributes as part of the app. This page credits those projects and points to their licenses. The authoritative, complete list — with the full license texts — lives in THIRD-PARTY-NOTICES.md at the root of the repository.

Landing site design reference

The landing site’s composition and motion language adapt the MIT-licensed PowerAI Astro reference by Sitepins. Cadence keeps its own brand, product copy, media, fonts, and deployment model. The complete copyright and permission notice is preserved in THIRD-PARTY-NOTICES.md.

Landing site browser runtime

The deployed landing page redistributes browser code from Astro’s island runtime and React renderer, React and React DOM, Scheduler, Motion and its Framer Motion packages. Their exact versions, dependency graph, copyright notices, and complete license terms are preserved in the landing site browser runtime notice. Build-only packages such as Tailwind CSS and Vite plugins are not shipped to the browser and are excluded from that runtime notice.

MP3 export — the LAME encoder

Cadence’s MP3 export is powered by the LAME MP3 encoder, via @breezystack/lamejs (version 1.2.7) — a pure-JavaScript port of LAME. It is used unmodified and is loaded on demand, only when you export an MP3.

License: GNU Lesser General Public License, version 3 or later (LGPL-3.0-or-later).
LAME project: https://lame.sourceforge.io/
Package: https://www.npmjs.com/package/@breezystack/lamejs — a fork of the original zhuker/lamejs.

With thanks to the LAME project and its contributors for the encoder that makes MP3 export possible.
