Third-party licences — Cutmoor
Cutmoor is built on open-source software. The browser does the heavy lifting, and several of those components carry obligations that are worth stating plainly.
The list below covers the components that are distributed to visitors as part of the site, plus the libraries used to build it. Full licence texts are available at the linked upstream projects and in the repository's THIRD_PARTY_NOTICES.md.
Last updated 2026-11-11FFmpeg and ffmpeg.wasm
Video decoding and encoding use FFmpeg, compiled to WebAssembly and delivered by the ffmpeg.wasm project. The @ffmpeg/core build used by Cutmoor is licensed under the GNU General Public License version 2 or later (GPL-2.0-or-later).
The corresponding source code is available from the FFmpeg project and the ffmpeg.wasm repository, including the scripts used to build the WebAssembly core. If you deploy a modified version of the core, you are responsible for providing the corresponding source under the GPL.
- FFmpeg — GPL-2.0-or-later for this build.
- ffmpeg.wasm — build and packaging source.
- @ffmpeg/ffmpeg and @ffmpeg/util — MIT.
HEIC decoding
The HEIC converter uses the heic-to library, which bundles a WebAssembly build of libheif and the libde265 decoder. These components are licensed under the GNU Lesser General Public License version 3 (LGPL-3.0).
The decoder is loaded lazily, only when a HEIC file is selected, and runs entirely in the browser. Cutmoor does not modify the library. The upstream source is linked below so the corresponding source can be obtained.
- heic-to by Hopper Gee — LGPL-3.0.
- libheif — LGPL-3.0.
- libde265 — LGPL-3.0.
Interface and build libraries
The interface is built with React and React Router under the MIT licence. Icons come from Lucide under the ISC licence. The site is built with Vite under the MIT licence.
- React and React DOM — MIT.
- React Router — MIT.
- Lucide — ISC.
- Vite — MIT.
Fonts
Geist and Geist Mono are served through Fontsource and are licensed under the SIL Open Font License 1.1. The fonts are self-hosted with the site, not fetched from a third-party font service.
- Geist — OFL-1.1.
- Geist Mono — OFL-1.1.
- Fontsource — MIT packaging.
No warranty
These components are provided as-is, without warranty of any kind. The licence texts control the rights and obligations that apply to each component; this page is a summary, not a substitute for those texts.
If you deploy Cutmoor commercially, review the GPL and LGPL obligations with your own counsel and keep the linked source and notices available to visitors.
