What we stand on, and under which licence.
Superiora Planner is proprietary software: the calculation engine, the application and the agent interfaces are ours and are not open source. They are built on open-source components, and this page names the principal ones with the licence each is distributed under. Every entry was read out of the dependency manifests of the build that ships, not from memory.

The engine
Rust crates.
The engine, the server, the control plane, the command line and the agent interface are Rust. These are the principal direct dependencies; the full resolved graph is larger and is available on request.

The application
JavaScript in the browser.
Studio and Spaces are a single-page application. These are its direct runtime dependencies; the build and test tooling below it is listed after.
| Component | What it does here | Licence |
|---|---|---|
| react · react-dom | The interface. | MIT |
| react-router-dom | Routing between the planes. | MIT |
| @tanstack/react-table | The grid’s table model. | MIT |
| @tanstack/react-virtual | Virtualised rows, so a large cube scrolls. | MIT |
| @dnd-kit/core · sortable · utilities | Dragging cards, columns and members. | MIT |
Build and test tooling
Not shipped to a browser, but part of how the product is made: vite, vitest, jsdom, eslint (with its JSX-a11y and React-hooks plugins), typescript-eslint, globals, @vitejs/plugin-react and @testing-library — all MIT; typescript and @playwright/test — Apache-2.0.
This website is built with vite (MIT); its only other build-time dependency is the video encoder noted below. It loads three typefaces — Space Grotesk, Inter and JetBrains Mono — from Google Fonts; each is published under the SIL Open Font License 1.1.
One build-time tool needs a legal decision rather than a line on a page: the screen recordings on this site are encoded with a packaged ffmpeg binary (@ffmpeg-installer/ffmpeg, declared LGPL-2.1, whose Linux binary package declares GPLv3). It is a development dependency of the website build, is not part of Superiora Planner and is not redistributed by us — but the exact obligations are [Owner: legal review of the ffmpeg build tool’s licence, and whether it stays in the toolchain].
03
The licences
What is in the set, and what is not.
The distinct licences across the direct dependencies above are: MIT, Apache-2.0, the dual MIT OR Apache-2.0, Unlicense OR MIT, and SIL OFL 1.1 for the typefaces.
No copyleft licence applies to anything Superiora Planner ships. Where a dependency offers a choice that includes a copyleft option, the permissive option is the one relied on. The one GPL-family item found anywhere is the website’s own build-time video encoder, noted above.
Copies of the licence texts, and the full resolved dependency graph with a version and a licence for every component, are available on request: hello@superiora.ai. Each component remains the property of its authors and is used under the terms of its own licence; nothing on this page grants you a licence to Superiora’s software, which stays proprietary.
