Trust & data
No install, any modern browser
Cadre is a web application. There is nothing to download or update: open the page and model. It runs on current desktop browsers with WebAssembly support.
Offline-capable
The editor works fully offline. Modeling, boolean operations, measurement, import, and export all run locally in your browser with no network connection. The app installs as a Progressive Web App and caches itself for offline use.
Features that inherently need a network — accounts, cloud save, live collaboration, and AI review — are the only ones that require connectivity. When no cloud backend is configured, those surfaces are simply absent, and everything else still works.
Local-first, your model stays yours
Your work autosaves locally in your browser and restores when you reopen the tab. A model stays on your machine unless you deliberately save it to the cloud or share a link. Cadre does not require an account to model, measure, or export.
- Nothing is uploaded implicitly. Saving to the cloud and sharing a review link are explicit, opt-in actions.
- Your files are open formats. What you import and export are standard files you can open in other tools, so your geometry is never locked inside Cadre.
Formats & interop
| Direction | Formats |
|---|---|
| Import | STL (binary and ASCII), OBJ — auto-welded, with an open-edge report |
| Export | STL, OBJ, STEP (analytic surfaces), 3MF, glTF/GLB |
| Share | A review link, and a structured JSON export of any review for downstream tools |
STL, OBJ, 3MF, and glTF/GLB are triangle meshes. STEP export additionally carries true curved surfaces for the shapes that support them, so a cylinder exports as a cylinder rather than a facet approximation. See Export & interop for what each format preserves.
Data ownership, as a principle
You own your models. Cadre is a place to make and review them, not a vault that holds them hostage: every model can leave as an open file, and nothing leaves your browser unless you send it.
