PlyLoom / Download
One file. Ready to go offline.
Download the app, open it in your browser and save your first map.
- Save PlyLoom.html to your computer. If it opens in the browser, use Save link as… instead.
- Open the file in a modern browser. No connection to the website is needed after downloading.
- Choose Project → Download .plyloom to save your map. The HTML contains the app, not your edits.
Browser autosave is a convenience, not a backup. A different browser, moving the HTML or clearing storage can hide your previous save. Export .plyloom regularly.
What does a map file contain?
Entities, text, relations, sheets, positions, attributes and saved views. Keep the native .plyloom file; Canvas and draw.io exports can simplify the map.
Do I need to pay?
The app is free. Optional support does not unlock hidden features and is never required to download.
Terms of use
PlyLoom is free for personal and commercial work, with no account and no payment. You may keep the application file and pass it on unchanged. Selling it, bundling it into a paid product or publishing a modified version requires the author’s permission. Maps you create are yours: the app has no server component and never sends them anywhere. No warranty is given. The bundled open-source libraries keep their own licences: full text.
