Step 1 · Place

Place your app.

Start with one HTML file. Add a project folder only when the app also uses separate CSS, JavaScript, images, fonts, or media.

Start HTML file

My app also has CSS, JavaScript, images, or other files

Optional: first choose the start HTML above, then choose the whole folder that contains that same file at its top level.

Project folder optional

Up to 40 additional files and 5 MB for the complete project, including the start HTML.

No project folder selected. MosHub will upload the single HTML file.

App name optional · filename used if empty Short description optional

Who can find and open this app?Choose explicitly. This controls discovery, not ownership or copyright.

PublicAppears in Explore. Anyone can open, try, download, and copy it. Link onlyDoes not appear in Explore. Anyone with the full link can open, download, and copy it. They can also try it directly in MosHub. Link only is not private. PrivateNot available yetRestricted access for selected people is not part of this alpha. Do not upload sensitive data.

No account is created. You receive one secret management link after upload.

What works in the preview?

The start HTML remains limited to 1.5 MB. Inline CSS and JavaScript work. With a project folder, relative CSS, JavaScript, images, fonts, audio, and video can work too. External network and fetch requests, forms, workers, and persistent browser storage remain restricted. An app can still replace its own preview frame; the MosHub page remains outside it. Browser isolation reduces risk but is not a guarantee.

You will review and save your app and management links next.
