So I built DocWebHub. It is a desktop app that shares one folder on your computer as a read-only website on the local network. People can preview Office documents and DWG files in the browser, and nothing is uploaded.

How it works

1. Pick a folder
2. The app gives you a URL like http://192.168.1.8:9102
3. Anyone on the same network opens that URL in a browser

There is no account, and it works offline. You can optionally set a password, bind to localhost only, or use a detected Tailscale address.

It runs on macOS, Windows, and Linux, including ARM. The viewers are packed into the download, so there is no extra runtime to install.

What you can open

• Word / Excel / PowerPoint, including older .doc / .xls / .ppt
• PDF, Markdown, images, audio, video, and source code
• DWG / DXF, with pan, zoom, and layers
• Save as PDF when you need it

If the folder has an index.html, that page is shown; otherwise you get a file list. It also works as a preview for a static site.

How this is different

Copyparty, miniserve, and python -m http.server are solid file servers, but they are not aimed at letting someone preview Office or DWG in the browser. LocalSend is great for transferring files, but it does not share a folder as a site.

DocWebHub is for handing someone a read-only link, without asking them to install software and without uploading the files.

Honest limitations

• The macOS build is not notarized yet, so the first launch needs a right-click and Open
• Windows may show SmartScreen
• The password restricts access; it does not encrypt the traffic

The project is dual-licensed, AGPL-3.0 and commercial.

Try it

• Site: https://docwebhub.app/
• Repository: https://github.com/0xChance/docwebhub
• First public release: v0.1.0

I would love feedback on the Office and DWG preview, and on the first-launch experience.
