A simple web app that I created to use as a shared clipboard and file-share service.
❗Disclaimer: partially vibe-coded.
The app uses sockets to make sure the data is updated in real time.
It uses basic auth and has some other security features:
- Allows a maximum of 5 connected users at a time (configurable).
- Users are disconnected from the server after 2 minutes of inactivity (configurable).
- The clipboard is capped at 1MB capacity (configurable).
- File uploads are capped to 10GB total capacity (configurable).
