TwoPlacePaste

Share your clipboard across devices.

A self-hosted, end-to-end encrypted shared clipboard. Copy on one device, paste on another. The server relays ciphertext and never sees clipboard content.

What you get

Component	Stack	State
Relay server (tpp)	Go, Redis	Works. Relay, group/device registry, admin UI, blob GC.
Desktop app (tppdesktop)	Go + embedded React UI	Works on Windows and macOS. Tray icon, localhost web UI.
Go client core (pkg/tppclient)	Go	Works. All crypto and protocol; the desktop app is a shell around it.
Android app	React Native	In development.

Each group of devices shares one key that the server only ever holds wrapped to each device. Revoking a device rotates the key. Every entry expires after 24 hours. How it works →

Quick start

1. Run the relay with Docker Compose behind a TLS reverse proxy — guide.

2. Install the desktop app — Windows · macOS:

   curl -fsSL https://github.com/Mark7888/two-place-paste/releases/latest/download/install-macos.sh | sh
   

3. Create a group with a link from the relay's admin page, then add your other devices — guide.

Development

make build test lint      # every Go module
make help                 # everything else
