Secure mini apps for chats

Play games or collaborate, privately.

Supported by

Private and peer-to-peer

🛡️ No tracking, no data leaks

Apps are sandboxed with zero internet access. They can never phone home, track you, or leak data. Verified by an independent security audit.

🌿 Works offline

Mini-apps run on the phones and devices of your chat partners only. Everyone can use mini apps while completely offline.

❤️ No platforms, no billionaires

Webxdc is an open community-specified mini app container format with a simple API. The same app works everywhere, no permissions needed.

🕊️ No servers needed

Apps are shared peer-to-peer through your chat. Realtime collaboration uses true peer-to-peer networking on chatmail clients.

Build your own mini app

If you can build a web page, you can build a mini app. Just zip your HTML, CSS and JavaScript into a .xdc file and share it in a chat. No hosting, no app stores, no user data to handle. The chat messenger takes care of delivery, encryption and identity so your code can focus entirely on the user experience.
