Zinutes

Zinutes is a simple P2P communication app. Once two peers connect, all messages go directly between them. The server never stores your messages or any sensitive data, only the minimum needed to verify your identity.

You can host your own backend and compile everything yourself. All the source code is available here. There's no central server (you can use any Zinutes server, or self-host your own).

Features

• E2E encrypted P2P messaging over WebRTC
• File sharing: images, video, and documents up to 100MB
• View-once messages
• Session management across multiple devices

Known limitations

• IP exposure: P2P connections reveal both peers' IP addresses (this is inherent to WebRTC)
• File size limit: 100MB max per file
• Session limit: Max 1 active session per account
• No message search: By design, for privacy reasons

Disclaimer: Some UI components were generated with the help of LLMs, mostly parts that don't interact with any important actions. The encryption, communication and the packet handling were made by hand. I don't work developing mobile apps, and originally this was developed using NativeWind, but due to some complications I had to migrate it to plain CSS, and for that I used an LLM. The same goes for some integrations with specific local libraries that interact with the phone API.
