Description:
Arnon is a tiny open-source messenger for one-off end-to-end encrypted conversations. It runs entirely in the browser (PWA), with no app install, no account, and no phone number or email. Each room is just a random URL token.
How it works:
- ECDH (P-256) key exchange in the browser via Web Crypto API
- AES-256-GCM with a fresh IV per message
- Relay is a simple WebSocket server that only stores encrypted blobs in memory; nothing is written to disk
- Optional self-destruct timer that destroys the room on both sides when it expires
What it intentionally doesn’t do:
- No images, videos, or file sharing – just text and short voice notes (up to 30s), by design
- No contacts, groups, search, push notifications, analytics, or ads
Funding / governance:
- Free side project, no company, no investors, no monetization
- Single relay server at the moment; relay code is open-source and can be self-hosted
Happy to answer any questions or adjust the description to better fit the list. 🙂
