What is PaperPhone?

PaperPhone delivers a WeChat-style end-to-end encrypted chat app in JavaScript, blending BoxIM architecture with SimpleX Chat's security model for stateless per-message encryption via ECDH and XSalsa20-Poly1305. Users get secure 1:1 messaging, 2000-member groups, WebRTC P2P video/voice calls (with Mesh for small groups), social Moments feeds, public Timelines, auto-delete timers, and iOS PWA installs without certificates. Self-host it via Docker Compose or Zeabur for private comms with file sharing on Cloudflare R2.

Why is it gaining traction?

It packs WeChat's polish—stickers, friend tags, bidirectional privacy controls, multi-language auto-detect—into a zero-knowledge server that stores only ciphertext, ensuring forward secrecy without metadata leaks. One-command deploys, Web Push/OneSignal notifications, and TURN integration via Cloudflare make it dead simple for secure chats rivaling Signal or simplex, all in pure JS without native apps.

Who should use this?

Small teams or indie hackers needing a self-hosted alternative to Telegram for internal chats with social feeds and calls. Privacy advocates running communities who want WeChat UX minus data collection, or JS full-stack devs prototyping E2EE apps with PWA fallback for mobile.

Verdict

Grab it for proofs-of-concept if you're into JS-based paperphone or simplex clones—detailed multilingual docs and easy Docker setup shine, but 1.0% credibility from 46 stars signals early maturity; audit crypto and add tests before prod.
