Hey HN! I'm one of the developers of Termly.

  Problem: I love using Claude Code for development, but being chained to my laptop all day wasn't working. SSH + terminal emulators
  felt clunky for interactive AI coding sessions.

  Solution: Built a WebSocket relay that mirrors your AI coding session to mobile with zero-knowledge E2E encryption.

  How it works:
  1. npm install -g @termly-dev/cli
  2. termly start (wraps your AI tool)
  3. Scan QR code with mobile app
  4. Your session syncs in real-time, encrypted end-to-end

  Tech stack:
  • Open source CLI (MIT licensed) - inspect the code yourself
  • WebSocket relay server
  • AES-256-GCM + Diffie-Hellman key exchange
  • React Native mobile apps (iOS live, Android in beta)
  • Zero-knowledge architecture - server never sees plaintext

  Why not just SSH?
  • Optimized for AI workflows (session catchup, batch sync)
  • Voice input for mobile prompting
  • Better UX than traditional terminal emulators
  • Automatic reconnection handling
  • Free to use

  Open source CLI:
  The CLI and all client-side encryption code is MIT licensed. You can verify the zero-knowledge architecture yourself.

  Current status:
  • iOS app live on App Store
  • Android beta launching this month
  • Works with Claude Code, Cursor, Aider, and other terminal-based AI tools

  Would love feedback from HN! What features would make this more useful for your workflow?
