Live-typing encrypted chat for Windows — no accounts
2 followers
Free, open-source Windows chat where you watch every keystroke appear live — end-to-end encrypted, no accounts, nothing stored. Share a 6-char code to connect. Both sides get fresh ECDH P-256 keys each session. Messages are AES-256-GCM locked before leaving your machine. Includes file transfer, shared whiteboard, Walk Web (push URLs), themes, and profiles. Requires the SemaBuzz-Relay — single binary, ~10 MB, MIT licensed.
Hey PH! I grew up on PowWow, ICQ, and MSN Messenger — there was something magical about that era of direct, personal chat that modern apps have completely lost. I built SemaBuzz to bring that feeling back.
You'll find a lot of the classics: URL Walk, a shared whiteboard, file transfer, and rich status changes with custom status messages — things PowWow and ICQ fans will recognize instantly.
Then we added our own spin: every session generates fresh encryption keys via token-based E2E chat, with a private relay that literally cannot read your messages. And the live-typing preview — that flowing filament line showing characters as they're typed — is our love letter to what made those old programs feel so alive.
Fully open-source (AGPL-3.0). Would love to hear from anyone else who misses that era. 👾
