A native Rust chat app. Encrypted servers when you want them, post-quantum keys, and not a single ad or tracker.
// private beta · macOS + Windows · invite required
The server can't read a single word you send.
End-to-end encrypted DMs and server channels — double-ratchet and per-sender key encryption; the relay stores ciphertext it holds no keys to.
Native and quiet. No browser engine idling in the background.
Native Rust + Slint, no Electron — ~50 MB idle RAM, sub-second cold start, under 100 MB on disk.
Voice channels nobody overhears.
SFrame-encrypted Opus with per-speaker keys that rotate on membership changes — the relay forwards frames it can't decrypt.
Seriously low latency.
20 ms Opus frames in ~130-byte datagrams — one un-fragmented UDP send through a direct relay.
Encrypted to outlast quantum computers.
Every key handoff is sealed with ML-KEM-768 — traffic captured today stays sealed tomorrow.
No ads. No trackers. Nothing to sell.
No analytics, no tracking SDKs — and end-to-end encryption leaves nothing readable to mine.
Hexis is in private beta for macOS and Windows. Have an invite code? Grab the build. No code yet? Join the waitlist — we'll send one note when there's a seat, and nothing else.
