Hexis is a native chat app where the server physically can't read your messages, the app uses around 50 MB of RAM and under 3% CPU, and there are no ads or trackers anywhere. Same servers, channels, DMs, and voice rooms you're used to. Built so it doesn't fight your machine.
Hexis isn't trying to reinvent group chat — just to ship the version of it your gut already expected: private, fast, and built for the long haul.
Hexis is end-to-end encrypted by architecture. The server routes encrypted blobs and has no keys — even if we wanted to read your chats, we couldn't. Not a privacy-policy promise. A property of the design.
Native Rust binary. No Electron, no Chromium, no Node. Around 50 MB of RAM at idle, under 3% CPU when nothing's happening, sub-second cold start. Your laptop's fan stays quiet. Your frames belong to your game.
Quantum-safe encryption today, so the messages you send in 2026 stay private when quantum computers arrive. Modern protocols. No legacy baggage. Built so you don't have to migrate again when the security floor moves.
The whole point of cloning the daily flow is that switching shouldn't require relearning anything. Same patterns. Same shortcuts. Same "drag a screenshot in and hit enter."
That's it. There's no second business model where we make money off your data on the side. Most of what we're doing differently is what we're not doing.
We're not an ad-supported app and we're never going to be.
We can't, even if we wanted to — we don't have the keys to read them.
No automatic message review, no flagged-keyword harvesting, no inbox crawler.
Chat is chat. No algorithmic timeline, no notifications-as-a-product, no addictive scroll.
Who you talk to is your business. Not data we collect, package, or sell.
You shouldn't need 500 MB of RAM to send a thumbs-up.
Same daily-driver experience. Different relationship with your machine and your data.
