Hexis is a chat app where the server literally can't read your messages. Same servers, channels, DMs, and voice rooms you're used to — minus the parts that read your chat to sell ads or train models. Your group chats stay yours.
Three things that should be table stakes in 2026, and somehow still aren't. Hexis isn't trying to reinvent group chat — just to ship the version of it your gut already expected.
The server physically can't read your messages — it has no keys, no decryption ability, no "trust and safety" inbox crawler. Not a privacy-policy promise. A property of the architecture.
Native binary. No Electron, no Chromium, no Node. Tens of megabytes of RAM at idle, sub-second cold start, no background CPU when nothing's happening. 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 Discord's daily flow is that switching shouldn't require relearning anything. Same patterns. Same shortcuts. Same "drag a screenshot into the channel and hit enter."
Most of what we're doing differently is what we're not doing. Negative space sells.
We're not an ad-supported app and we're never going to be. You're paying for chat, not being sold.
We can't, even if we wanted to — we don't have the keys to read them.
No automatic message review, no "trust and safety" inbox crawler, no flagged-keyword harvesting.
Chat is chat. No algorithmic timeline, no notifications-as-a-product, no addictive scroll.
Who you talk to is your business. The server doesn't have a complete picture and we couldn't sell it if we tried.
You shouldn't need 500 MB of RAM to send a thumbs-up.
Same daily-driver experience. Different relationship with your data.
