Keet vs ZIØN

Keet is the chat app that knows nothing about you — a truly peer-to-peer way to connect. Your messages, files, and calls are shared directly between your devices, never through corporate servers. No central databases. No data mining. No one in the middle. Whether you’re chatting with friends, family, or your team, Keet keeps your conversations private, fast, and completely under your control. TRUE PRIVACY, BY DESIGN No servers. No data stored in the cloud. Messages and calls are end-to-end encrypted and travel only between participants. Not even Keet can access your conversations. FAST, DIRECT CONNECTIONS P2P technology connects you device-to-device, reducing lag and server dependency. Built on next-generation distributed communication protocols. MODERN CHAT FEATURES 1-to-1 and group conversations. HD audio and video calls. File sharing with direct device transfer. Cross-platform support on desktop and mobile. WHY KEET IS DIFFERENT Other apps route your messages through remote data centers. Keet doesn’t. Your chats never touch a server - they stay between you and the people you trust. Your conversations belong to you. Keet just makes them happen - privately, instantly, peer-to-peer. Download Keet and take back control of your communication.

ZIØN is a peer-to-peer, end-to-end encrypted messenger built on one principle: your conversations belong to you and your contact — no accounts, no cloud, no message database. HOW YOUR MESSAGES TRAVEL • On the same network, ZIØN connects your devices directly, device to device. Nothing leaves your local network. • Across different networks, messages are carried by a minimal relay we operate that only forwards already-encrypted bytes. It is zero-knowledge by design: it cannot read your messages, your contacts, or any content — and neither can we. • Optional WAN mode (OFF by default): when you enable it, ZIØN can also open a direct device-to-device connection across the internet via UDP hole punching. Only then does the app contact public IP-discovery services (ipify, ifconfig.me, icanhazip, checkip.amazonaws) to learn its own address for NAT traversal. There are no ZIØN accounts and no cloud storage of your messages. The relay never holds anything it can decrypt.
