Onym Messenger vs Haven

Onym is a private messenger built on one idea: your conversations are yours. END-TO-END ENCRYPTED Only the people in your group can read what's sent. Onym's servers never see your messages. NO PHONE NUMBER, NO EMAIL Your identity is a cryptographic key you own — not your contact info. Create one in seconds, and make as many as you like. NO CENTRAL SERVER Group membership is anchored on the Stellar network, not owned by us. There's no company account that can lock you out. START A CHAT WITH ONE LINK Spin up an encrypted group and share a single invite link. People join later without exchanging any keys. BRING YOUR OWN INFRASTRUCTURE Onym carries messages and media over open Nostr relays and Blossom servers. Use the defaults, or point the app at your own instances for maximum privacy. MULTIPLE IDENTITIES Keep contacts and chats cleanly separated. Switch between identities with a tap. YOU HOLD THE KEYS A recovery phrase restores your identity on a new device. Lose it and no one — including us — can recover it. Onym doesn't ask who you are. No accounts, no profiles, no tracking, no ads. Just private conversations you control. Built by people who think privacy is a right.

Haven is private chat for communities that run their own server. Your messages live on a box you control, not on someone else's cloud, and direct messages are end-to-end encrypted so even the server can't read them. END-TO-END ENCRYPTED • Direct messages and group DMs are encrypted on your device (ECDH P-256, HKDF-SHA256, AES-256-GCM) • Pictures and files in encrypted conversations are encrypted too • Group messages are signed, so you can tell who really sent them • Optional encrypted key backup restores your keys with your password CHAT THE WAY YOUR GROUP DOES • Text channels, private channels, DMs and group DMs • Threads, replies, quotes, reactions, custom emoji and stickers • Forums with topics and tags, polls, pinned messages and search • Pictures, video, files and GIFs • Markdown, tables, spoilers and code blocks • Official messages that make staff announcements stand out VOICE AND VIDEO • Drop-in voice channels • Video and screen sharing • Push notifications for mentions and DMs YOUR DATA, YOUR RULES • Delete your own messages, all of them or only those older than a day, a week, a month or a year • Auto-delete your messages after a set time • Export your data as one file • Block people, and see and sign out every device on your account MAKE IT YOURS Dozens of themes, icon packs, adjustable text size and accessibility settings.
