Onym Messenger vs Vutalk

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.

Vutalk is an end-to-end encrypted messenger for people who would rather not hand over a phone number or an email address. You create an account without either. The app gives you an Account ID and a recovery key, and nothing else is needed. Other people reach you through the username you pick, or the QR code that goes with it. Your address book is never uploaded. Messages, calls, and files are encrypted on your device before they leave it, and the keys stay on your devices. Nobody in between can read them, and neither can we. FEATURES No number, no email — Create an account with no phone number and no email address. Keep your Account ID and recovery key: they are how you get back in. Username and QR code — Share a username, or let someone scan your code. Your contacts are never uploaded or matched against our servers. Encrypted messaging — One-to-one and group conversations, end-to-end encrypted by default. Voice and video calls — Encrypted calls, one-to-one and in groups, with voice or video. Photos, video, and files — Send images, videos, documents, and voice messages through the same encrypted channel. Wallet — Receive, send, and view history from Settings. The keys stay on your device. Disappearing messages — Choose how long a conversation keeps its history, from seconds to weeks. Free, with nothing to buy — No subscriptions, no in-app purchases, and no advertising. Modern cryptography — Key agreement uses X3DH, and every message advances a Double Ratchet, so earlier messages stay protected even if a device is compromised later. Accounts created with an email address in an earlier version keep signing in with that address.
