The original
WhatsApp
An end-to-end encrypted messaging and calling app for phones, desktop computers and the web.
Replacements
Listings that take over the same core job as WhatsApp.
Signal
An end-to-end encrypted messenger for calls and chats on Android, iOS, Windows, macOS and Linux, run by a nonprofit.
Signal is open source under AGPL-3.0 and run by a nonprofit with no ads or tracking, still needing a phone number, while fewer contacts may use it.
Telegram Desktop
The official Telegram client for the desktop, with open source code and chats that are not end-to-end encrypted.
Telegram offers open source clients, cloud sync, large groups and bots, but ordinary chats are not end-to-end encrypted and the server is closed source.
Threema
Swiss encrypted messenger that works without a phone number or email.
Threema needs no phone number or email and has open source apps from a Swiss company, but requires a one-time purchase per platform.
Wire
End-to-end encrypted messaging, calls and file sharing for organisations.
Wire provides open source, end-to-end encrypted messaging and calls with a self-hostable server, focused on paid business plans with a limited free tier.
Session
An encrypted messenger with no phone number and no account, routed through an onion network.
Session drops the phone number for a random ID and routes messages through an onion network, though delivery is slower and contacts must exchange IDs.
SimpleX Chat
A messenger with no user identifiers at all, not even a random one, so there is no account to correlate.
SimpleX Chat uses no user identifiers at all and lets you choose or self-host relay servers, but contacts connect by sharing a link or QR code.
Molly
A security-hardened fork of Signal for Android with an encrypted local database and Tor support.
Molly is an Android-only hardened Signal fork with an encrypted local database and Google-free notifications, compatible with Signal contacts rather than WhatsApp ones.
Olvid
An end-to-end encrypted messenger that works without a phone number, email address or other personal data.
Olvid needs no phone number or address book access and offers end-to-end encryption on all major platforms, but contacts must install Olvid too.
Also worth comparing
These listings name WhatsApp as their own alternative, so the relationship runs both ways.
Snapchat
A messaging app built around photo and video Snaps, chat, Stories and camera Lenses.
WhatsApp focuses on end-to-end encrypted messaging and calls rather than Snaps, Lenses and feeds, and adds desktop apps, but still needs a phone number account.
Zalo
A Vietnamese messaging and calling app for phones and desktop computers, used by tens of millions.
WhatsApp adds end-to-end encrypted messages and calls and a web client, and is widely used internationally, though it is still proprietary and tied to a phone number.
