Alter Messenger vs Viper Messenger

Securely chat with friends, without the concern of prying eyes. There are multiple layers of privacy, including screenshot detection, selecting a different username for each chat, and more. More features coming soon.

Viper is a privacy-first messenger that works over the internet, directly between phones, and over Bluetooth when there's no internet at all. No phone number. No email. Your identity is a cryptographic key, and that key is also your TON address. Every message is end-to-end encrypted, whichever way it travels. # FEATURES • Route: choose how your messages travel • Bluetooth messaging and People Nearby • Voice and video messages • Unlimited P2P file sharing • Private reactions, hidden from anyone in between • Find people by .ton domain instead of long addresses • Built on TON # ROUTE You choose the path, and the balance of reach, speed and privacy: • Relay: works anywhere and holds encrypted messages until the recipient comes online. • Direct P2P: phone to phone over TON, faster and with nothing stored in between. • Bluetooth: for people nearby when there's no internet or cell signal. # BLUETOOTH & PEOPLE NEARBY Meet in person, keep talking after. People Nearby shows Viper users around you with approximate distance, and every contact proves they own their key. Messages, voice and video messages, and files work in a basement, on a festival field, in the metro. Interrupted transfers resume where they stopped. When you part ways, the chat moves to a direct TON connection, and you can send that person TON later. Your Bluetooth signal reveals only that a Viper user is nearby. Visibility and Show My Distance can be turned off at any time. # UNLIMITED P2P FILE SHARING Files go directly between devices, never through Viper servers. No subscriptions, no storage quotas, no size limits. Both peers need to be online during the transfer. # VIPER PRO An optional monthly subscription for an even quieter presence: • Anonymity: strangers can't find you, probe you or fill your chat list. Existing chats keep working. • Hide Online Status. • Extended Invisibility: no read receipts, no typing indicator. • Files over 2 GB via relay. • Encrypted chat backup.
