Pombo

Pombo is an open-source, peer-to-peer messaging and social media app, built on open infrastructure instead of a company's servers. Your account is a keypair on your device. No email, no phone number, no approval step. Direct messages are end-to-end encrypted and sealed, so not even the network learns who wrote. Channels can be open, password-protected, allow listed, token-gated or paid, and a paid channel's price goes straight to its owner. https://pombo.cc
