Show HN: Port – an open source, identifier-less, E2EE messaging app

Port is finally open source! We're a communication app that supports end-to-end encrypted direct chats, group chats and calling with an emphasis on user consent. Port replaces traditional permanent handles like phone numbers, usernames and email addresses with "Ports", allowing users to connect with peers without sharing any sensitive, permanent and personally identifying data. Using Ports you can decide how much access you grant others, from whether they're allowed to call you to if they can connect you with new people.
