About SimpleX Chat

SimpleX Chat is a messaging app that connects contacts through invitations. Start with a test conversation and see how sharing an invitation, making a connection and managing it fit your normal messaging habits. The project documents its message relay model and clients, including mobile and desktop options. The lack of a public account identifier changes discovery, so it is a better fit for people who can exchange an invitation through another channel than for people looking up an established username. Privacy depends on the surrounding workflow too, including device access and how you verify who sent an invitation. Review the app's published security documentation for the scenarios that matter to you.
