SimpleX Chat messenger

SimpleX Chat is a privacy-first messaging application that distinguishes itself from other platforms by being the first and only messenger that operates without unique user identifiers, such as phone numbers or email addresses. It was developed to provide a truly private and decentralized communication experience, utilizing a unique transport protocol that removes metadata from the communication layer.

The project was founded by Evgeny Poberezkin and is developed by SimpleX Chat Ltd, a company registered in the United Kingdom. Unlike centralized alternatives, SimpleX does not rely on a single server infrastructure; instead, it uses a network of servers that exchange messages using the SimpleX Messaging Protocol (SMP). The brand is currently owned and managed by its original founders, fueled by open-source community contributions and venture capital funding aimed at preserving digital privacy and sovereign communication.
