SimpleX Chat
Self-HostedPrivacy-first, serverless end-to-end encrypted chat with no user IDs
Overview
SimpleX Chat is a privacy-centric communication app that eliminates user IDs (no phone numbers/emails) for anonymous, secure interactions. It uses end-to-end encryption for all messages, group chats, file sharing, and voice notes. Users can self-host their own relays to control data flow or use public ones. Cross-platform (mobile/desktop) and decentralized, it ensures no single point of failure, making it ideal for privacy-conscious users seeking an alternative to mainstream chat apps.
Key Features
- No user IDs (no phone/email required)
- End-to-end encrypted group chats & file sharing
- Self-hostable relays for data sovereignty
Frequently Asked Questions
? Is SimpleX Chat easy to install for regular users?
Installing the mobile or desktop app is straightforward (available on App Store, Google Play, and GitHub). Self-hosting relays requires basic server knowledge (Docker setup or manual configuration with documentation).
? How does SimpleX Chat compare to Signal in privacy?
SimpleX offers stronger anonymity (no phone number required) compared to Signal's phone-based user IDs. Both use end-to-end encryption, but SimpleX's decentralized relays provide additional data sovereignty options.
? Is SimpleX Chat completely free?
Yes—SimpleX Chat is open source (MIT license) with no paid tiers. End users pay nothing, and self-hosting relays only incurs server hosting costs if you choose to run your own.
