SimpleX Chat review
A privacy-focused, open-source messenger that avoids user profile identifiers.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SimpleX Chat is an open-source encrypted messaging application for people who want private conversations without user profile identifiers. It supports end-to-end encrypted one-to-one and group messaging, file, image, and video sharing, voice messages, disappearing messages, and encrypted audio and video calls. Profiles, contacts, and message history are stored locally on users’ devices, while relay servers temporarily forward encrypted messages. Official apps are available for iOS, Android, Windows, macOS, and Linux, with support for self-hosted relay servers.
Its strongest advantage is breadth within a privacy-focused messenger. SimpleX Chat combines everyday text and media sharing with group conversations, calls, disappearing messages, incognito mode, and per-connection profile names. Portable encrypted database export and import adds a way to move stored data between supported environments. The open-source model also suits users who want to inspect or self-host parts of the service rather than rely only on a closed application. The platform range covers mobile, desktop, Linux, and self-hosted deployments.
The trade-off is device and administration flexibility. The same profile cannot be used simultaneously on multiple devices, while desktop linking is supported locally. Users selecting self-hosted relay servers may also need to handle additional technical administration. SimpleX Chat is a strong fit for privacy-focused individuals and groups who value encrypted communication, local data storage, open-source software, and avoiding user profile identifiers. It is less suitable for people who need the same profile active across multiple devices at once or who want a service designed around minimal technical involvement.
