Compare Signal vs. SimpleX

Quick, straightforward, and secure—experience privacy that fits right in your pocket. Effortlessly send high-quality messages, whether they're group chats, texts, voice notes, videos, documents, or images, to anyone around the globe without incurring SMS or MMS charges. Every message and call made through Signal is protected with end-to-end encryption, meticulously designed to safeguard your communications. Your messages and calls remain private, as we have no access to them, nor does anyone else. Organize your chat history by using the disappearing messages feature, which allows you to select different intervals for each conversation, ensuring that everyone involved shares the same settings. Cherished memories can endure even if the words fade away. Signal prioritizes your needs, as it is an Open Source initiative backed by donations and grants, allowing it to focus on users instead of profit. With no advertisements, no affiliate marketing, and no invasive tracking, you can trust in technology that provides a quick, straightforward, and secure messaging experience. This is the way communication should be, empowering users while maintaining their privacy.

The innovative messaging platform stands out by eliminating user IDs entirely. Unlike other applications such as Signal, Matrix, Session, Briar, Jami, and Cwtch that rely on user identifiers, SimpleX takes a different route by not employing any form of user IDs or even random numbers, significantly enhancing user privacy. Users frequently inquire about how SimpleX manages message delivery without user identifiers. To facilitate message delivery, SimpleX employs temporary anonymous pairwise identifiers for message queues, which are unique to each connection, ensuring that no long-term identifiers are utilized. You have the flexibility to select which server(s) will handle your incoming messages, while your contacts will determine the servers used to send messages to them, meaning that each conversation may operate through two different servers. This unique structure effectively minimizes the risk of metadata leakage at the application level. In addition to this, users can further enhance their privacy and safeguard their IP addresses by routing their connections through Tor when accessing messaging servers. Only client devices retain user profiles, contacts, and group information, while messages are secured with a robust two-layer end-to-end encryption system. This approach not only prioritizes user privacy but also ensures a safer messaging experience overall.
