Jami vs SimpleX Chat
Side-by-side comparison of features, pricing, ratings, and alternatives.
Jami is a free, open-source communication platform backed by the Free Software Foundation as a GNU project. It provides instant messaging, audio/video calls, group chats, video conferencing, and screen sharing, all built on a fully peer-to-peer architecture that doesn't rely on central servers to relay communication. Because Jami is serverless and end-to-end encrypted with perfect forward secrecy, it requires no personal information to create an account and can even work over a local network without internet access. It's available on Linux, Windows, macOS, iOS, Android, and Android TV, and includes an extension platform and SIP client support for added flexibility.
SimpleX Chat is an open-source, end-to-end encrypted messenger built around a network design with no persistent user identifiers of any kind, not even random ones. Messages are relayed through servers that see only noise, so there is no phone number, username, or account ID for anyone, including SimpleX, to tie back to a person. The app supports one-to-one and group chats, audio and video calls, file transfer, and multiple chat profiles, and it can run on self-hosted servers for organizations that want full control over their infrastructure. Its protocol and clients are fully open source and have been independently security-audited by Trail of Bits.
