Dendrite vs SimpleX Chat: at a glance
What is Dendrite?
A forked, relicensed Dendrite spent its first year catching up on Matrix protocol and security debt
The window opens with the first release after forking from matrix-org/dendrite under AGPLv3, which fixed long-standing state-reset bugs and added I2P and Onion listening. What follows is a security release closing a server-side request forgery vulnerability, then a release adding room version 12 support and two MSC implementations, and finally two quick patches for unresponsiveness, v12 room joins and malformed PDUs blocking whole transactions.
What is SimpleX Chat?
The no-identifier messenger is building public channels — and has to invent trust from scratch
SimpleX Chat is deep in a v7.0 beta cycle, six betas in, with the stable armv7a tag now cut. The release is dominated by channels: broadcast surfaces with subscribers, contributor and moderator roles, searchable subscriber lists, and CLI access. Alongside them sits SimpleX names — registerable, resolvable names for channels and businesses — and per-server role controls that let self-hosters run a relay that handles only message reception, private routing, or name resolution.

◆ Current state
The window opens with the first release after forking from matrix-org/dendrite under AGPLv3, which fixed long-standing state-reset bugs and added I2P and Onion listening. What follows is a security release closing a server-side request forgery vulnerability, then a release adding room version 12 support and two MSC implementations, and finally two quick patches for unresponsiveness, v12 room joins and malformed PDUs blocking whole transactions.
◆ Where it's heading
This is a fork proving it can carry a homeserver. The order is telling: license and state correctness first, then a CVE, then protocol currency with room version 12, then the operational bugs that surface once people actually run it. Several fixes carry outside contributor credits, which is the fork's clearest sign of life.
◆ Prediction
Expect continued protocol catch-up on newer MSCs and room versions plus operational fixes, since federation compatibility is the constraint that sets this project's agenda.

The no-identifier messenger is building public channels — and has to invent trust from scratch
◆ Current state
SimpleX Chat is deep in a v7.0 beta cycle, six betas in, with the stable armv7a tag now cut. The release is dominated by channels: broadcast surfaces with subscribers, contributor and moderator roles, searchable subscriber lists, and CLI access. Alongside them sits SimpleX names — registerable, resolvable names for channels and businesses — and per-server role controls that let self-hosters run a relay that handles only message reception, private routing, or name resolution.
◆ Where it's heading
This is the hardest problem the project has taken on. SimpleX's premise is that users have no identifiers at all, and public channels need exactly the opposite: a stable name people can find and an author they can verify. The answer taking shape is cryptographic rather than account-based — message signing, member security-code verification, and name resolution run as an opt-in server function. The betas since then have shifted from adding channel features to hardening the role model, rejecting forwards from unexpected admins and locking relay-role assignment.
◆ Prediction
A 7.0 stable release looks imminent given the non-beta tag, with message signing held back for 7.1 as the notes state. Expect the next cycle to turn signing on and continue tightening who can act as a relay or admin inside a channel.
