Signal Desktop vs SimpleX Chat: at a glance
What is Signal Desktop?
Signal is quietly rebuilding group governance while polls and pins push into everyday chats
The desktop beta line is shipping a steady run of user-facing social features: polls extended to one-to-one chats, admin deletion of recent group messages, an explicit End Group action, disappearing call events, and reorderable sticker packs. Each release carries one or two concrete changes rather than a bundle. Pinned chats also moved from 4 to 10.
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.

Signal is quietly rebuilding group governance while polls and pins push into everyday chats
◆ Current state
The desktop beta line is shipping a steady run of user-facing social features: polls extended to one-to-one chats, admin deletion of recent group messages, an explicit End Group action, disappearing call events, and reorderable sticker packs. Each release carries one or two concrete changes rather than a bundle. Pinned chats also moved from 4 to 10.
◆ Where it's heading
Two threads run through the window. One is group administration — admins gained message deletion and a way to formally close a group, turning groups from open-ended threads into objects with a lifecycle. The other is bringing lightweight social mechanics from group chats down into individual ones. Both extend the surface without touching Signal's privacy model.
◆ Prediction
Expect the group-lifecycle work to continue with more admin controls, and for the features currently landing in desktop beta to promote into the stable line on the same weekly-to-biweekly rhythm.

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.
