Slack raises the Marketplace bar back to ten installs while the agent platform consolidates.
A side-by-side editorial comparison of Salesmsg and SimpleX Chat — release velocity, themes, recent moves, and the top alternatives to consider.
Salesmsg is turning its AI agents from talkers into record-keepers that update the CRM themselves.
Salesmsg ships weekly, and the last two months have gone almost entirely into the AI calling and texting agents. August built the handoff path first — escalation to a human, transfer notifications, AI summaries of why a call moved — and then extended the agent's reach into the contact record with automatic post-call notes and intent-based tagging. Alongside the agent work it has bundled in two adjacent tools, Reviews in late July and NPS surveys in mid-August, both delivered over the SMS channel it already owns.
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.

Each agent release adds one more thing the agent can do without a person: first send an SMS, then transfer a call, now write the notes and apply the tags afterward. The KPI work shipping alongside it — Resolved, Transferred, Abandoned — suggests the constraint is no longer capability but customer trust that the agent handled the call correctly. Actions are converging on a single prompt-level interface, inserted by slash command, rather than separate configuration screens.
The next step in this line is letting the agent write to CRM fields rather than just notes and tags, most likely through the HubSpot and Salesforce integrations it already ships. Expect the outcome KPIs to gain per-agent comparison as more accounts run several agents at once.

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.
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.
