NanoMQ vs Salesmsg: at a glance
What is NanoMQ?
A protocol-layer correctness pass, delivered largely by first-time contributors
0.25.6 is a bug-fix release the maintainer recommends to every user on an earlier tag, and its weight sits in NanoNNG rather than the broker: unsuccessful CONNACK negotiation is now rejected, Session Expiry Interval is accepted in CONNACK, pipes closed during the unlocked auth window are no longer registered, receive pipes unlink on session handoff, and a strict property checker guards against malformed input. Two potential security issues are patched, SCRAM handling hardened, and a workaround added for an NNG TLS idle bug. Four of the contributors are making their first commit to the project.
What is Salesmsg?
Salesmsg adds NPS surveys to SMS conversations and expands AI agent action repertoire
Salesmsg is building a closed-loop AI sales workflow across SMS and calling: agents contact prospects, handle replies, book meetings, escalate to humans with summaries, and now collect NPS feedback — all within a single conversation thread. The cadence is consistent: each release closes a gap in the end-to-end loop rather than shipping isolated features. The AI calling agent has especially matured, gaining intent-based tagging, post-call logging, and prompt-driven actions.

NanoMQ
6.3COMMS
A protocol-layer correctness pass, delivered largely by first-time contributors
◆ Current state
0.25.6 is a bug-fix release the maintainer recommends to every user on an earlier tag, and its weight sits in NanoNNG rather than the broker: unsuccessful CONNACK negotiation is now rejected, Session Expiry Interval is accepted in CONNACK, pipes closed during the unlocked auth window are no longer registered, receive pipes unlink on session handoff, and a strict property checker guards against malformed input. Two potential security issues are patched, SCRAM handling hardened, and a workaround added for an NNG TLS idle bug. Four of the contributors are making their first commit to the project.
◆ Where it's heading
The hardening campaign that began with fuzzing on the 0.24 line has moved up into MQTT protocol conformance — this release is dense with spec-edge handling and lifecycle races rather than crashes. The more interesting shift is social: after 0.25.5 traded architecture breadth for correctness depth, the protocol layer is now attracting outside contributors, with four newcomers landing fixes in NanoNNG in a single release. That is a different growth mode than the maintainer-driven cadence of the 0.24 line.
◆ Prediction
The 0.25 line looks set to continue on protocol conformance and session lifecycle correctness rather than new features. The SipHash client ID hashing question the maintainer raised in 0.25.2 is still open in these entries, with no resolution either way.
Salesmsg
5.0COMMS
Salesmsg adds NPS surveys to SMS conversations and expands AI agent action repertoire
◆ Current state
Salesmsg is building a closed-loop AI sales workflow across SMS and calling: agents contact prospects, handle replies, book meetings, escalate to humans with summaries, and now collect NPS feedback — all within a single conversation thread. The cadence is consistent: each release closes a gap in the end-to-end loop rather than shipping isolated features. The AI calling agent has especially matured, gaining intent-based tagging, post-call logging, and prompt-driven actions.
◆ Where it's heading
Salesmsg is systematically extending the AI agent's ability to take actions, not just respond — from routing by NPS score to auto-handling opt-outs to inserting calls-to-action directly in agent prompts. The addition of NPS surveys as a native product surface (not a third-party integration) signals a push toward owning the full customer feedback loop, not just the outreach side. CRM integrations, especially Salesforce, are getting deeper with each release.
◆ Prediction
The NPS/review data Salesmsg now collects natively will likely feed back into CRM sync (Salesforce first) and trigger AI-driven follow-up sequences. Expect the AI calling agent to gain more action types — likely calendar booking and CRM field updates — following the same pattern as the texting agent.
