Fonoster vs NanoMQ: at a glance
What is Fonoster?
Fonoster now cleans up deleted workspaces and stops exposing stored secrets.
Fonoster ships minor versions almost daily. v0.51 to v0.53 added Anthropic, Google and Groq models, TTS voice choice and one-switch call recording. From November 10, v0.54 to v0.56 added branded emails, legal pages, webhook event lookups and API key rotation, and v0.57 returns secret values only to API keys, cancels a deleted user's plan, and ends a deleted workspace's calls and resources.
What is NanoMQ?
NanoMQ follows its hardening run by moving onto Zephyr microcontrollers.
NanoMQ 0.25.7, published on 21 October and described as a beta, runs on the Zephyr RTOS after platform-layer work on memory allocation for microkernel environments. It also pushes the multi-tenant mountpoint logic down into the transport layer, gives each bridge its own cache with REST control, lets operators kick clients by ID over the API, and supports PKCS#11 hardware keys with certificate-to-username mapping. 0.25.6 in August had been a protocol-conformance and auth-race fix release.

Fonoster
7.5COMMS
Fonoster now cleans up deleted workspaces and stops exposing stored secrets.
◆ Current state
Fonoster ships minor versions almost daily. v0.51 to v0.53 added Anthropic, Google and Groq models, TTS voice choice and one-switch call recording. From November 10, v0.54 to v0.56 added branded emails, legal pages, webhook event lookups and API key rotation, and v0.57 returns secret values only to API keys, cancels a deleted user's plan, and ends a deleted workspace's calls and resources.
◆ Where it's heading
After a quick run of voice-AI options, Fonoster has turned to what a hosted service needs before paying customers rely on it: legal pages, billing correctness, webhook debugging and account deletion that actually removes data. The cadence stays daily and the changes stay incremental.
◆ Prediction
More account and billing lifecycle work is likely next, since v0.57 adds a billing test case and deletion rules in the same release.
NanoMQ
2.5COMMS
NanoMQ follows its hardening run by moving onto Zephyr microcontrollers.
◆ Current state
NanoMQ 0.25.7, published on 21 October and described as a beta, runs on the Zephyr RTOS after platform-layer work on memory allocation for microkernel environments. It also pushes the multi-tenant mountpoint logic down into the transport layer, gives each bridge its own cache with REST control, lets operators kick clients by ID over the API, and supports PKCS#11 hardware keys with certificate-to-username mapping. 0.25.6 in August had been a protocol-conformance and auth-race fix release.
◆ Where it's heading
0.25.5 dropped MIPS and ARMel binaries to concentrate on correctness, and 0.25.6 spent that effort on MQTT conformance. 0.25.7 points the broker at smaller and more locked-down hardware instead: an RTOS target, hardware security modules and per-device certificate identity. That is a move toward embedded, fleet-managed deployments rather than gateway servers.
◆ Prediction
Expect follow-up 0.25.x releases fixing Zephyr-specific issues, since 0.25.7 is labelled a first beta. The SipHash client ID question raised in 0.25.2 still has no resolution in these entries.
