VerneMQ vs Rocket.Chat: at a glance
What is VerneMQ?
A slow, careful MQTT broker that spent two years landing one breaking storage change.
VerneMQ is in low-cadence maintenance on the 2.1.x line, with releases spaced months apart and a 2.1.3 release candidate open since April. The work is concentrated in the clustering metadata store (vmq_swc), the MQTT session state machine, and WebSocket listener behaviour — the parts operators actually file bugs against. Commercial binaries remain EULA-gated, so the open-source repo is the product surface and the packages are the business.
What is Rocket.Chat?
Rocket.Chat bundled semantic AI search, FIPS mode and air-gapped licensing into one regulated-buyer release.
Rocket.Chat publishes every release candidate as its own tagged entry, so the feed reads as a long run of dependency bumps punctuated by one substantial .rc.0 that carries the whole minor. The 8.7 line is that pattern at its clearest: four patch candidates moving nothing but a Meteor version and an audio seek fix, sitting on top of an rc.0 that added AI Search, FIPS-compliant cryptography, a server-side OAuth flow and an offline license flag. The cadence looks high and the substance is concentrated in a single tag.

VerneMQ
0.0COMMS
A slow, careful MQTT broker that spent two years landing one breaking storage change.
◆ Current state
VerneMQ is in low-cadence maintenance on the 2.1.x line, with releases spaced months apart and a 2.1.3 release candidate open since April. The work is concentrated in the clustering metadata store (vmq_swc), the MQTT session state machine, and WebSocket listener behaviour — the parts operators actually file bugs against. Commercial binaries remain EULA-gated, so the open-source repo is the product surface and the packages are the business.
◆ Where it's heading
The centre of gravity is correctness in clustered deployments, not new protocol capability. Recent releases keep tightening the same three areas — connection accounting under churn, proxy-header handling behind load balancers, and metadata sync for joining nodes — which reads as a broker being hardened for larger clusters rather than broadened. The RC-heavy release pattern (three RCs before 2.1.0, one open for 2.1.3) suggests a small team leaning on community testing before committing.
◆ Prediction
2.1.3 ships as a fix-consolidation release absorbing the remaining open PRs, with the retain-expiry default change carried through. Nothing in these entries points to a new protocol or storage direction after that.
Rocket.Chat
6.3COMMS
Rocket.Chat bundled semantic AI search, FIPS mode and air-gapped licensing into one regulated-buyer release.
◆ Current state
Rocket.Chat publishes every release candidate as its own tagged entry, so the feed reads as a long run of dependency bumps punctuated by one substantial .rc.0 that carries the whole minor. The 8.7 line is that pattern at its clearest: four patch candidates moving nothing but a Meteor version and an audio seek fix, sitting on top of an rc.0 that added AI Search, FIPS-compliant cryptography, a server-side OAuth flow and an offline license flag. The cadence looks high and the substance is concentrated in a single tag.
◆ Where it's heading
The 8.7 payload points squarely at buyers who cannot use a normal SaaS chat product — FIPS mode with dedicated Docker images across every microservice, an offline license flag that suppresses all outbound calls to Rocket.Chat Cloud and the Push Gateway, and a licenses.validate endpoint for previewing a license before applying it. AI Search arrives with OpenAI-compatible answers and an AI Center for configuration, which keeps the model choice in the operator's hands rather than the vendor's. Both arcs serve the same customer: the self-hosted, regulated deployment that wants semantic search without sending messages anywhere.
◆ Prediction
AI Center is described as configuration, which suggests more AI surfaces are meant to hang off it than search alone — summarisation or thread catch-up are the obvious candidates. The FIPS and offline flags are gated on new license modules, so expect the enterprise tier to keep absorbing the compliance work.
