Respond.io
Respond.io is tuning its AI agents for how messaging actually behaves, not how APIs do.
A side-by-side editorial comparison of VerneMQ and Drift — release velocity, themes, recent moves, and the top alternatives to consider.
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.
Drift now ships inside Salesloft's monthly train, and that train is being pointed at ChatGPT.
Product news for Drift arrives through Salesloft's monthly release notes following the merger, and increasingly through Clari's too. The August notes put the Salesloft MCP server inside ChatGPT as a custom connector while trimming transcript retrieval out of the Claude connector. July was governance work — tiered call-recording visibility and a separate download permission. June added AI adoption metrics to Analytics and Cadence Collections for managing cadence settings in bulk.

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.
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.

Two threads run through the last six months: agentic access to live Salesloft data, gated behind the Agentic add-on, and the permission scaffolding needed to sell that access to security teams. The MCP server launched in April, gained a second client surface in August, and simultaneously lost a tool — the surface is expanding while its scope is being pruned.
Expect the Agentic add-on to keep absorbing the AI feature line, and the transcript-access removal to be followed by explicit per-tool permissions rather than a blanket restore.
