Convex vs Z-Wave JS
A side-by-side editorial comparison of Convex and Z-Wave JS — release velocity, themes, recent moves, and the top alternatives to consider.
Convex vs Z-Wave JS: at a glance
What is Convex?
Convex raised $57M on the argument that agents need a backend built for them.
The feed is thin on releases and heavy on company milestones. A $57M Series B led by Insight Partners is the newest item, pitched around developers and their agents writing software together and needing a backend that keeps up. The substantive product news remains April's Convex for Enterprise, which added the compliance and scale posture the platform previously lacked; since then the feed carries a conference announcement and open-source recaps rather than shipped capability.
What is Z-Wave JS?
Z-Wave JS v15.32.0 ships the findings of two full-codebase security reviews.
v15.32.0 is the result of two security and correctness reviews of the whole codebase. No major issues were found, but it hardens S2, ESPHome, Transport Service and config parsing, caps firmware file sizes, limits outstanding S0 nonces and makes every firmware update stage abortable. ESPHome encryption keys no longer need manual URL encoding, and the release adds seven device config changes.

Convex
2.5DEVOPS
Convex raised $57M on the argument that agents need a backend built for them.
◆ Current state
The feed is thin on releases and heavy on company milestones. A $57M Series B led by Insight Partners is the newest item, pitched around developers and their agents writing software together and needing a backend that keeps up. The substantive product news remains April's Convex for Enterprise, which added the compliance and scale posture the platform previously lacked; since then the feed carries a conference announcement and open-source recaps rather than shipped capability.
◆ Where it's heading
Convex is funding and positioning ahead of shipping. The enterprise release established the upmarket motion and the funding narrative attaches it to agent-written code, but nothing in the visible window shows the agent-facing product surface that framing implies. Whether that framing is real or aspirational is not something this feed answers yet.
◆ Prediction
With the round announced around agent workloads, the next substantive release is most likely on that surface, though the entries here give no detail on what form it takes.
Z-Wave JS
5.0DEVOPS
Z-Wave JS v15.32.0 ships the findings of two full-codebase security reviews.
◆ Current state
v15.32.0 is the result of two security and correctness reviews of the whole codebase. No major issues were found, but it hardens S2, ESPHome, Transport Service and config parsing, caps firmware file sizes, limits outstanding S0 nonces and makes every firmware update stage abortable. ESPHome encryption keys no longer need manual URL encoding, and the release adds seven device config changes.
◆ Where it's heading
After a run of endpoint-grouping and controller-migration releases, the project spent a cycle on defensive hardening rather than features. Device config work continues alongside, now including endpoint grouping for more shutters. The development MCP server getting path restrictions shows the review reached tooling too.
◆ Prediction
Expect a v15.32.x patch for regressions from the hardening, then a return to device config and endpoint grouping work.
