NATS vs Z-Wave JS UI
A side-by-side editorial comparison of NATS and Z-Wave JS UI — release velocity, themes, recent moves, and the top alternatives to consider.
NATS vs Z-Wave JS UI: at a glance
What is NATS?
NATS 2.15.2 closes auth-callout and leafnode ACL gaps on both supported lines.
NATS shipped 2.15.2 and 2.14.9 together on Oct 26, the first patches since 2.15.1 went final. Both carry the same fixes: auth callout now respects allowed connection types, leafnode ACLs no longer implicitly allow $MQTT.> permissions, OCSP responses are bound to the certificate serial, and restored v1 snapshots are bounds-checked. Both also move to Go builds that distrust eMudhra intermediates.
What is Z-Wave JS UI?
Z-Wave JS UI 11.25.2 fixes HTTPS certificates that the new Node 24 image rejected.
Z-Wave JS UI mostly tracks the zwave-js driver, but 11.25.0 was a fuller feature release with Configuration CC entity defaults, tighter column filters and min/max/step value hints. The Docker image moved to Node 24 in that release, and 11.25.2 now regenerates self-signed HTTPS certificates that Node 24 rejected. 11.25.1 bumped Node to 24.22.1 and zwave-js to 15.31.2.

NATS
5.0DEVOPS
NATS 2.15.2 closes auth-callout and leafnode ACL gaps on both supported lines.
◆ Current state
NATS shipped 2.15.2 and 2.14.9 together on Oct 26, the first patches since 2.15.1 went final. Both carry the same fixes: auth callout now respects allowed connection types, leafnode ACLs no longer implicitly allow $MQTT.> permissions, OCSP responses are bound to the certificate serial, and restored v1 snapshots are bounds-checked. Both also move to Go builds that distrust eMudhra intermediates.
◆ Where it's heading
After 2.15's desired-state metalayer, the release stream has turned to hardening: two rounds of metalayer data-safety fixes in 2.15.1, now a batch of authorization and certificate-validation fixes. Every 2.15 patch is mirrored to 2.14, so the project is carrying two lines in parallel while 2.15 adoption grows.
◆ Prediction
Expect paired 2.15.3 / 2.14.10 candidates within a few weeks, continuing the mirrored cadence. The entries don't show when 2.14 support ends.
Z-Wave JS UI
5.0DEVOPS
Z-Wave JS UI 11.25.2 fixes HTTPS certificates that the new Node 24 image rejected.
◆ Current state
Z-Wave JS UI mostly tracks the zwave-js driver, but 11.25.0 was a fuller feature release with Configuration CC entity defaults, tighter column filters and min/max/step value hints. The Docker image moved to Node 24 in that release, and 11.25.2 now regenerates self-signed HTTPS certificates that Node 24 rejected. 11.25.1 bumped Node to 24.22.1 and zwave-js to 15.31.2.
◆ Where it's heading
Releases alternate between thin driver bumps and occasional UI and Home Assistant discovery batches. The Node 24 move is producing its own follow-up fixes, and the Home Assistant integration remains where most user-facing changes land.
◆ Prediction
Expect the next releases to go back to zwave-js and Node patch bumps, possibly with more Node 24 compatibility fixes, and another UI batch in a few weeks.
