Prometheus vs Z-Wave JS
A side-by-side editorial comparison of Prometheus and Z-Wave JS — release velocity, themes, recent moves, and the top alternatives to consider.
Prometheus vs Z-Wave JS: at a glance
What is Prometheus?
Prometheus 3.16 reaches rc.4 with an integral() function and stricter exemplar handling
Prometheus 3.16 is on its fourth release candidate, dated 3 November. Beyond rc.2's stable Smoothed and Anchored selectors and flag-gated query cost limits, rc.4 adds an experimental integral() PromQL function, per-query start-timestamp overrides via an HTTP header, and metadata-wal-records in Agent mode. It also tightens accounting: subquery samples now count toward query statistics, and exemplars with duplicate label names are rejected.
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.

Prometheus 3.16 reaches rc.4 with an integral() function and stricter exemplar handling
◆ Current state
Prometheus 3.16 is on its fourth release candidate, dated 3 November. Beyond rc.2's stable Smoothed and Anchored selectors and flag-gated query cost limits, rc.4 adds an experimental integral() PromQL function, per-query start-timestamp overrides via an HTTP header, and metadata-wal-records in Agent mode. It also tightens accounting: subquery samples now count toward query statistics, and exemplars with duplicate label names are rejected.
◆ Where it's heading
The 3.16 cycle is about making query cost measurable and controllable: accurate sample counts are a prerequisite for the cost limits rc.2 introduced. Remote Write 2.0 keeps shedding legacy metadata metrics, and the patch tracks (3.15.x, 3.13 LTS) keep moving separately on security rebuilds.
◆ Prediction
A 3.16.0 GA is the likely next entry, given four candidates in about a week; whether query-cost leaves its feature flag in that release is not yet visible.
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.
