Scalingo vs Z-Wave JS
A side-by-side editorial comparison of Scalingo and Z-Wave JS — release velocity, themes, recent moves, and the top alternatives to consider.
Scalingo vs Z-Wave JS: at a glance
What is Scalingo?
Scalingo removes swap for new apps while keeping runtime dependencies current
Scalingo's recent changelog is dominated by buildpack dependency updates — Node.js 24.x and 26.x, Go 1.26/1.27, PHP 8.4/8.5, and Python ecosystem tools (uv, Poetry, Pipenv). The most operationally significant change is a platform policy effective 1 September 2026: newly created applications no longer use swap memory, and existing apps will have their swap capped at 25% of container memory after next restart.
What is Z-Wave JS?
Z-Wave JS overhauls its RCP firmware driver in a nine-PR push toward production readiness.
Z-Wave JS v15.x is in active maintenance and incremental feature development, shipping roughly every 1–3 weeks. The library is the backbone of Z-Wave support in Home Assistant via the Z-Wave JS add-on, and recent releases have split attention between hardware driver improvements (RCP support, proprietary controller commands) and protocol reliability (command deduplication, interview sequencing, S2 encapsulation fixes). The v15.28.0 RCP driver overhaul is the most concentrated single-version effort in this range.

Scalingo removes swap for new apps while keeping runtime dependencies current
◆ Current state
Scalingo's recent changelog is dominated by buildpack dependency updates — Node.js 24.x and 26.x, Go 1.26/1.27, PHP 8.4/8.5, and Python ecosystem tools (uv, Poetry, Pipenv). The most operationally significant change is a platform policy effective 1 September 2026: newly created applications no longer use swap memory, and existing apps will have their swap capped at 25% of container memory after next restart.
◆ Where it's heading
Scalingo is moving toward harder memory limits that require applications to be correctly sized rather than relying on swap as a buffer. The no-swap policy, combined with consistent runtime version currency, suggests the platform is prioritizing reliability and predictable performance over forgiveness. Existing apps face a real deadline at end-of-2026 when the swap cap takes effect after any restart.
◆ Prediction
Expect continued weekly runtime version bumps and likely documentation or tooling additions to help users adapt their applications to the no-swap policy before the end-of-2026 deadline.
Z-Wave JS
6.3DEVOPS
Z-Wave JS overhauls its RCP firmware driver in a nine-PR push toward production readiness.
◆ Current state
Z-Wave JS v15.x is in active maintenance and incremental feature development, shipping roughly every 1–3 weeks. The library is the backbone of Z-Wave support in Home Assistant via the Z-Wave JS add-on, and recent releases have split attention between hardware driver improvements (RCP support, proprietary controller commands) and protocol reliability (command deduplication, interview sequencing, S2 encapsulation fixes). The v15.28.0 RCP driver overhaul is the most concentrated single-version effort in this range.
◆ Where it's heading
The dominant hardware trend in Z-Wave JS is Radio Co-Processor (RCP) architecture support — the new topology used by Nabu Casa Yellow and similar embedded smart home hubs, where the radio is a co-processor with separately updatable firmware rather than a monolithic USB stick. The library is making a clear investment in this path. Alongside that, interview reliability improvements (pausing during inclusion, deduplication of queued commands) signal a focus on reducing setup friction for multi-device deployments.
◆ Prediction
RCP support will graduate from experimental to stable in a coming release as the driver matures. The `lastAwake` persistence added in v15.29.0 is the kind of foundational telemetry that enables smarter polling and sleep-cycle optimization — expect follow-on features that use it.
