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 runs a steady runtime-version maintenance cadence with a notable platform swap memory policy change.
Scalingo is a European PaaS (Heroku alternative) that keeps its buildpack ecosystem current across Ruby, Node.js, Go, Java, Python, and PHP. The release cadence is almost entirely version bumps: new runtimes and tooling versions land within days of upstream releases. The one platform-level change visible across recent entries is a swap memory policy shift—new applications no longer get swap memory as of September 2026, and existing apps will have swap reduced to 25% of container memory on their next restart. That's a behavioral change that affects memory-intensive applications.
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
5.0DEVOPS
Scalingo runs a steady runtime-version maintenance cadence with a notable platform swap memory policy change.
◆ Current state
Scalingo is a European PaaS (Heroku alternative) that keeps its buildpack ecosystem current across Ruby, Node.js, Go, Java, Python, and PHP. The release cadence is almost entirely version bumps: new runtimes and tooling versions land within days of upstream releases. The one platform-level change visible across recent entries is a swap memory policy shift—new applications no longer get swap memory as of September 2026, and existing apps will have swap reduced to 25% of container memory on their next restart. That's a behavioral change that affects memory-intensive applications.
◆ Where it's heading
Scalingo is in operational steady-state: a PaaS maintaining its runtime catalog and platform stability rather than expanding its product surface. No new features or architectural moves are visible in recent entries. The swap memory change suggests resource efficiency work at the infrastructure level, likely tied to capacity management or performance improvements on shared infrastructure. The support for multiple Python package managers (uv, Poetry, Pipenv) in parallel suggests responsiveness to the Python ecosystem's tooling fragmentation.
◆ Prediction
Scalingo will continue rapid runtime version tracking as upstream releases land. Any platform-level changes will be telegraphed by operational announcements like the swap memory notice. A directional move—new regions, GPU support, serverless containers—would need to appear in a product announcement rather than a buildpack entry.
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.
