Sanity vs Z-Wave JS
A side-by-side editorial comparison of Sanity and Z-Wave JS — release velocity, themes, recent moves, and the top alternatives to consider.
Sanity vs Z-Wave JS: at a glance
What is Sanity?
Sanity is building the headless CMS as an AI agent interface — a new MCP release nearly every day.
Sanity is in a sustained MCP server development sprint, shipping multiple versions per week. The MCP server now covers document creation, querying, publishing, asset management, content releases, and — as of v2.35.0 — workflow authoring and deployment by AI agents. The Studio itself is receiving stability work in parallel: Portable Text crash fixes, auth API modernization, and release management improvements. The pace of MCP iterations is more characteristic of an API startup in beta than an established CMS vendor.
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.

Sanity
7.5DEVOPS
Sanity is building the headless CMS as an AI agent interface — a new MCP release nearly every day.
◆ Current state
Sanity is in a sustained MCP server development sprint, shipping multiple versions per week. The MCP server now covers document creation, querying, publishing, asset management, content releases, and — as of v2.35.0 — workflow authoring and deployment by AI agents. The Studio itself is receiving stability work in parallel: Portable Text crash fixes, auth API modernization, and release management improvements. The pace of MCP iterations is more characteristic of an API startup in beta than an established CMS vendor.
◆ Where it's heading
Sanity is repositioning the MCP server as the primary integration layer for AI-driven content operations. Each release expands what an AI agent can do without a human at the Studio — from querying to publishing to now designing and deploying workflows. The guidance improvements in v2.35.1 and v2.35.2 show they're actively testing with LLM agents and fixing the failure modes that emerge. The trajectory is toward Sanity being the CMS you can fully operate through an agent.
◆ Prediction
The MCP server will extend to cover permissions and team membership management, and Sanity will likely offer a hosted agent runtime — essentially a place to run content pipelines that execute MCP tool calls on a schedule or trigger. Studio may shift to a configuration and monitoring layer for teams operating primarily through agents.
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.
