What is Rivet?
Rivet Actors can now fork in 20 ms, SQLite database included, without copying data.
Rivet builds infrastructure for long-lived actors and AI agents: BYOC, OpenTelemetry tracing, actor-scoped JWTs and agentOS Hosted VMs. The 3.0 Preview made Rivet a single stateless binary on S3, and the Rust SDK reached general availability on 6 November. On 11 November Rivet added actor forking: a fork starts in 20 ms with the original actor's state and SQLite database and costs nothing until it writes.
What is Z-Wave JS?
Z-Wave JS patches the fallout from its security release and limits OTA updates to one node.
v15.32.0 shipped fixes from two full-codebase security reviews; the patches since then handle the fallout. v15.32.2 warns instead of failing at startup when Classic and Long Range security keys are shared, applies modified Central Scene labels on startup and adds labels for 61 devices. v15.32.3 limits OTA firmware transfers to one node at a time.
Rivet vs Z-Wave JS: editorial side-by-side
Rivet
7.5DEVOPS
Rivet Actors can now fork in 20 ms, SQLite database included, without copying data.
◆ Current state
Rivet builds infrastructure for long-lived actors and AI agents: BYOC, OpenTelemetry tracing, actor-scoped JWTs and agentOS Hosted VMs. The 3.0 Preview made Rivet a single stateless binary on S3, and the Rust SDK reached general availability on 6 November. On 11 November Rivet added actor forking: a fork starts in 20 ms with the original actor's state and SQLite database and costs nothing until it writes.
◆ Where it's heading
Rivet keeps turning its S3-backed storage engine into features for agent workloads. Copy-on-write forking follows from the 3.0 storage design and gives agents a cheap way to branch a session, try something and discard it. The SDK and auth work of the past two months points to Rivet positioning actors as the runtime for agent backends.
◆ Prediction
Forking is likely to show up next in agentOS and the Pi integrations as a way to branch agent runs; the entries do not say when 3.0 leaves preview.
Z-Wave JS
5.0DEVOPS
Z-Wave JS patches the fallout from its security release and limits OTA updates to one node.
◆ Current state
v15.32.0 shipped fixes from two full-codebase security reviews; the patches since then handle the fallout. v15.32.2 warns instead of failing at startup when Classic and Long Range security keys are shared, applies modified Central Scene labels on startup and adds labels for 61 devices. v15.32.3 limits OTA firmware transfers to one node at a time.
◆ Where it's heading
The project is in a stabilization phase after the hardening release, choosing warnings over hard failures where stricter checks broke real setups. Device config additions keep arriving in every patch.
◆ Prediction
Expect more small patches on the 15.32 line and continued device config additions before the next minor release.
