Jenkins vs Rivet
Side-by-side trajectory, velocity, and editorial themes.
Jenkins keeps its weekly cadence with UI refinement, security hardening, and steady bug fixes.
Jenkins continues its predictable weekly-release rhythm, with each version bundling small RFEs and a longer tail of bug fixes. The current focus areas are the experimental 'Manage Jenkins' UI overhaul, deserialization-safety hardening, and OS end-of-life messaging, alongside routine regression repairs from recent releases.
This is mature-project maintenance: incremental UI modernization, security tightening around serialization and CLI key types, and continued internationalization. No directional shifts—Jenkins is refining an established core rather than adding new capability surfaces.
Expect the weekly releases to keep pushing the experimental UI toward default status and continue security-hardening deserialization paths, with each version dominated by regression fixes rather than headline features.
Rivet pivots from actor backend to a coding-agent OS, and is building the ecosystem to match.
Rivet began as an actor and serverless backend platform — RivetKit, Rivet Actors, Rivet Compute — and has spent the last month reorienting around agentOS, a WebAssembly-based Linux environment for running coding agents without a heavy sandbox. The June and July releases show both threads running in parallel: native language SDKs (Rust, Effect) for Actors, and a fast-maturing agentOS that now has its own package registry.
The center of gravity is shifting from hosting stateful actors to being the runtime coding agents execute inside. agentOS went from a v0.2 sandbox alternative to shipping a package registry and a sub-millisecond package manager in under two weeks, a sign Rivet wants to own the developer surface around agent execution, not just the compute underneath it.
Expect agentOS to keep accreting ecosystem pieces — more registry content and tighter orchestration — while the Actors SDKs settle toward maintenance. A likely next move is deeper coupling between agentOS and Rivet Compute so agents run on Rivet's own cloud.
