Hono vs Rivet
Side-by-side trajectory, velocity, and editorial themes.
Hono runs a tight security-and-fix cadence, hardening its middleware release by release.
Hono is in mature-framework maintenance mode: frequent point releases that pair small correctness fixes and build/CI housekeeping with a steady drip of security patches. The recent stretch has been dominated by security work — per-request context isolation in the JSX/SSR path, a CORS credentials-with-wildcard fix, and mount-prefix path-decoding — alongside routine middleware polish.
The direction is hardening rather than expansion: Hono is tightening the edge cases in its middleware (serve-static, compress, CORS, bearer-auth) and its multi-runtime story (Deno, Bun, Lambda edge) while shipping the occasional small API addition like a public Context export. The security-fix frequency suggests active bug-bounty or audit attention, and the team is prioritizing correctness of the request lifecycle over new surface area.
Expect the same rhythm — frequent patch releases weighted toward middleware fixes and security disclosures, with incremental feature flags rather than large new subsystems.
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.
