What is Echo?
Echo is running two lines in lockstep, and security is what triggers releases
Echo maintains v4 and v5 in parallel and treats security parity as non-negotiable — both of the vulnerabilities in this window were fixed on v5 and backported to v4 within hours. The issues themselves are the same class twice over: values taken from request headers and paths being trusted too readily. Context.Scheme accepted malformed forwarded scheme values, and encoded path separators in static file URLs could bypass route-level middleware and disclose files.
What is Rivet?
agentOS is becoming infrastructure other agent platforms build on, not a Rivet feature
Rivet has consolidated around agentOS, a virtual operating system that gives agents a terminal, filesystem and networking on WebAssembly and V8 isolates inside a backend you already run, instead of a container or VM per agent session. The surrounding pieces are now in place: a package registry, an install path measured in microseconds, durable timezone-aware cron for actors, and an execution API that runs JavaScript and Python directly rather than shelling out to bash. Underneath it, the team is building its own storage layer — a zero-disk SQLite engine that keeps writes local-fast while cold pages tier out to object storage.
Echo vs Rivet: editorial side-by-side
Echo

Echo is running two lines in lockstep, and security is what triggers releases
◆ Current state
Echo maintains v4 and v5 in parallel and treats security parity as non-negotiable — both of the vulnerabilities in this window were fixed on v5 and backported to v4 within hours. The issues themselves are the same class twice over: values taken from request headers and paths being trusted too readily. Context.Scheme accepted malformed forwarded scheme values, and encoded path separators in static file URLs could bypass route-level middleware and disclose files.
◆ Where it's heading
The pattern that matters is where each vulnerability lived: both sat in code that decides what a request is, before any application logic runs, which is where a web framework's security surface actually is. Feature work is confined to v5 — an optional rate-limiter store context for response headers, core hot-path optimisation — while v4 receives security fixes only, a clean maintenance split with no ambiguity about which line is current.
◆ Prediction
Expect v5 to keep taking the middleware and performance work while v4 continues receiving same-day security backports, and further hardening around path and header parsing given that two reported issues in a row landed there.
Rivet
7.5DEVOPS
agentOS is becoming infrastructure other agent platforms build on, not a Rivet feature
◆ Current state
Rivet has consolidated around agentOS, a virtual operating system that gives agents a terminal, filesystem and networking on WebAssembly and V8 isolates inside a backend you already run, instead of a container or VM per agent session. The surrounding pieces are now in place: a package registry, an install path measured in microseconds, durable timezone-aware cron for actors, and an execution API that runs JavaScript and Python directly rather than shelling out to bash. Underneath it, the team is building its own storage layer — a zero-disk SQLite engine that keeps writes local-fast while cold pages tier out to object storage.
◆ Where it's heading
The argument Rivet keeps making is an economic one: a sandbox holds a whole container open while the agent sits idle waiting on inference, which is the cost structure isolates already solved. That case is no longer only Rivet's to make — Vercel's Eve and Flue both shipped agentOS support within two days of each other, which moves agentOS from a product surface toward a layer other vendors depend on. The recent work has shifted accordingly, from proving the runtime to filling in what a runtime needs to be depended on: execution APIs, scheduling, and now durable storage.
◆ Prediction
With the execution API and storage engine landing back to back, the next gap in the stack is state and data access for agents built on agentOS — expect the SQLite tiering work to surface as a product surface actors can call, not just an engineering post. A third platform adoption announcement in the same changelog format is the other pattern the entries support.
