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.
What is Speakeasy?
Speakeasy stopped inventorying MCP servers and started adjudicating them.
Speakeasy ships near-daily platform releases with unusually legible notes — each headline states what changed for a user, not a version number. The current one turns the Shadow MCP page into a single review surface where every server carries an approval state and an automatically gathered evidence dossier: publisher, requested scopes, declared capabilities, maintenance signals, and whether internal teams already talk to it. Decisions enforce on record. Around it, the assistant surfaces have been consolidating: one detail panel for configuration and observation, exact session totals, and canonical identities folding a person's work and personal AI accounts together.

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.
Speakeasy
10.0DEVOPS
Speakeasy stopped inventorying MCP servers and started adjudicating them.
◆ Current state
Speakeasy ships near-daily platform releases with unusually legible notes — each headline states what changed for a user, not a version number. The current one turns the Shadow MCP page into a single review surface where every server carries an approval state and an automatically gathered evidence dossier: publisher, requested scopes, declared capabilities, maintenance signals, and whether internal teams already talk to it. Decisions enforce on record. Around it, the assistant surfaces have been consolidating: one detail panel for configuration and observation, exact session totals, and canonical identities folding a person's work and personal AI accounts together.
◆ Where it's heading
The arc runs observe, then intercept, now adjudicate. Earlier releases catalogued spend and inventoried shadow MCP servers; the LiteLLM integration moved enforcement to the proxy so a violating prompt dies before inference; this release supplies the judgment layer, doing the research an approver would otherwise do by hand. The supporting work points the same way — prompt-injection scanning of captured skill manifests, risk policies that pause instead of being deleted, identity resolution that reports a whole person rather than an account. Each is a piece a control plane needs before its verdicts can be trusted.
◆ Prediction
Expect approval state to start gating traffic rather than only recording a decision, and the evidence dossier to extend from MCP servers to the skills and assistants already being captured. The rollout flag on the approval workflow suggests general availability is the next step rather than new capability.
