Rivet

DEVOPS
Velocity6.3

Rivet is rebuilding its actor backend into managed infrastructure for AI agents.

◆Current state
Rivet ships an actor-model backend - durable per-actor state, SQLite, queues - and is now stacking AI-agent infrastructure on top of it: agentOS (WASM micro-VMs for running coding agents), Secure Exec (isolated process execution), and SDKs in Rust and Effect. The pace is unusual: five 'Introducing' releases in ten days. The core is being rewritten in Rust as it goes.
◆Where it's heading
The center of gravity is moving from a framework for stateful actors toward a managed platform for hosting agents and their compute. Rivet Compute adds one-command serverless hosting; agentOS and Secure Exec target the sandbox-for-coding-agents market directly. Each release widens the surface a developer can run without managing infrastructure.
◆Prediction
Expect Rivet to keep filling out the managed-hosting story around Compute - pricing, regions, and tighter agentOS/Secure Exec integration so the actor model and the agent sandbox share one deploy path.

◆Recent moves

  1. 2d ago

    Introducing agentOS v0.2

    The second iteration of agentOS folds agent orchestration into the WASM micro-VM, extending the sandbox-for-coding-agents bet introduced in April toward running and coordinating multiple agents.

  2. 8d ago

    Secure Exec v0.3

    A full Rust rewrite of Secure Exec adds process isolation and Bun support, hardening the execution layer that underpins running untrusted agent code.

  3. 10d ago

    Introducing Rivet Compute

    ⚡ SPARK

    A serverless hosting platform for actors, deployable in one command - the managed-infrastructure layer that turns Rivet's framework into a place to run production backends.

  4. 10d ago

    Introducing the Rust SDK for Rivet Actors

    A native, typed Rust SDK brings Rivet Actors to Rust developers, broadening the language surface beyond the existing clients.

  5. 11d ago

    Introducing the Effect SDK for Rivet Actors

    A first-class Effect SDK makes Rivet Actors stateful within Effect's Scope/Ref/Layer model, courting the TypeScript-Effect community.

  6. 12d ago

    Introducing Rivet 2.3

    Rivet 2.3 rewrites RivetKit in native Rust, reworks the dashboard, and adds fine-grained actor-lifecycle control - the core-platform groundwork the newer SDKs and Compute build on.
