Rivet 3.0 Preview runs as one stateless binary on WarpDrive, with S3 as its only dependency.

◆Current state
Rivet has spent two months building infrastructure for long-lived actors and AI agents: BYOC in customer clouds, OpenTelemetry tracing, actor-scoped JWTs, Pi agent runtimes and agentOS Hosted VMs. On October 5 it said 3.0 would replace NATS with S3. The October 26 3.0 Preview delivers that: a new storage engine, WarpDrive, promises bottomless storage on S3 at SSD speed, and Rivet becomes a single stateless binary.
◆Where it's heading
Each release removes operational burden: BYOC moved the control plane into the customer's cloud, and 3.0 reduces the self-hosted footprint to one binary plus an S3 bucket. The agent work (Pi, agentOS) sits on top as the main workload Rivet is courting.
◆Prediction
Expect benchmarks and migration guidance for 2.x users during the preview, followed by a 3.0 GA. The entry gives no performance numbers, so the SSD-speed claim is unverified.

    Introducing Rivet 3.0 Preview

    ⚡ SPARK

    The October 5 plan to drop NATS for S3 is now a usable preview, built on a new storage engine called WarpDrive. It caps a run of releases aimed at making Rivet cheaper to operate wherever it runs.

    Introducing agentOS 0.4 & Hosted VMs

    agentOS 0.4 lets developers create durable Hosted VMs by ID and drive them from RivetKit or plain HTTP, with scoped JWTs for direct client access. It fills in the sandbox half of the harness-in-backend, tools-in-sandbox split that Pi 1.0 and Pi Durable rely on.

    Introducing Pi Durable for Rivet

    Pi Durable runs inside a Rivet Actor and checkpoints every model request and tool call to SQLite, so runs finish through crashes and deploys. A week after Pi 1.0 hosting, it adds durability, the property that makes multi-hour agent runs practical on Rivet.

    Replacing Our Message Broker with... S3?

    ⚡ SPARK

    Rivet 3.0 replaces NATS with S3, leaving object storage as its only infrastructure dependency. It completes the S3-tiered storage arc that began with July's zero-disk SQLite engine, and it makes the BYOC and self-host stories much lighter to run.

    Introducing Pi 1.0 for Rivet

    Pi 1.0 runs on Rivet Actors at 0.82 MB of RAM per session, with the harness in the customer's backend and tools in a separate sandbox. It is a concrete demonstration of the harness-outside-the-sandbox pattern Rivet has been advocating since July.

    Introducing JWT Authentication for Rivet Actors

    Short-lived, actor-scoped JWTs let clients connect to actors directly, with Auth0, Clerk, Better Auth, or custom sessions as the issuer. It removes the need for a proxy layer and is one of the enterprise controls stacked on top of BYOC.
