Infrastructure for
software that thinks.
Actors are the primitive for AI agents — and the realtime apps and workflows around them. They burst when traffic spikes, sleep when idle, and run anywhere: Rivet Cloud, your VPC, or fully air-gapped.
The Thinker
Auguste Rodin · modeled 1880
Two products, one platform.
Rivet Actors give agents and realtime apps durable, stateful compute in your existing Node.js or Bun backend. agentOS gives agents a portable OS to run in. Use them alone or together.
Actors
The primitive for stateful workloads.
Co-located with compute for instant reads and writes.
Long-lived when active, hibernates when idle.
Sleeps at near-zero cost when idle, fans out when traffic spikes.
Deploy close to your users without complexity.
Real-time bidirectional streaming built in.
Multi-step operations, durable queues, and timers.
agentOS
A portable, lightweight in-process OS for agents. Open source, built on Wasm + V8.
Near-zero cold start with minimal overhead.
V8 isolates + Wasm instead of full VM sandboxes.
Your APIs. Your toolchains. No complex agent auth.
S3, SQLite, Google Drive, or the host file system.
V8 isolates + WebAssembly. Configurable policies.
Rivet Cloud, Railway, Vercel, Kubernetes, or on-prem.
Built-In Observability
Debugging and monitoring for actors and agents, from local development to production at scale.
SQLite Viewer
Browse and query SQLite databases in real-time across actors and agent sessions
Workflow State
Inspect workflow progress, steps, and retries as they execute
Event Monitoring
Track every state change, action, and agent event as it happens in real-time
REPL
Debug actors and agent sessions by calling actions, subscribing to events, and interacting directly with your code
Start local. Scale to millions.
A library in development, a platform in production. Your backend keeps deploying wherever it already does — Rivet connects to it.
Just a Library
Install a package and run locally. No servers, no infrastructure. Actors run in your process during development.
Rivet Cloud
Fully managed Actors and agentOS on a global edge network. Connects to your existing cloud — Vercel, Railway, AWS, wherever you deploy.
Sign UpSelf-Host
Single Rust binary or Docker container. Works with Postgres, file system, or FoundationDB (enterprise). Full dashboard included.
Run it where your data lives.
A single binary you control. Deploy Rivet inside your VPC, your customer’s VPC, or fully air-gapped, with the compliance you already have.
- Air-gapped and on-prem: no outbound calls, no telemetry leaving your boundary
- Embed in your customers’ VPCs: they keep their data, you keep your product
- FedRAMP, HIPAA, sovereign clouds: stay inside the boundary your controls already cover
Infrastructure for
the agentic era.
Build with agents, build for agents, and run it where your data lives.
