Infrastructure for
the agentic era.

Actors are the primitive for AI agents, real-time apps,
and durable workflows. They burst when traffic spikes,
sleep when idle, run for hours, and hold state across regions.

Actors

The primitive for stateful workloads.

In-memory state

Co-located with compute for instant reads and writes.

Runs indefinitely, sleeps when idle

Long-lived when active, hibernates when idle.

Scales infinitely, scales to zero

Supports bursty workloads and is cost-efficient.

Global edge network

Deploy close to your users without complexity.

WebSockets

Real-time bidirectional streaming built in.

Workflows, Queues, Scheduling

Multi-step operations, durable queues, and timers.

agentOS

agentOS

A lightweight open-source operating system for any type of agent. Built on WASM & V8.

~6ms coldstart, 22 MB RAM

Near-zero cold start with minimal overhead.

32x cheaper than sandboxes

V8 isolates + WASM instead of full VMs.

Embed in your backend

Your APIs. Your toolchains. No complex agent auth.

Mount anything as a file system

S3, SQLite, Google Drive, or the host file system.

Granular security

V8 isolates + WebAssembly. Configurable policies.

Your laptop, your infra, or on-prem

Rivet Cloud, Railway, Vercel, Kubernetes, or on-prem.

Rivet Inspector Dashboard

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

Runs where you do.

Serverless, containers, or your own servers — Rivet Actors work with your existing infrastructure, frameworks, and tools.

Start local. Scale to millions.

RivetKit is a library. Connect it to Rivet Cloud or self-host when you need scaling, fault tolerance, and observability.

Just a Library

Install a package and run locally. No servers, no infrastructure. Actors run in your process during development.

$npm install rivetkit

Self-Host

Single Rust binary or Docker container. Works with Postgres, file system, or FoundationDB (enterprise). Full dashboard included.

$docker run -p 6420:6420 rivetdev/engine
Rivet

Rivet Cloud

Fully managed Actors and agentOS. Global edge network. Connects to your existing cloud — Vercel, Railway, AWS, wherever you already deploy.

  • Global Edge Network
  • Scales Seamlessly
  • Connects To Your Cloud

Run it where your data lives.

A single binary you control. Deploy Rivet inside your VPC, your customer’s VPC, or fully air-gapped. Use the compliance you already have instead of waiting on someone else’s.

Air-gapped and on-prem

Run the same Rivet that powers our cloud entirely inside your perimeter. No outbound calls, no telemetry leaving your boundary.

Embed in your customers

Ship Rivet inside your customer’s VPC, regulated environment, or on-prem hardware. They keep their data, you keep your product.

Your compliance posture, intact

FedRAMP, HIPAA, regulated industries, sovereign clouds. Deploying inside the boundary your existing controls already cover keeps the audit story simple.

Build with agents, build for agents, and run it where your data lives.
