Open-source orchestrator for agentic workloads built on Rivet Actors: long-lived processes with in-memory state, a per-Actor SQLite database on S3, WebSockets and scheduling, so every agent, user, session or tenant gets its own durable process that hibernates when idle.

Self-host on Docker, Kubernetes or a VM, or use Rivet Cloud or BYOC
Open Source
Open-source (Apache-2.0) and free to run locally or self-host, with S3 as the only dependency. Rivet Cloud (fully managed dedicated clusters on AWS or GCP) and BYOC (control plane in your own VPC, managed by Rivet) are managed options; see rivet.dev for their pricing.
Best for
Teams building production AI agents or multiplayer agent apps that need durable per-agent state, realtime connections and cheap idle capacity without running a VM per agent.
Not ideal for
Developers looking for a ready-made coding assistant, or teams whose agents need a full Linux VM for every session regardless of workload.
A well-engineered, actively shipped runtime that moves the agent loop out of the sandbox; strongest for TypeScript teams building agent products, less relevant if you only consume coding agents.
v3.0.6 was released on Nov 6, 2026, a day after v3.0.5; Rivet launched on Hacker News as a Launch HN (YC W23) on Nov 5, 2026, pitching agent orchestration on S3.
