Hey HN, this is Nathan and Nicholas from Rivet (https://rivet.dev) – a fast, high-density, and scalable orchestrator for agentic workloads using the actor model. Rather than running a heavyweight sandbox per agent, each agent gets a lightweight actor backed by S3. Actors provide a long-lived process for long agent turns, in-memory state for context, a WebSocket server for multiplayer, durable SQLite storage backed by S3, and hibernation when idle. It's a similar model to Cloudflare Durable…

A few top-level comments from Hacker News, shortened. Read the full thread on Hacker News.
> When you write data to an actor’s SQLite database, the write is acknowledged once SSDs in 2 of 3 availability zones have it. Then, the data is batched to S3 in the background. This means that S3 is never on the write path, which lowers latency and cost. When reading data or waking an actor, Rivet reads from SSDs if…
Distributed actors are also good platforms to run graph algorithms. We're evaluating Rivet as a potential substrate to run page rank and clustering algorithms on large graphs, while supporting cypher queries over the result. https://github.com/orgs/Latentpedia/discussions/4 Related work:…
Fascinating architecture—treating agent turns as persistent lightweight actors backed by tiered SQLite/S3 rather than spinning up dedicated VMs makes a lot of sense for latency and cost. For workflows that inevitably require arbitrary shell execution or local compiler tools (like coding agents running tests), do you…
