Rivet Actors – Durable Objects built with Rust, FoundationDB, Isolates
Hello! We posted a Show HN for Rivet last year for our container orchestration project (https://news.ycombinator.com/item?id=37188659). In that time, a lot has changed that I think HN will find interesting. Rivet is open-source actor infrastructure similar to Cloudflare's Durable Objects. Rivet itself already serves millions of MAU in production using our current container runtime – primarily for multiplayer games – and Rivet Actors are a new extension to support actor-like workloads. Rivet Actor's core primitives are RPC, state, and events. Actors are powered by Rust, V8…
Rivet Actors – Durable Objects built with Rust, FoundationDB, Isolates launched on December 20, 2024 with 133 votes, #323 of 5,365 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
Rivet Actors is an open-source actor infrastructure platform for building distributed workloads, similar to Cloudflare's Durable Objects. Built with Rust, V8 isolates, and FoundationDB, it provides RPC, state management, and event primitives for developers. The platform already powers millions of monthly active users in production, primarily serving multiplayer games. Rivet Actors supports Deno and is designed for applications requiring scalable, stateful actor-based computation.

Rivet – Open-source game server management with Nomad and Rust2023 · github.com · ▲327Hey HN! Rivet is an OSS game server management tool that enables game developers to easily deploy their dedicated servers without any infra experience. We recently open-sourced Rivet after working on it for the past couple of years. I wanted to share some of my favorite things about our experience building this with the HN community. My cofounder and I have been building multiplayer games together since middle school for fun (and not much profit [1]). In HS, I stumbled into building the entire infrastructure powering [Krunker.io](http://Krunker.io) (acq by FRVR) & other popular…
Rivet – open-source AI Agent dev env with real-world applications2023 · rivet.ironcladapp.com · ▲176We just launched Rivet, the open-source visual AI programming environment! We built Rivet, because we were building complex AI Agent applications at Ironclad. It unlocked our abilities here, and we're excited to make available to the entire community. Backstory: A few months ago, inspired by things like LangChain and LlamaIndex, we started building an AI agent that could work with legal contracts. Unfortunately, we couldn't just use retrieval augmented generation (RAG), because a lot of contracts are basically identical (many chunks with near-identical embeddings), except for a few key…
SQLite for Rivet Actors – one database per agent, tenant, or documentFeb 2026 · github.com · ▲45Hey HN! We posted Rivet Actors here previously [1] as an open-source alternative to Cloudflare Durable Objects. Today we've released SQLite storage for actors (Apache 2.0). Every actor gets its own SQLite database. This means you can have millions of independent databases: one for each agent, tenant, user, or document. Useful for: - AI agents: per-agent DB for message history, state, embeddings - Multi-tenant SaaS: real per-tenant isolation, no RLS hacks - Collaborative documents: each document gets its own database with built-in multiplayer - Per-user databases: isolated, scales…

Ractor – a Rust-based actor framework with clusters and supervisors2023 · github.com · ▲168SOME HIGHLIGHTS. * We have a full supervision tree so actors can monitor other actors for exits and unhandled panic!s (at least the ones that can be caught) * The actor lifecycle is handled for you in a simple single-threaded, message handler primitive * You have a mutable state with each message handling call, so you have an easy way to create stateful actors and update that state as messages are processed * Actors talk to other actors by message passing, but there are remote-procedure-calls (RPCs) so actors can "ask a question" to another actor and wait on the reply. * A lot of the…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
