Rivet – open-source AI Agent dev env with real-world applications
We 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…
Rivet – open-source AI Agent dev env with real-world applications launched on September 8, 2023 with 176 votes, #256 of 4,228 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 3 years on.
In plain words
Rivet is an open-source visual programming environment for building AI agents. Developed at Ironclad for creating complex agent applications, it provides a graphical interface for designing and debugging AI workflows. The tool addresses challenges in building sophisticated AI systems, such as those involving contract analysis, by offering visual debugging and chain-of-thought capabilities. It is designed for developers building production AI agent applications.

An open-source AI programming environment using a visual, node-based graph editor
Rivet is a visual programming environment for building AI agents with LLMs. Iterate on your prompt graphs in Rivet, then run them directly in your application. With Rivet, teams can effectively design, debug, and collaborate on complex LLM prompt graphs, and deploy them in their own environment. At Ironclad, we struggled to build AI agents programmatically. Rivet's visual environment, easy debugger, and remote executor unlocked our team's ability to collaborate on increasingly complex and powerful LLM prompt graphs. is the leading digital contracting platform. Ironclad AI helps legal teams with everything from reviewing contracts faster to answering questions about their obligations. Learn…from rivet.ironcladapp.com

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 Actors – Durable Objects built with Rust, FoundationDB, Isolates2024 · github.com · ▲133Hello! 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…

Hi HN! We just launched Verdent, an AI coding agent that actually plans before it codes, tests its own work, and delivers production-ready results without you having to clean up after it. tl;dr Check out the website [1] and read the story [2] - The problem: Current AI tools dump code and leave you to debug. You ask for "build a login endpoint" and get a passwordless JWT mess that doesn't fit your project. We've talked to hundreds of engineers who are frustrated with having to micromanage AI output. - What we built: Verdent works more like a senior engineer. It asks clarifying questions…
