Reagent – graph based framework for building AI agent with UI
Hey HN! I'm excited to share Reagent, an open source Javascript framework to build UI rich AI agents using graph based workflow. Github: https://github.com/reagentai/reagent There are already amazing tools for building agents but most of them seem to be focused on building the AI workflow on the backend with markdown as final output. There is generative UI in AI SDK from vercel but it seems to work only with server components afaik. So, I created a framework for building AI agents with interactive UI components; you can render any component from LLM tool, update it's…
Reagent – graph based framework for building AI agent with UI launched on June 6, 2024 with 10 votes, #1,097 of 4,672 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 2 years on.
In plain words
Reagent is an open-source JavaScript framework for building AI agents with interactive user interfaces using graph-based workflows. Instead of backend-only processing with markdown output, it lets developers render UI components directly from language model tools, update their state, and visualize the agent workflow as an automatically generated graph. It is designed for developers building AI agents in JavaScript who need rich, interactive interfaces alongside agent logic.

PageAgent, A GUI agent that lives inside your web appMar 2026 · alibaba.github.io · ▲147Title: Show HN: PageAgent, A GUI agent that lives inside your web app Hi HN, I'm building PageAgent, an open-source (MIT) library that embeds an AI agent directly into your frontend. I built this because I believe there's a massive design space for deploying general agents natively inside the web apps we already use, rather than treating the web merely as a dumb target for isolated bots. Currently, most AI agents operate from external clients or server-side programs, effectively leaving web development out of the AI ecosystem. I'm experimenting with an "inside-out" paradigm instead. By…

VoltAgent2025 · github.com · ▲162Hi HN, I'm founder of VoltAgent, a new open-source TypeScript-based framework for building AI agents. We know there are many frameworks out there. Our short story of why we built VoltAgent goes like this: We were developing an AI application ourselves. Initially, we tried existing frameworks. We also explored different flows using no-code tools. We noticed something interesting: the visual approach of tools like n8n made AI workflows much clearer and easier to understand. Building flows visually was neat and provided great visibility. However, we quickly ran into problems with no-code tools:…
