   Tambo Add A Cursor style assistant for React apps (OSS, self-hosted)▲11

   Hi HN-- Tambo is a React SDK that lets your app render and control UI components based on natural language input. We are hooked on Cursor and want all our apps (Stripe, Vercel, GitHub) to have the same experience. I should be able to type `update env key` and get a UI to add it. Tambo lets an AI assistant render or update the state of registered React components. It can fetch context via MCP (Model Context Protocol) or client-side fetches (similar to OpenAI tool calls). The SDK handles streaming messages and prop updates, maintains thread history, and passes context across turns. It’s BYOM…

   One – A new React framework unifying web, native and local-first▲506

   Hey HN, I'm Nate, the creator of Tamagui. One is a React framework that does two things differently in hopes of simplifying how we build websites and apps: 1. It unifies React Native and React web with typed file system routing by making Vite able to serve RN. This lets you share (or diverge) your code in a simpler way for cross-platform apps. 2. We've partnered with Zero (https://zerosync.dev) to make local-first work well. We've been building a solution in One that makes Zero supporting server rendering, without waterfalls, and with seamless server/client handoff. ---…

   Performative-UI – A react component library of design tropes▲1,181

   Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!

    Mastra 1.0▲451

    Hi HN, we’re Sam, Shane, and Abhi, and we’re building Mastra (https://mastra.ai), an open-source JavaScript SDK for building agents on top of Vercel’s AI SDK. You can start a Mastra project with `npm create mastra` and create workflow graphs that can suspend/resume, build a RAG pipeline and write evals, give agents memory, create multi-agent workflows, and view it all in a local playground. Previously, we built Gatsby, the open-source React web framework. Later, we worked on an AI-powered CRM but it felt like we were having to roll all the AI bits (agentic workflows, evals,…

    A Visual IDE for React▲479

    I made this because building UIs in a lexical medium like code is super annoying. I have to pre-render what I’m making in my head, and then jump between the browser and IDE to test. I was inspired by the developer console in chrome and safari since I end up editing css there because it’s ironically more convenient. Hope it’s useful!
