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

In plain words

Tambo is an open-source React SDK that enables applications to render and control UI components through natural language input. It allows developers to register React components that an AI assistant can display or update based on user requests. The SDK supports context fetching via Model Context Protocol or client-side requests, handles streaming responses, maintains conversation history, and works with Next.js, Remix, Vite, and React Native. It's designed for developers building AI-powered interfaces who want to bring Cursor-like functionality to their own applications.

In the maker’s words, at launch

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…

  One – A new React framework unifying web, native and local-first2024 · onestack.dev · ▲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. ---…

  Onlook – Open-source, visual-first Cursor for designers2025 · github.com · ▲408

  Hey HN, I’m Kiet – one half of the two-person team building Onlook (https://beta.onlook.com/), an open-source [https://github.com/onlook-dev/onlook/] visual editor that lets you edit and create React apps live on an infinite canvas. We launched Onlook [1][2] as a local-first Electron app almost a year ago. Since then, “prompt-to-build” tools have blown up, but none let you design and iterate visually. We fixed that by taking a visual-first, AI-powered approach where you can prompt, style, and directly manipulate elements in your app like in a design…

  Kitten TTS – 25MB CPU-Only, Open-Source TTS Model▲1,003

  Kitten TTS is an open-source series of tiny and expressive text-to-speech models for on-device applications. We are excited to launch a preview of our smallest model, which is less than 25 MB. This model has 15M parameters. This release supports English text-to-speech applications in eight voices: four male and four female. The model is quantized to int8 + fp16, and it uses onnx for runtime. The model is designed to run literally anywhere eg. raspberry pi, low-end smartphones, wearables, browsers etc. No GPU required! We're releasing this to give early users a sense of the latency and voices…

  I was wondering how I can arrange objects along a spherical helix path, and read some articles on it. I ended up learning about parametric equations again, and make this visualization to document what I learned: https://visualrambling.space/moving-objects-in-3d/ feel free to visit and let me know what you think!

  The current sky at your approximate location, as a CSS gradient▲788

  For HTML Day 2025 [1], I made a web service that displays the current sky at your approximate location as a CSS gradient. Colours are simulated on-demand using atmospheric absorption and scattering coefficients. Updates every minute, without the use of client-side JavaScript. Source code and additional information is available on GitHub: https://github.com/dnlzro/horizon [1] https://html.energy/html-day/2025/index.html
