Onlook – Open-source, visual-first Cursor for designers

In plain words

Onlook is an open-source visual editor for building and editing React applications on an infinite canvas. Designed for designers and developers, it offers AI-powered features that let users prompt, style, and directly manipulate UI elements visually without leaving the editor. The browser-based tool combines visual-first design iteration with code generation, allowing real-time editing and creation of React apps in a design-tool-like interface.

In the maker’s words, at launch

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…

  Hi HN, I’m Kiet, one of the creators of Onlook studio. I made this app that allows you to visually edit your locally running React app and write the code back to it in real-time. The purpose is to allow you to develop UI while fully owning your code the whole time. There are other visual builders out there but they either require you to upload your code to the cloud or some lengthy setup process. Onlook runs locally, deterministically, and only requires adding a plugin for the compile step (2 lines of config change). Technical details: This is technically a web browser that can point to your…

  Once UI 1.5Dec 2025 · once-ui.com · ▲302

  When I started my career and built my first design system, I was beyond excited. It took a lot of iterations, learning and 6 months of work to launch it internally. In the next job, I did it again, then at the following job, again… And no matter which company I worked for, 80% of the design system was the same. I’ve decided to work full-time on the design system I’ve always wanted, and today I’m launching and open-sourcing it. You can use it to build Next.js apps faster, and I’ve designed it in a way that it’s hard to go wrong with it: you can choose any settings, and you’ll end up with a…

  A Visual IDE for React2022 · dev.aspect.app · ▲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!

  Tapflow 2.0▲1,125

  We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…
