24 alternatives to I Built DevTools for Blazor (Like React DevTools but for .NET)
Hi HN! I've been working on developer tools for Blazor that let you inspect Razor components in the browser, similar to React DevTools or Vue DevTools. The problem: Blazor is Microsoft's frontend framework that lets you write web UIs in C#. It's growing fast but lacks the debugging tools other frameworks have. When your component tree gets complex, you're stuck with Console.WriteLine debugging. What I built: A browser extension + NuGet package that: Shows the Razor component tree in your browser Maps DOM elements back to their source components Highlights components on hover Works with both…

21st.dev▲1,211I originally built this app to organize and reuse interesting React + Tailwind components I came across on Twitter, inspired by the shadcn/ui approach. Later, a friend started contributing their own components, and it got me thinking—this could grow into something bigger, like an NPM for design engineers to share and use components. Would love to hear your thoughts!

This is a project I've been working on since the start of Covid-19. I built an app so that I don't have to put data into online tools like JWT debugger, JSON formatter, URL decoder, etc... https://devutils.app The app works entirely offline and is open-source. I'm selling the pre-built version of the app to earn some revenue for my time. If you want to try the app but can't afford the price or don't have XCode to build the app, drop me an email (my profile), I'll be happy to provide you a free build. I would love to hear all the feedback/suggestions. Thanks!

Hi HN! Korean high school senior here, about to start CS in college. I built a browser engine from scratch in C++ to understand how browsers work. First time using C++, 8 weeks of development, lots of debugging—but it works! Features: - HTML parsing with error correction - CSS cascade and inheritance - Block/inline layout engine - Async image loading + caching - Link navigation + history Hardest parts: - String parsing(html, css) - Rendering - Image Caching & Layout Reflowing What I learned (beyond code): - Systematic debugging is crucial - Ship with known bugs rather than chase…

Hi folks, I've been working on a visual devtool chrome extension for Tailwind CSS for quite some time now and just launched in recently. It let's you tweak your website from the browser itself and copy the classes or html afterwards to paste in your IDE. It's especially well suited to try out changes quickly, but I've built most of the landing page with the help of the extension itself. You can try it out in the landing page itself (no need to install anything). Features: - Click on any class (eg: px-4) and try out other values easily. - Preview the website in responsive mode and quickly…

Hi all! Here is my open-source side-project. It is a browser extension that lets you click on a component on your localhost to get to its code in your editor. It works with React, Svelte, SolidJS, Preact, and Vue components and with VSCode, Webstorm, or any other editor that supports URL protocol links. It can be used also as JavaScript library (instead of installing browser extension) It speeds up my web development so much that I can't work without that anymore :D Let me know if you like it or if you would like to improve it somehow. Contributions are welcomed…

Hello everyone, For the past several months, I have been building multiple React/TailwindCSS components for my projects. I have decided to bundle and document them so that I can share them with the community. The entire UI kit is written in Typescript on top of the class-variance-authority library. Although I am already using these components in production, the project is still in beta since it lacks a full test suite and dark mode. Please feel free to take a look and provide feedback if you have a moment to spare. Thank you!

Hi, Philip here from Tiptap. We just released a new set of open source UI components for Tiptap (https://tiptap.dev/), our headless text editor framework. These are handcrafted React components that integrate directly with Tiptap’s headless core, things like toolbars, dropdowns, formatting buttons, upload controls, etc. They’re MIT licensed and fully optional. You can use them as-is or customize every part. There’s also a CLI that sets everything up for you: project scaffolding, recommended defaults, and a working example. This is for folks who like the flexibility of Tiptap…
