Build UIs & Learn to Code

webdevpuneet.com is a free home for frontend developers and anyone learning to code. In one place you get 2063+ copy-paste UI snippets, 25 interactive coding playgrounds with structured lessons, 62 free developer tools, a personal online code editor and a blog of practical tutorials. Everything runs in your browser: there is nothing to install, no account to create, and your code never leaves your device.

Use it when you need a component today, when you are learning a language or framework, or when you want a quick tool to generate, format or convert code. Each part of the site is described below.

UI Snippets: 2063+ copy-paste HTML, CSS and JavaScript components

The UI Snippets library is a collection of ready-to-use interface components written in plain HTML, CSS and vanilla JavaScript — buttons, cards, hero sections, navigation, modals, forms, loaders, animations, layouts, tables, dashboards, games and much more. Every snippet opens in a live editor where you can change the HTML, CSS and JS and see the preview update as you type, check it at mobile, tablet and desktop widths, and copy it in one click.

Because projects use different stacks, every snippet also exports to React (JSX), React + Tailwind CSS, a standalone Tailwind HTML file, a Vue 3 single-file component and an Angular standalone component, and a built-in export tester renders each version live so you can confirm it works before you download it. Each snippet has its own page with the full source code, a screenshot, how it works and FAQs. Browse by category or tag, or search all 2063+ from the box at the top of this page.

Learn to code: 25 interactive playgrounds

The Learn to Code playgrounds teach by doing. Each one pairs short lessons with a live editor and an instant preview, so you change real code and see what happens instead of watching a video. On the frontend there are playgrounds for HTML (42 lessons), CSS, SCSS (45 lessons), JavaScript (60 lessons), TypeScript, Tailwind CSS, Bootstrap 5 (50 lessons), jQuery (72 lessons), React, Vue.js (40 lessons), Angular (45 lessons), Next.js, GSAP and SVG (44 lessons).

For the backend and data side there are playgrounds for Node.js, Express, Python, PHP (60 lessons), SQL with a real PostgreSQL engine in the browser, MongoDB, Redis, GraphQL, Firebase, Git (43 lessons) and a REST API builder. Progress is saved in your browser automatically, so you can close the tab and continue exactly where you stopped.

62 free developer tools

The developer tools handle the small jobs that shouldn't need a new package. CSS generators build layouts and effects visually with a live preview — the Flexbox Builder, CSS Grid Builder, Gradient Generator, Box Shadow Generator, Glassmorphism Generator, CSS Animation Generator and many more — and component builders such as the Responsive Navbar Builder design a whole navigation bar with dropdowns and a mobile menu. Code tools format and validate JSON, XML, SQL and HTML, convert HTML to JSX or JSON to TypeScript, compare text with a diff checker and test HTTP APIs, while the Color Contrast Checker checks WCAG accessibility and AI Prompt Studio helps you write better prompts. Most generators export plain CSS, Tailwind, SCSS or a React or Vue component. The CSS Tools page lists just the CSS generators.

My Code and Fork & Edit

My Code is your own free online code editor for HTML, CSS and JavaScript. Write a snippet from scratch or save any UI snippet into it, edit it with a live preview, and it stays saved in your browser — with an optional private GitHub Gist backup to sync across devices. When it is ready, export it as a standalone HTML file or a React component. Fork & Edit buttons on blog demos and on tools like the Navbar Builder open the result straight in My Code, so you can keep building where the demo or tool stops.

The blog: tutorials with live demos

The webdevpuneet.com blog publishes practical front-end guides — CSS Grid vs Flexbox, container queries, the :has() selector, fluid typography with clamp(), learning to code in the age of AI, and complete guides to the tools on this site. Every article includes live, interactive demos you can open, read the source of, and fork into My Code.

Private, free and built for the browser

Everything on webdevpuneet.com runs client-side. Snippets, playgrounds, tools and My Code process your code on your own device, and lesson progress and saved snippets stay in your browser's storage. There is no sign-up, no paywall and no usage limit, and the site works in every modern browser on desktop, tablet and phone.
