Tailwind JIT CDN is a browser tool that loads Tailwind CSS's JIT compiler into any HTML page via a single script tag, enabling utility-first styling without a build step.
What is Tailwind JIT CDN?
Tailwind JIT CDN is an open-source script that runs Tailwind's new JIT compiler directly in the browser. By including the script tag https://unpkg.com/tailwindcss-jit-cdn in your HTML, you get on-demand generation of Tailwind utility CSS without needing Node.js, npm, or a PostCSS configuration. The project was created by Marcel Pociot and is maintained by Beyond Code, and it is released under the MIT license.
Key Features
- Single script tag setup — Add one script element to your page and the JIT compiler is active; the package is hosted on unpkg.
- In-browser compilation — Tailwind utility classes are processed client-side, so you see the resulting styles immediately without a build step.
- No configuration files — Works with plain HTML and CSS; no tailwind.config.js, postcss.config.js, or bundler required.
- Free and open source — Licensed under MIT, allowing unrestricted use in commercial and personal projects.
- Supported by an in-depth blog post — Beyond Code published a detailed article explaining how the package works and how to use it.
- Built by active maintainers — Marcel Pociot and contributors manage the project as part of Beyond Code's free developer services.
Who is it for?
- Front-end developers who want to prototype a Tailwind layout in a single HTML file without setting up a full toolchain.
- Static-site creators who need to add Tailwind styling to a one-off page or snippet and prefer a drop-in script.
- Tailwind learners who want to experiment with utility classes and see the generated CSS instantly in the browser.
What can you do with Tailwind JIT CDN?
- Prototype a page quickly: Insert the script tag into a blank HTML file and start adding Tailwind classes to elements right away.
- Style standalone files: Apply Tailwind utilities to a static HTML document such as a landing page, email preview, or documentation excerpt.
- Evaluate generated CSS: Use the browser's inspector to see which utilities are produced for your markup and verify Tailwind's JIT behavior.
How does Tailwind JIT CDN work?
Include the script tag in the head or body of your HTML. When the page loads, the script fetches the Tailwind JIT compiler from unpkg, scans your markup for class names, and injects the resulting compiled CSS as a style tag. The output replaces the need for a separate CSS build pipeline.
Pricing
