Introducing Tailwind Config Generator: Build Your tailwind.config.js Visually

We built a free visual Tailwind CSS config generator. Set your brand colors with a color picker, configure font families, adjust breakpoints, and toggle plugins — then copy your complete tailwind.config.js in one click. Supports both Tailwind CSS v3 and v4. No login. No install.

What Is a Tailwind CSS Config File?

A tailwind.config.js (or tailwind.config.ts) is the customization layer of Tailwind CSS. It tells Tailwind:

• Where to scan for classes (content paths) — so unused CSS gets purged
• What to add to the theme (theme.extend) — custom colors, fonts, spacing, breakpoints
• Which plugins to load — forms, typography, aspect-ratio, line-clamp

For Tailwind v4, the configuration moves into CSS itself using an @theme block in your stylesheet. Different syntax, same purpose: tell Tailwind what's custom about your project.

Why Does This Tool Exist?

Every Tailwind project has the same five-minute tax at startup: copy a config template, replace the placeholder values, remember the exact theme.extend nesting, look up whether the plugin needs require() or an import, wonder if the content glob is right for your project structure.

For a senior developer on their tenth project, this is muscle memory. For someone learning Tailwind, onboarding to a team, or scaffolding a new product quickly, it is friction that slows you down before you've written a single component.

The generator removes that friction. Configure visually, copy once, done.

How Does the Tailwind Config Generator Work?

How do I add custom colors to my Tailwind config?

Open the Colors tab. Click Add Color to add a new entry. Use the color picker to select your brand color, type its name (e.g. primary, brand, accent), and see the hex value auto-populate.

For v3, the generator outputs:

theme: {
  extend: {
    colors: {
      primary: "#3b82f6",
      brand: "#6366f1",
    },
  },
},

For v4:

@theme {
  --color-primary: #3b82f6;
  --color-brand: #6366f1;
}

Add as many colors as your design system requires.

How do I set custom font families in Tailwind?

Open the Fonts tab. The generator exposes sans, serif, and mono font stacks. Each field takes a comma-separated list of font names — the same format you'd write by hand.

Enter Inter, ui-sans-serif, system-ui for sans and the generator produces the correctly formatted Tailwind font array. You don't need to remember whether it's an array of strings or a space-separated string.

Can I customize Tailwind breakpoints?

Yes. Open the Breakpoints tab. The default Tailwind breakpoints are pre-filled (sm: 640px through 2xl: 1536px). Edit any value, rename any key, delete ones you don't need, or add a custom breakpoint like 3xl: 1920px or tablet: 900px.

What Tailwind plugins does the generator support?

The Plugins tab lists the four official Tailwind plugins:

• @tailwindcss/forms — consistent form element styling
• @tailwindcss/typography — the prose class for rich text
• @tailwindcss/aspect-ratio — aspect ratio utilities
• @tailwindcss/line-clamp — line clamp utilities

Click a plugin to toggle it. The generator adds the correct plugin syntax automatically: require("@tailwindcss/forms") for v3, or @plugin "@tailwindcss/forms" for v4.

What is the difference between Tailwind v3 and v4 config?

Tailwind v3 uses a JavaScript config file:

/** @type {import('tailwindcss').Config} */
module.exports = {
  content: ["./app/**/*.{js,ts,jsx,tsx}"],
  theme: {
    extend: {
      colors: { primary: "#3b82f6" },
    },
  },
  plugins: [require("@tailwindcss/forms")],
};

Tailwind v4 moves configuration into CSS using a @theme block:

@import "tailwindcss";
 
@plugin "@tailwindcss/forms";
 
@theme {
  --color-primary: #3b82f6;
  --font-sans: Inter, ui-sans-serif, system-ui;
  --breakpoint-sm: 640px;
}

The generator handles both formats. Switch the version toggle and the output updates immediately.

What Is the tailwind.config.ts Format?

When you select v3 + .ts, the generator produces a TypeScript config with proper typing:

import type { Config } from "tailwindcss";
 
const config: Config = {
  content: [
    "./pages/**/*.{js,ts,jsx,tsx,mdx}",
    "./components/**/*.{js,ts,jsx,tsx,mdx}",
    "./app/**/*.{js,ts,jsx,tsx,mdx}",
  ],
  theme: {
    extend: {
      colors: {
        primary: "#3b82f6",
      },
      fontFamily: {
        sans: ["Inter", "ui-sans-serif", "system-ui"],
      },
    },
  },
};
 
export default config;

This is the format used by most modern Next.js + TypeScript projects.

Who Is This For?

Frontend developers starting a new project who want their Tailwind config set up correctly from the first commit, not patched in later.

Designers who code learning Tailwind who need to understand how custom colors and fonts map to config structure without reading through the full documentation.

Fullstack engineers who set up Tailwind occasionally and always have to look up the exact nesting — theme.extend.colors or just colors? Does screens go in extend or at the top level?

Teams onboarding developers who need to communicate their Tailwind setup quickly. Generate the config, share the URL, done.

Developers migrating from v3 to v4 who want to see how their existing config maps to the new CSS-first format side by side.
