For Developers — Faster Code, Fewer Errors
The standard for modern CSS gradients. Generate production-ready CSS in seconds, integrate directly into your workflow with our VS Code extension and REST API.
Install VS Code Extension Read the API DocsDesign, generate, ship — without leaving your editor
Stop wrestling with vendor prefixes, color interpolation modes, and calc()-based angle math. KleurFlow handles the complexity so you can focus on building interfaces that ship.
Our VS Code extension (12,400+ active installs) adds a command palette entry that opens the gradient editor inline. Pick your colors, adjust the angle slider, toggle linear versus radial, and hit Ctrl+Shift+G — the CSS drops directly into your stylesheet. No copy-paste, no context switching. The generated output includes automatic vendor prefixing for -webkit-gradient, correct color-stop syntax, and fallback solid-color declarations for legacy browsers.
For team workflows, the REST API accepts a JSON payload with color arrays, angle, type, and direction properties, returning minified CSS, a PNG preview, and a shareable URL. Engineering teams at Vercel, Linear, and Framer use it in their CI pipelines to validate design-token consistency across components before merge.
Production-ready CSS, zero guesswork
Every gradient KleurFlow generates passes through our linter. You get valid, accessible, performant CSS — guaranteed.
Linear Gradient — 3-Stop
background: linear-gradient(135deg, #667eea 0%, #764ba2 50%, #f093fb 100%);
Generated in 0.03 seconds. Includes automatic -webkit- prefix for Safari older than 12.1. Lighthouse contrast score: 4.8:1 against white text.
Radial Gradient — Elliptical
background: radial-gradient(ellipse at 30% 20%, #00c6ff 0%, #0072ff 60%, transparent 100%);
Optimized for hero sections. Fallback background-color: #0072ff; injected automatically for IE11 support.
Conic Gradient — Dashboard Ring
background: conic-gradient(from 180deg at 50% 50%, #26d07c 0deg, #e2b714 120deg, #fc5c65 240deg, #26d07c 360deg);
Used by 3,200+ developers for progress indicators and data viz. Masked with mask-image for ring shapes.
Why front-end teams switch to KleurFlow
Built by developers, for developers. Every feature exists because someone filed a GitHub issue asking for it.
Save 11 Minutes Per Component
Our usage analytics across 8,700 active developer accounts show an average of 11 minutes saved per gradient-heavy component. That's roughly 2.3 hours per sprint for a team of four engineers.
Zero Syntax Errors
KleurFlow's output is validated against the CSS Snapshot 2023 spec before rendering. In 2024, our code-generation engine produced zero syntax errors across 1.4 million gradient requests. Compare that to manual coding, where a misplaced comma breaks the entire background.
VS Code Native Integration
The extension (published as @kleurflow/vscode-gradient) adds inline preview, Emmet-style shortcuts, and a gradient abbreviation: g>linear@135 expands to a fully-prefixed gradient with your current palette. Works with Tailwind, SCSS, and plain CSS files.
API for Automation
POST to api.kleurflow.dev/v2/generate with a JSON body. Get back CSS, a 512x512 PNG, and a permanent URL. Rate limit: 1,000 requests per hour on the free tier. Teams at Stripe and Notion use it to auto-generate gradient backgrounds from their design tokens during build time.
Design Token Sync
Import your tokens from Style Dictionary, Figma Variables, or a JSON file. KleurFlow maps gradient color stops to your token names, so --color-primary-500 stays consistent across your entire codebase. No more hardcoded hex values in gradients.
Accessibility-First Output
Every generated gradient includes a WCAG 2.2 contrast check. If text readability falls below AA (4.5:1), KleurFlow suggests a darker stop or a semi-transparent overlay. Your gradients look great and pass audit tools on the first try.
