Gradient Generator

The Gradient Generator is a free, browser-based visual editor for designing CSS gradients and exporting them as production-ready code for web and mobile projects. Instead of writing linear-gradient() or radial-gradient() by hand and guessing at color stop percentages, you build the gradient visually on a large preview canvas and let the tool translate it into clean syntax. It supports the three gradient families used across modern interfaces: linear gradients for backgrounds and buttons, radial gradients for spotlights and glows, and conic gradients for pie-style and angular effects.

Everything runs entirely inside your browser. There is no account, no upload, and no waiting on a server. You drag color stops, adjust an angle dial, set opacity, and the matching code appears immediately in eight different formats covering CSS, Tailwind CSS, Flutter, React Native, SwiftUI, Android XML drawables, Jetpack Compose, and a portable JSON object.

Hand-coding gradients is slow and error-prone because tiny changes to a stop position or angle require re-saving and refreshing to see the result. This tool removes that loop: the preview updates as you drag, so you can dial in the exact look in seconds. It also solves the cross-platform problem that designers and developers hit constantly.

• One gradient, many platforms: A gradient you perfect for a website can be copied straight into a Flutter app, a SwiftUI view, or an Android drawable without re-deriving the colors and stops by hand.
• Precise control: Numeric position and opacity sliders let you place stops exactly where you want them rather than eyeballing percentages.
• No setup: There is nothing to install or configure. Open the page and start designing, even on a phone.
• Readable output: The CSS export includes a solid-color fallback so older browsers degrade gracefully.

Gradients appear everywhere in modern design, and this tool fits a wide range of real workflows:

• Hero section backgrounds: Create a soft two-tone linear gradient at 135 degrees for a landing page header and paste the CSS into your stylesheet.
• Call-to-action buttons: Design a vivid linear gradient, then copy the Tailwind arbitrary-value class to style a sign-up button without touching your config.
• Mobile app screens: Build a radial glow behind a logo and export it as a Flutter RadialGradient or a SwiftUI RadialGradient for an onboarding screen.
• Conic and pie effects: Use a conic gradient to mock up a loading spinner, color wheel, or progress ring, then ship it as a Jetpack Compose sweepGradient.
• Glassmorphism overlays: Lower the opacity on individual stops to produce the translucent fade used in frosted-glass cards.
• Design tokens: Export the gradient as JSON to store it in a design system or feed it into a build script.

A few habits produce noticeably better gradients. First, keep most gradients to two or three stops; adding too many colors muddies the blend and can create visible banding. When you do need a multi-stop gradient, space the stops thoughtfully and use the Position slider to control where one color hands off to the next.

• Use related hues: Colors that sit near each other on the color wheel blend smoothly, while opposite hues can create a dull gray midpoint.
• Mind the angle: The default 90-degree angle runs left to right; 135 degrees gives the popular diagonal look. The small angle dial next to the slider shows the direction at a glance.
• Fade with opacity, not white: To fade a gradient into the background, drop a stop's opacity toward zero instead of adding a white stop, which keeps edges clean over any backdrop.
• Add to gaps: The Add Stop button automatically places the new stop in the widest empty space, so you spend less time repositioning.

The output panel converts a single gradient into eight formats, each tailored to its platform. CSS produces a standards-compliant declaration with a solid fallback. Tailwind emits an arbitrary-value utility class. Flutter generates a BoxDecoration with the matching LinearGradient, RadialGradient, or SweepGradient including stops and ARGB colors. React Native outputs a LinearGradient component with colors and locations, and notes when a type needs an SVG library. SwiftUI returns LinearGradient, RadialGradient, or AngularGradient with location-based stops.

On the native Android side, the XML export writes a drawable gradient with offset items, and Jetpack Compose produces a Brush with color-stop pairs. Finally, the JSON format captures the full gradient definition: type, angle, radial shape and position, and every stop's color, position, and opacity. The editor also adapts the available tabs to the gradient type, hiding formats that cannot represent a given effect natively.

Teams use the Gradient Generator to keep visual styling consistent across a product's web and mobile surfaces. A UI designer can prototype a brand gradient and hand the matching Flutter and SwiftUI snippets to engineers, guaranteeing the iOS app, Android app, and website all render the identical blend. Front-end developers reach for it to skip the trial-and-error of writing conic gradients for charts and indicators by hand.

It also fits design-system work: the JSON export gives a single source of truth for a gradient that can be checked into version control and regenerated for any platform. Marketing and content teams building landing pages benefit too, since they can produce polished hero backgrounds and button styles without a heavyweight design application or any coding knowledge.

Because the tool is entirely client-side, performance does not depend on network speed or server load. The gradient string and all eight code outputs are computed locally in JavaScript the instant you move a slider, so the preview and the snippets stay perfectly in sync with zero round-trip delay. There are no file size limits, no rate limiting, and no queue, no matter how many gradients you generate in a session.

Once the page has loaded it continues to work offline, which means you can keep designing gradients on a flight or with a spotty connection. The lightweight interface runs smoothly on laptops, tablets, and phones alike, and copying a snippet is a single click rather than a manual text selection.

The Gradient Generator is privacy-first by design. Every color, stop, and exported snippet is created and stored only in your browser's memory for the duration of your visit. Nothing you build is uploaded, logged, or transmitted to any server, so your in-progress brand colors and unreleased design work never leave your device. There is no sign-up, so the tool collects no email address or personal information to use it.

This local-only model makes it safe for confidential commercial projects where design assets must not be sent to third-party services. When you close or refresh the tab, your gradient simply clears from memory, leaving no trace behind.

A few recurring errors keep gradients from looking their best. The most common is overcrowding the gradient with too many stops, which produces harsh bands instead of a smooth transition; trimming back to two or three well-placed colors usually fixes it. Another is forgetting that the linear angle is measured in degrees clockwise from the top, so a value that looks wrong is often just rotated, which the live angle indicator helps you catch.

• Skipping the fallback: When using the CSS output, keep the included solid-color fallback line so the design holds up in environments that do not support gradients.
• Mismatched stop order: Stops are sorted by position automatically, but jumbled percentages can still surprise you, so confirm the preview matches your intent.
• Wrong export for the platform: Pick the tab that matches your stack; React Native, for example, needs extra libraries for radial and conic gradients, which the tool flags in a comment.
• Ignoring opacity: Leaving every stop at full opacity misses easy soft-fade and overlay effects.
