Gradient Builder

Gradient Builder makes gradients from a description or a handful of colours. Ask for "a calm sunset background for my phone" or "a dark animated hero section like the northern lights", and Claude picks the colours and a style, then gives you a link. The link opens the finished gradient in the free Gradient Builder studio at feralui.dev, where you can adjust it and export it as PNG, JPG, SVG, CSS or a looping MP4.

What you can ask for:

• A gradient in any of 27 styles, including Mesh, Aurora, Silk, Flow, Glassy, Prism and Mist. Many of them animate.
• Colours from an archive of 102 traditional Japanese colours, searchable by name, colour family or nearest hex code
• Any of 62 ready-made gradients to open and remix
• A canvas shape: square, portrait, story (9:16) or wide (16:9), with optional film grain
• Ready-to-paste CSS for linear and radial gradients

No account, sign-in or payment needed. The connector is read-only: it receives only the colours, style and title Claude sends, and never sees your messages, files or identity.
