uiGradients is a community-maintained, open-source repository of named multi-color gradients with CSS code snippets, distributed under the MIT license. It provides a web interface for browsing, previewing, and copying color gradients from a crowdsourced collection stored as a static JSON file.
The project distinguishes itself through a file-based contribution workflow where new gradients are added by editing a single JSON file and submitting a pull request, relying on Git for version control. Gradients are accessed via named preset lookup, and their CSS code can be copied directly to the clipboard using the browser's Clipboard API.
The collection includes a curated library of gradient presets that can be browsed visually and applied to web design projects by referencing the gradient name and its color stops from the JSON data store. The MIT license permits free use, modification, and distribution of the gradient collection with only copyright notice retention.
