Users

Frontend developers and product designers comparing UI libraries for an active project, plus contributors maintaining the directory.

Product Purpose

Col is a community-maintained directory for finding, filtering, and comparing UI libraries without opening many disconnected sources.

Positioning

Col combines a curated library registry with practical stack and use-case filters, then sends users to the official source for each library.

Operating Context

Visitors search from the homepage, refine results in the library directory, save useful entries locally, and use GitHub issues or pull requests to improve the catalog.

Capabilities and Constraints

• Catalog libraries, and optionally a verified, explicitly partial list of components each library documents.
• Never infer that a library offers a component from its generic tags, and never present component coverage as complete.
• Keep library metadata factual and link to canonical project sources.
• Preserve light and dark themes, keyboard access, responsive behavior, and reduced-motion support.
• Only maintainers merge changes to the protected default branch.

Brand Commitments

The product is named Col and uses the line “Sol could not do it himself, so we made Col.” The visual identity is minimal, high-contrast, and uses #0800FF as its primary accent.

Evidence on Hand

The curated registry lives in data/libraries.ts; verified components live in data/components.ts. Contribution rules live in README.md, CONTRIBUTING.md, and .github/ issue templates.

Product Principles

• Reduce the time it takes to find a suitable UI library.
• Prefer clear filters and factual metadata over promotional copy.
• Keep contributions focused, reviewable, and easy to verify.
• Send users to official project sources for installation and documentation.
