Open-source UI platform for developers

Watermelon UI is an open-source platform for browsing React components, animated interactions, dashboards, templates, and reusable page sections. The project is built for the community and helps developers move from inspiration to implementation faster by pairing visual previews with source-backed examples and documentation. The platform also includes full templates so people can see how individual blocks work together as realistic product pages instead of only as isolated snippets.

Important public pages include the main docs home, animated components, blocks, dashboards, templates, developer docs, about, contact, privacy, terms, copyright, llms.txt, and the sitemap. The repositories under WatermelonCorp are the source of truth for contributions, and the platform repository includes local MCP tooling for structured agent access to the catalog.
