TweakCN is a free, open-source visual theme editor designed specifically for shadcn/ui components, a popular set of reusable UI elements for React projects. Its primary goal is to address the common issue of shadcn/ui-based websites looking overly similar by enabling developers and designers to create unique, standout themes without coding.

With support for Tailwind CSS v4, it’s a powerful tool for startups, UI/UX designers, and developers aiming to customize their React applications efficiently. The project has gained traction, reportedly hitting 300 signups in its first week according to posts on X, and is actively maintained on GitHub with a roadmap for future expansion
