Why I Built This

As a developer, I constantly faced these challenges:

• Repetitive Work: Building the same components over and over for different projects.
• Inconsistency: Lack of design consistency across projects and teams.
• Accessibility Gaps: Difficulty implementing proper accessibility in every component.
• Time-Consuming: Spending too much time on UI instead of core functionality.
• Poor Documentation: Existing libraries with inadequate or confusing documentation.
• Customization Limits: Hard to customize components to match brand guidelines.

DevUI solves these problems by providing a complete, well-documented, and easily customizable component system.
