Lintapple
Lintapple is a development tool that checks for common user interface mistakes that artificial intelligence overlooks when building frontends.
Lintapple is a development utility designed to prevent artificial intelligence from generating poor user interfaces. It checks for common frontend mistakes that AI models often overlook during the building process. Users install the tool in their projects and configure it for application URLs, fonts, and text sizes. It inspects typography for stable numbers and consistent text sizes. It evaluates layout rules like aligned totals, matching corners, larger controls, and proper spacing around actions. Additionally, it checks color for readable labels and content for contained text.
