LogoAI is a Next.js-based web application that enables users to generate professional logos using AI models. The system provides authentication via Clerk, rate limiting through Upstash Redis, and stores generation history in a PostgreSQL database using Drizzle ORM. Users can create logos with customizable styles, colors, and AI models, then view their generation history or browse a public gallery of all generated logos. The application follows modern Next.js patterns with the App Router, server actions for data mutations, and a component-based UI using Shadcn UI primitives.
