Build a directory website builder where users pick a niche (restaurants, SaaS tools, freelancers, JSON categories) and the platform generates a searchable, filterable directory site. Include: listing submission form with custom fields per category, search and filter sidebar (by location, rating, tags), listing detail pages with photos and contact info, featured listing slots for monetization, SEO-friendly URLs and meta tags for each listing, and an admin dashboard for approving or rejecting submissions. Users should be able to customize the directory theme colors and add Google Maps integration.
