Overview

Slopdar is a web service that analyzes any submitted URL to determine if the website was built using AI generation tools or templates, rather than being hand-crafted. It assigns a 'slop score' from 0 to 100 and provides a humorous 'roast' based on detected AI fingerprints. The service checks for telltale signs such as specific tool markups (e.g., v0, Lovable, Bolt, Replit), default UI components (like Lucide icons and shadcn buttons), common technology stacks (Next.js on Vercel with Supabase), recurring layout patterns (centered hero, gradient blobs, bento grids), and leftover placeholder content. Results are displayed with a detailed breakdown and the site may be featured on a public leaderboard showcasing the week's sloppiest or most hand-crafted sites. Users can also embed a badge on their website to flex a low score or own a high one, with tiers like 'Certified Hand-Crafted' and 'Pure Slop'.
