Platform Overviews
Lovable
Lovable (formerly GPT Engineer) is a full-stack AI application builder that creates complete React web applications — including frontend, backend logic, and Supabase database — from natural language prompts. Unlike website builders that produce marketing pages, Lovable builds interactive applications with user authentication, real-time data, and API integrations. It's used by startups and developers to rapidly prototype SaaS products, internal tools, and web apps that would otherwise require a development team. Lovable has surpassed 1 million users and powers thousands of production applications. Sites can be detected through requests to lovable-uploads.s3.amazonaws.com for stored files and *.lovable.app domains for hosted projects. Pricing starts free with a usage cap, and Pro plans begin at $20/month.
Vercel
Vercel is the cloud platform and deployment infrastructure behind Next.js — founded by Guillermo Rauch, the creator of Next.js — serving as the premier hosting platform for React, Next.js, and Jamstack applications globally. Vercel's edge network spans 100+ regions worldwide and powers some of the world's highest-traffic web applications, offering automatic scaling, preview deployments for every Git branch, and analytics. It's the deployment platform of choice for teams using Next.js, Remix, Astro, SvelteKit, and other modern frameworks. Sites hosted on Vercel are identifiable through x-vercel-id and x-vercel-cache HTTP response headers, server: Vercel, and *.vercel.app subdomains for preview and hobby deployments. The cf-ray header is absent on Vercel (distinguishing it from Cloudflare-hosted sites). Vercel Hobby plans are free, with Pro plans at $20/month per member.
