How I Build Web Apps and SaaS With AI

The web app version of How I Build Professional Websites for Clients With AI. It starts with the line between the two: a website shows everyone the same page, and it becomes a web app once people log in and the data belongs to them. That forces a login, a database, and a server that runs on every request.

Then the whole stack: how I orchestrate the build, what it’s built with, where the code lives, where the data lives and how it’s backed up every night, how it deploys, and the integrations. It ends with the two questions I get most, why Next.js and Vercel instead of the Astro and Cloudflare setup I use for marketing sites, and why I don’t just use Lovable, Replit, or Base44. The whole stack is written down in my web app blueprint, free, no opt-in.
