I Built BriefStack.dev in a Weekend with AI (No Vibe Coding)

I built BriefStack.dev - a daily newsletter that curates AI dev tool news from X so you don't have to doom scroll. Built in a weekend using Claude, Next.js, Vercel, and Resend. In this video I break down the full architecture, AI workflow, and key decisions — no vibe coding, no hand-waving. Just real system design with AI as a tool. 🔗 Try it: https://briefstack.dev Stack: Next.js, Claude (Vercel AI SDK), Neon, Drizzle, Resend, Vercel Cron, X API, shadcn, Storybook TODO: Chapters 00:00 Introduction 00:40 PRD breakdown 02:20 Sequence diagram 02:55 AI workflow 03:20 Key services 03:32 Key libraries 03:56 Showcasing the build Music: First Rain by Tokiwave https://soundcloud.com/tokiwave License: Creative Commons — Attribution 3.0 Unported — CC BY 3.0 Free Download / Stream: https://audiolibrary.com.co/tokiwave/first-rain Music promoted by Audio Library: https://youtu.be/Ot9187kyNpM Music: Apollo 11 by Wanheda https://soundcloud.com/user-724527508 License: Creative Commons — Attribution 3.0 Unported — CC BY 3.0 Free Download / Stream: https://audiolibrary.com.co/wanheda/apollo-11 Music promoted by Audio Library: https://youtu.be/Ot9187kyNpM?t=273 Tags: ai coding, build with ai, claude ai, saas development, indie hacker, solo developer, nextjs project, vercel ai sdk, ai workflow, no vibe coding, ai dev tools, build in public, saas in a weekend, newsletter saas, ai agent workflow, claude code, side project, web development, typescript, fullstack development
