I built this entire site in one evening. From zero to Vercel.
Not a prototype. Not a "needs some polish" situation. A working site with a blog, i18n, OG images. Everything.
What the process looks like
You open your terminal. Launch Claude Code. Tell it what you want. It writes code, creates files, makes commits. You watch, give feedback, steer.
This isn't "AI wrote code and I copy-pasted it." It's more like pair programming with a very fast partner who doesn't need you to explain what Next.js is.
My stack
- Claude Code -- Anthropic's CLI tool. Runs right in your terminal.
- CLAUDE.md -- a file with instructions for each project. Rules, stack, structure. Claude reads it and follows it.
- Next.js App Router + Tailwind CSS v4 -- for fast development.
- Vercel -- deploy with a single push to GitHub.
What surprised me
Claude understands project context. If you already built a Nav component and then ask for a blog page -- it reuses that Nav. Doesn't create a new one.
It also follows design systems. I described colors, fonts, spacing in a DESIGN.md file -- and it stuck to them across every component.
Where it makes mistakes
It happens. TypeScript types get wonky sometimes. It might suggest an old Next.js API. Or add as const where it shouldn't and break type inference.
But these mistakes take seconds to fix. You say "hey, the types are broken here" -- and it fixes them.
Who this is for
If you're a founder and need a website -- you can build one yourself in an evening. You don't need to learn React from scratch. You need to know what you want and have the taste to judge the result.
If you're a developer -- Claude Code makes you 5-10x faster. It won't replace you. It'll speed you up.
This is the future. And it's already here.
