Open Claude with one small idea.

Not a startup.

Not a big SaaS platform.

Just one tiny app that solves one tiny problem.

That is the best way to start.

Your first app should not need a login system, payment page, database, backend, or complicated setup. Those things can come later. The first goal is simpler:

Build something that works.

Click it.

Break it.

Fix it.

Share it.

That is where Claude is useful. You can describe the app in plain English, let Claude build the first version, then keep shaping it until it feels right.

For the free path, we will use Claude Artifacts. This is the easiest place to start because Artifacts work inside Claude, can create single-page apps, and are available on the Free plan. Anthropic’s own help docs say Artifacts are supported on Free, Pro, Max, Team, and Enterprise plans, and they can create things like single-page HTML websites and interactive React components.

Claude Code is powerful too, but that is not the free-first path. Official Claude support says Claude Code access is tied to Pro and Max plans for individual users.

So this guide is honest:

Start free with Claude Artifacts.

Move to Claude Code later when the app becomes bigger.


The small app we are building

We will build a simple Daily Focus App.

It will have:

  • a task list

  • a focus timer

  • a mood check-in

  • saved data in the browser

  • a clean mobile-friendly design

  • a public link you can share

This is a perfect first app because it teaches the basic parts of almost every small app:

input, buttons, state, storage, layout, testing, fixing, and sharing.

No server.

No API key.

No payment.

No setup headache.

Inside the full guide, I walk through the exact way to build your first free Claude app from a small idea to a working link: how to write the app brief, the first prompt to paste, how to test it, fix one thing at a time, make it look less AI-made, add useful features, save data with localStorage, publish it from Claude, host it later with GitHub Pages, Netlify, or Vercel, and know when to move from simple Artifacts to Claude Code with CLAUDE.md, Git commits, and safer build habits.
