Build a small web app with no code

You can now build a real, working web app without code — the AI writes it from your description and puts it online. The only trap is doing too much. Build the smallest version that does one job, use it, then add more.

Begin with a tool that does exactly one job, described in a single sentence — a tracker, a form that emails you responses, a simple calculator. Have AI walk you through it and check each step works before moving on. Seeing your own working software run is the moment it clicks.

Once v1 runs, resist adding features. Use the ugly version yourself for a few days — real use, not imagination, should pull your roadmap. You'll discover the actual next feature is something you'd never have prioritised, and half the features you imagined are unnecessary. Add the next thing only when its absence is genuinely annoying.

As it grows you'll hit no-code's edges — performance, sensitive data, logic the platform can't express. Recognise those and decide deliberately: stay simple, or graduate (and maybe hand a developer your working prototype as the clearest brief imaginable). Most tools never need to graduate; the ones that do have already earned it.

1. 1Write one sentence: the single job this tool does.
2. 2Describe it to the builder and let it generate the first version.
3. 3Use it yourself for a few days before adding anything.
4. 4Add the next feature only when its absence is genuinely annoying.
