# WebDIY > WebDIY is an AI app builder: describe an app in a chat, and WebDIY writes the code, runs it in a live preview and publishes it, with a database, sign-in and hosting built in. ## Pages - [Home](https://web.diy/index.md): What WebDIY is and how a build goes, with the plans and common questions. - [Product](https://web.diy/product.md): What every project has built in: an agent that builds, runs and tests the app, a database, sign-up and login, one-click publishing with custom domains, analytics, keys and secrets, and teams. - [Pricing](https://web.diy/pricing.md): Free, Pro and Max side by side, and how credits pay for building, running and hosting an app. - [Sign up](https://web.diy/signup): Create a free account; no card needed. ## Docs - [Build and publish your first app](https://web.diy/docs/get-started/quickstart.md): Build your first web app by chatting with WebDIY, try it in the Preview and put it online at its own address. - [Write a good first prompt](https://web.diy/docs/get-started/first-prompt.md): How to phrase your first message, with examples and how WebDIY asks you questions before it builds. - [Find your way around](https://web.diy/docs/get-started/find-your-way-around.md): Learn your way around WebDIY, from managing projects to building, previewing, and publishing apps. - [Your app's database](https://web.diy/docs/database/overview.md): Add a Postgres database to your app. Browse its tables, export a table as CSV and see every change WebDIY makes to it. - [Add sign-in for your app's users](https://web.diy/docs/database/app-sign-in.md): Let people sign up and log in to your app with an email code or a password.
