Build an app in 3 bricks

Click the bricks in any order you like: they stack up in the screen, without a line of code.
🧱 Available bricks
📱 Your app
Empty — click a brick
🎉 Well done, your app exists! You've just assembled a title, a list and a button — a real interface — without writing code. That's exactly what no-code is: building by handling visual blocks.
What this teaches you

Assemble, don't type code

🧱 Visual bricks

Title, button, list, form… Each brick already does something. You drop them and configure them with the mouse.

⚡ Faster, cheaper

What used to take weeks of dev takes a few hours. Ideal for testing an idea without hiring a developer.

What to remember

  • No-code = building an app/site without writing code, by assembling bricks.
  • Each brick (title, button, list…) already does something.
  • Advantage: fast and cheap for testing an idea.
