Bubble

Bubble is a visual platform for building full-fledged web and mobile applications without writing code. It is made by the company of the same name, which has been building it for over a decade and runs its own product on it. It is meant for founders who do not just want a simple website but a real product with a database, user accounts and custom logic.

You work in a visual editor: drag interface elements onto the canvas, connect them to a database, and in the workflow editor draw out what should happen after a click, a form submission or a payment. The output is a hosted app running on robust infrastructure that you deploy straight away for users.
