Unsave Popup

Buttons 56

About

A popup component to confirm before discarding changes. Inspired by Discord, it will shake when the user tries to leave without saving.

Built with React and Tailwind. Copy the prompt and paste it into Claude Code, Cursor or Lovable: your agent adds Unsave Popup to your project and fits it to your theme.

Code

How Unsave Popup is used: the demo's code. The component's own source comes with a free account.
