vex is a lightweight (~5.6kb) vanilla JavaScript dialog library for creating highly configurable, easily stylable modal dialogs. It serves as a drop-in replacement for native alert, confirm, and prompt with smooth animations, theming, and mobile support.
Use cases
- replace native alert confirm and prompt with styled modals
- show customizable modal dialogs in a web app
- create login or prompt dialogs with custom themes
- open multiple stacked dialogs and close them independently
- add animated modal popups that work on mobile devices
When to choose
- you need a tiny dependency-free dialog library in vanilla JavaScript
- you want full control over dialog styling, themes, and animations
- you need broad legacy browser support including IE9
- you want a drop-in replacement for alert, confirm, and prompt
When to avoid
- you are using a modern framework with its own dialog ecosystem (e.g., React or Vue component libraries)
- you need accessibility-audited dialogs with active maintenance
- you require advanced features like focus trapping guarantees or complex nested workflows
