Framework7 is a free and open-source front-end framework designed to help developers build mobile, desktop, and web applications that look and feel like native iOS and Android apps using HTML, CSS, and JavaScript.

It provides a rich set of prebuilt UI components, navigation patterns, and interaction behaviors that mimic platform-specific design systems while remaining flexible and extensible.

Framework7 also supports integration with popular UI libraries and frameworks such as React, Vue, and Svelte, making it suitable for both traditional hybrid app development and modern component-based workflows.

Key features include:

• Comprehensive set of UI components (dialogs, popovers, lists, tabs, side panels, forms, cards, etc.) for building interactive interfaces.
• Support for responsive layouts and touch-optimized interactions across mobile and desktop.
• Integration with React, Vue, and Svelte ecosystems through official component bindings.
• Built-in CLI tooling and templates for rapid project scaffolding.
• Plugin ecosystem and community templates for extending functionality.

Common use cases include building hybrid mobile applications, progressive web apps (PWAs), and prototypes that need a native-like user experience without deep native development.

Framework7 is maintained as an open-source project under the MIT license, with a community of contributors and an ecosystem of tools and plugins.
