Framework7

Framework7 is a free, open source framework for building mobile and desktop-style apps that look native. It is released under the MIT license and can also be used as a fast prototyping tool.

Framework7 provides ready-made interface parts such as lists, tabs, dialogs, popups and side panels. These are styled to feel like iOS or Android. It works with plain HTML, CSS and JavaScript, and it also has components for Vue, React and Svelte. You can use it for web apps and progressive web apps, and pair it with tools such as Electron for desktop builds.

• Styles that match iOS and Android
• Ready-made lists, tabs, dialogs and forms
• Components for Vue, React and Svelte
• Command line tool to start new projects
• Icon set, templates and plugins

Framework7 suits developers who want mobile-style web apps without learning a large new stack. It also helps teams that need working prototypes quickly, and people who already know HTML, CSS and JavaScript.

The framework is free and open source under the MIT license. Your main costs will be hosting, app store fees and any paid tools you add. Device features are usually added through plugins or through a wrapper such as Electron, so check that the plugins you need are available.
