Html5 Ui Design Tool Open Source

Bootstrap Studio is a powerful desktop app for designing and prototyping websites.

It comes with a large number of built-in components, which you can drag and drop to assemble responsive web pages. The app is built on top of the hugely popular Bootstrap framework, and exports clean and semantic HTML.

The Interface

Bootstrap Studio has a beautiful and powerful interface, which is built around the simplicity of drag and drop. This makes it the perfect tool for prototyping and designing web pages and apps.

Beautiful Templates

The app comes with a number of premium, fully responsive templates that you can customize. Each template consists of multiple pages and widgets you can pick-and-match into the perfect website.

Beautiful Components

Bootstrap Studio comes with a large number of pretty components for building responsive pages. We've got headers, footers, galleries, slideshows and even basic elements like spans and divs. See some of them below.

Smart Drag & Drop

Bootstrap Studio knows which Bootstrap components can be nested in one another and gives you suggestions. It automatically generates beautiful HTML for you, which looks as if it was written by hand by an expert.

Create Your Own Components

You can extract pieces of your designs as Custom Components, and have them ready to be dropped into any design you create. You can also export these components as files and share them.

Online Library

If you need a component which doesn't exist in our library, just click the Online tab in the Component Panel. There you will find thousands of components built and shared by the community. You can also upload your own.

Linked Components

This is a powerful feature which allows you to synchronize components, so changing one will automatically change the other. This is especially useful for things like headers and footers which you need to update across pages.

Realtime Preview

Bootstrap Studio has a powerful feature called Preview. With it, you can open your design in multiple web browsers and devices, and every change you make within the app will be shown instantaneously everywhere.

Browser Preview

Editing Code

For some things drag and drop isn't enough. This is why Bootstrap Studio gives you full control over your markup when you need it. You can import and edit CSS, SASS, JavaScript and HTML in our Sublime Text-like editor.

CSS Editing

Advanced CSS and SASS Editors

Our advanced CSS editing interface supports auto suggest and rule validation, and shows the active and inherited rules at an any given time.

JavaScript Editing

Write JavaScript in our Sublime Text-like editor. All your changes are synced with the preview, so you can write code and try it out without having to reload your browser.

HTML Editing

With our powerful Custom Code component, you can write HTML directly, without going through our drag and drop interface. You can also convert any piece of your page into Custom Code when you need it.

Import Existing Websites

If you have a website that you've developed previously, you can import it. Just drag and drop the HTML, CSS, JS files and images into Bootstrap Studio and they will be added to your project.

Connect External Editors

Prefer to write CSS in your editor? No problem! With a single click you can connect Visual Studio Code, Sublime Text, Atom, IntelliJ and more.

Keyboard Shortcuts

Bootstrap Studio has comprehensive support for keyboard shortcuts which allow you to speed up your workflow dramatically.
