Proto.io vs Typostrap: What are the differences?
Developers describe Proto.io as "Build high-fidelity fully interactive mobile app prototypes in minutes". Proto.io supports all the major mobile gestures and touch events like tap, tap-hold, swipe, pinch, and zoom. Interaction designers are not limited to a single ‘link’ transition anymore. Instead they can apply animated screen transitions like slide, fade, pop, flip, flow, and turn. On the other hand, Typostrap is detailed as "Rapid prototyping tool for planning and building interactive prototypes. Powered by TYPO3 Neos CMS and Foundation framework". Typostrap is a rapid prototyping tool for planning and building a working concept of your website or application. Typostrap is built on top of a modern, UX-focused Content Management System, TYPO3 Neos and the most advanced responsive front-end framework, Zurb Foundation. Having TYPO3 Neos on board gives you power and flexibility of a Content Management System and makes your prototypes fully interactive, with real behaviour, real content and working interactions. Zurb Foundation brings a responsive grid and all necessary components to build your product quickly and easily. It is the black belt in prototyping.
Proto.io and Typostrap belong to "Interactive Mockups" category of the tech stack.
