- Webflow lets you design and develop websites in your browser and at whatever level of fidelity you want. And because it was built to help you actually build production-ready, responsive websites, your prototypes can include animations, interactions, actually usable forms, etc. — and anyone can open them on any device to get the full experience.
Really love Balsamiq Mockups 3 - it's helped me build some awesome products. The shortcuts are super convenient and thorough, which makes prototyping like playing the piano. Amazing!
Ah! one shortcut I wish for - flip focus between objects on the workspace and the context menu (right) where I change sizing parameters.
