Responsively

Responsively is a developer tool simplifying responsive web design testing. It lets you preview websites across multiple device screens simultaneously with synchronized interactions (clicks, scrolls, form inputs). Features include live reloading for instant updates, browser dev tools integration for debugging, customizable device presets, and offline functionality. Ideal for front-end devs and designers, it streamlines cross-device workflows, reducing time spent switching between tools to ensure consistent experiences across all screen sizes.
