Sizzy
Test responsive designs faster with this browser built for web developers
It’s almost funny that you’re trying to build a super fast website when your own browser is weighed down by 70 open tabs. (“Trust me, closing them would also slow me down.”)
With all your work spread across multiple devices, browsers, and conditions, you’re bound to make a mistake and give some bad actor the power to break your site.
Wish there was a browser created specifically for web development that let you access all your tools from one place?
Introducing Sizzy.

Overview
Sizzy is a web browser made specifically for responsive development that lets you handle all your web dev needs from one window.
Save time testing
With just one click, Sizzy lets you preview your websites on different screen sizes and devices simultaneously.
- Sync your window navigation across devices, from clicks to scrolls to zooms
- Align your device windows in horizontal, vertical, grid, or float mode to suit your screen setup
- Customize the settings for every device including border color, browser, and OS
Test your website or app on multiple devices at once.
Full suite of web developer tools
Say goodbye to downloading random Chrome extensions! Sizzy comes packed with a suite of tools for front-end developers right in the box.
- Access tools like API inspector, session manager, and CSS overrides inside your browser
- Disable certain web features like animations, transitions, and GIFs for better performance
- Enable split viewing to see multiple browser tabs at once
Access every tool a front-end developer could dream of right out of the box.
Smooth context switching
Even better, Sizzy lets you organize tabs, notes, bookmarks, API requests, and code snippets into separate projects.
- Switch to any project to find all your tools right where you left them
- Use Zen Mode to hide everything except the project you’re currently working on
Separate your work into projects that will load exactly as you left them.
Create professional screenshots
Thanks to its advanced algorithm, Sizzy can take high-quality screenshots of your website without broken styling or bugs.
- Take scrolling, full-page screenshots of any website
- Move and resize your devices on a free canvas, choose a background, and take a screenshot or video for easy reference
Take high-quality screenshots of your site on multiple devices with ease.
Sizzy gives you everything you need to simplify your web development workflow, from simultaneous testing across multiple devices to project organization.
