Stop wasting time and speed up your development workflow with the perfect browser for web developers and designers

Making your site truly responsive and accessible is hard. The most popular web browsers available have their limits for development and designing purposes. Unless you can use a proper native mobile browser you will never be able to simulate the real devices, sync the scrolling position, take full-page screenshots, and see where the bottlenecks are.

Sizzy is a browser made specifically for responsive development and designing. It helps you to make your site responsive, fast, and accessible while speeding up your development workflow by 5x and making sure your site looks perfect on all devices. 

This tool has some brilliant features that will make your panic about testing your website on multiple platforms a thing of the past.

So, let’s check it out.

Never resize your browser again

Emulate real devices, use your responsive CSS breakpoints or pick your own dimensions. No resizing needed.

Everything is in sync

Your keyboard and mouse interactions are synced between all viewports. Scroll, click, or navigate to a different url, and all the devices will follow.

Take beautiful screenshots the proper way, fast & easy

Take a screenshot of the current viewport, or the entire website. You can also screenshot all devices at once. With, or without a device frame. So many possibilities!

Inspecting element on all devices and sizes at once

Inspecting devices one by one can be a chore, so Sizzy includes Universal Inspect Element which allows you to inspect all devices at once. Nice, right?

Realistic devices and device simulation, fully customizable

Sizzy has the most accurate device simulation. It simulates the device frame, the UI for the browser & OS, and you can completely customize everything.

Design and edit directly from the browser

Toggle the Design Mode plugin and easily edit the content of your page, directly from the Sizzy browser.

Founder’s Note

Hi, I'm Kitze! I created Sizzy as a web app in 2017 to help me with one of my landing pages. I quickly bumped into the limits of the web platform and realized that unless it's a proper native browser it will never be able to simulate the real devices, sync the scrolling position, take full-page screenshots, etc.

We have further developed and made Sizzy into a must-have for designers and developers.

Next to Sizzy, I created Twizzle, JSUI, OK Google, Lucky Retweet etc. I founded React Academy to teach React & GraphQL around the world. I also make YouTube Videos and stream on Twitch.

We hope you like Sizzy!
