We are also working on a completely new debugging experience in Sizzy, so just wait for it πŸ˜‰


Request an extension

Missing a DevTools extension? You don't need to wait for an update anymore. Just click on "Request an extension" in the settings and as soon as we approve it, it's gonna be instantly available in Settings -> DevTools and everyone will be able to install it.

CleanShot 2020-07-24 at 15.59.46.png

For example, we added the XState extension and now it's available for everyone.

Helpful buttons if the page cannot be loaded

It was super annoying to see a blank white page if a page cannot be loaded. Now you're going to see a helpful message along with a "Reload" button. If you currently have an active project, Sizzy will show a button so you can easily navigate to one of your bookmarks that's not on localhost. CleanShot 2020-07-17 at 15.43.12.png

Support command line args for code editor

When adding a custom editor now you can add extra args along with the CLI name. CleanShot 2020-07-17 at 15.51.34.png

CPU & performance improvements

We tried to get rid of all the performance problems, and now the CPU usage in Sizzy should be similar to using any other browser. We also improved the startup time by ~2 seconds (scientifically measured down to the last ms 😎)

However, if your website or web app takes 10% CPU, and you have 10 devices open in Sizzy, you should expect it to multiply its CPU usage by 10. Sizzy will always be resource-hungry because it's the only browser that shows multiple websites at once.

Our advice is to pay attention to animations and transitions in your website, because usually, they are the performance biggest problem, especially if displayed on multiple devices at once.

You can easily toggle animations and transitions in Sizzy with the Debug Styles plugin.

You can read more about improving the performance in Sizzy in our Help Center article.

Custom scrollbars

Styling the scrollbars in Sizzy caused some issues on macOS, so we made the custom scrollbars optional. If you want to show them only when scrolling, you can easily enable that setting in macOS.

CleanShot 2020-06-29 at 20.21.30@2x.png

However, if you want the custom scrollbars back, you can enable them in Settings -> Performance.

More class names for debugging elements

Did you know you can easily debug your elements in Sizzy by adding a "sizzy-[color]-[size]" classes to your HTML elements? You can enable that setting in the Debug Styles plugin.

CleanShot 2020-06-29 at 20.31.35@2x.png

We added new colors so now you have more options for debugging:

  • blue
  • red
  • green
  • black
  • cyan
  • aqua
  • pink
  • orange
  • purple
  • gray
  • yellow
  • brown
  • white
  • magenta
  • maroon
  • navy
  • teal
  • turquoise
  • tomato
  • violet
  • lime

Other changes and fixes

  • The shortcut for toggling the DevTools has changed to Cmd + Option + I on macOS and Ctrl + Alt + I on Windows.
  • Fix: CORS enable/disable doesn’t work
  • Fix: The docked dev tools switch their theme color
  • Fix: The selected device in the docked devtools doesn't change when changing focused device in focused mode

Sizzy 0.24 πŸŽ‰

Sizzy 0.24 is here! 😍

Note: We skipped the changelog for 0.23 because it mostly consisted of bugfixes πŸ›οΈ

Find In Page

Finally, right?! πŸ˜… You can now press Cmd + F or Ctrl + F to search for text in all devices in any mode: Responsive Mode, Full Mode, Focus Mode, etc.

It even works in the Reference Browser tabs πŸŽ‰

We really apologize that this issue took us so long, but there was a bug in Electron that prevented us from shipping it. Let us know if you find any issues with it! πŸ™Œ

Other improvements and fixes

  • Remove headway widget and create a simple replacement widget using webview
  • When ref. browser is docked to the left it cannot be resized unless hovering over sizzy UI elements (hover on the webview doesn't resize)
  • Enable docked devtools by default
  • [Windows] Menu Sizzy -> About Sizzy doesn't show the whole version
  • Universal inspect element doesn't work
  • After going offline -> online a few separate refreshes are needed for the devices to come online
  • Resizing of devtools stops working hovered over a device
  • The "x" button is showing when hovering over a pinned tab
  • Screenshots don't work with a couple of websites

p.s We're working hard towards making the app more stable and we're trying to fix all the issues related to performance. We appreciate your patience πŸ˜‡

Enjoy πŸ™Œ

Sizzy 0.22 πŸŽ‰

Sizzy 0.22 is here! Let's dig in 😍

Keep docked DevTools in memory (Optional)

If you have some power to spare, you can keep the docked DevTools in memory, so when you collapse them (via dragging or keyboard shortcut) and open them again, they won't reload. This saves a bunch of time but it can cost some resources, that's why we disabled it by default.


The docked DevTools are now dark by default

Sizzy has an overall darker UI so it makes sense for the DevTools to be in dark mode by default. You can still switch back to the light mode from the DevTools settings if you prefer it, we won't judge 😜️


Other improvements & fixes

  • Fix: The device individual zoom controls (+ and -) are not working
  • Fix: When the Sizzy Console or the DevTools are manually closed by dragging them to the end, the panel doesn't open properly when it's opened with the ; shortcut

We're working hard on addressing all the CPU/GPU issues with Sizzy and we'll make sure to have a proper solution until the end of this month. We really appreciate your patience and support ❀️

Sizzy 0.21: Docking the DevTools 😱

This is our biggest release ever… Are you ready for it? 😎


Go to Settings -> General and enable Docked DevTools πŸŽ‰πŸŽ‰πŸŽ‰

If it doesn't work immediately just restart Sizzy. This should also fix all the disconnect issues that were randomly occurring when using the DevTools before.

  • You can easily select which device is being inspected
  • You can automatically open the DevTools and navigate to any element in any devices by using the Universal Inspector
  • You can right-click -> Inspect Element in any device
  • You can toggle the DevTools by pressing ;
  • Docked DevTools should work in any mode


You can read more about the Docked Devtools in our Help Center article.

⚠️ This is still an experimental feature so please let us know if you find any issues. We are aware that the DevTools extensions are not working and we're working on a fix. Also, while the DevTools are docked you cannot use the awesome Sizzy Console, but we have a solution for that and we can't wait to show it to you :)

Add X icon for closing the tabs in the reference browser

Opening the menu just to close a tab is annoying, so we added an X button for every tab in. Please let us know if you have more ideas for the reference browser.


Other Fixes

  • The color scheme gets reset when the DevTools for that device are loaded/refreshed

If you cannot update to this version please use the download link that was sent to you in the initial email and download the version manually. If you can't find the download link click here to download the app.

If you have any issue don't hesitate to contact us directly and we'll fix it as soon as possible.

If you want to suggest a new feature or vote on existing features for the next update you can do that in the public roadmap.

Sizzy 0.20 πŸŽ‰

Sizzy 0.20 is here! πŸŽ‰πŸŽ‰πŸŽ‰ Let's dig in 😍

πŸŒ“οΈ Simulate Light/Dark mode

The prefers-color-scheme CSS media feature is used to detect if the user has requested the system to use a light or a dark color theme. With Sizzy, now it is possible to simulate the prefers-color-scheme property.

This feature affects the content inside of the devices. If the website you're working on has support for prefers-color-scheme it should switch to the chosen color scheme, accordingly.

You can switch between three color schemes:

  • Light color scheme
  • Dark color scheme
  • System's color scheme (whatever you have chosen in your OS settings)


You can also simulate the color scheme per device, by going through the device menu β†’ choose a color scheme. In this case, only the chosen device will override the color scheme. This way you can work on the light and dark mode of your app at the same time 😍


In order to reset the color scheme of all the devices, you just need to click on the "Reset Color Scheme" button in the left sidebar. Then the devices that have manually been set to a certain color scheme, will reset to the default color scheme mode, set from the left sidebar.


πŸ”Ž Zoom page in Full Mode & Reference Browser

We made zooming in and out possible in Sizzy's Full Mode and in the Reference Browser. By pressing on the Cmd or Ctrl in combination with + or - you can control the zoom level.


You always reset your zoom back to the default one, by pressing on the Cmd or Ctrl + 0.

Please note that this zoom is different than the zoom in the Default mode. In Default mode, the zoom increases and decreases the size of the devices. While the fullscreen zoom makes the content inside the Full mode and Reference Browser tabs look bigger or smaller.

⚑️ DevTools extensions on Windows

DevTools extensions are finally enabled on Windows! You can go to Settings -> Dev Tools and enable the extensions for React, Vue, Angular, or whatever else you need πŸŽ‰ πŸ₯³


🐞 Additional Fixes

  • Fix navigation crash on some websites
  • Fix "Screenshot of all devices" button that used to freeze the app
  • Bug fix for screenshots getting stuck on specific websites after a refresh

If you have any issue don't hesitate to contact us directly and we'll fix it as soon as possible. If you want to suggest a new feature or vote on existing features for the next update you can do that in the public roadmap.
