CSS bugs are hard to deal with. We get it. Sizzy comes with a bunch of new ways to investigate and play around with the styles of your webpage, saving you a lot of time and frustration.

Every project requires a slightly different development setup. We understand the pain of context-switching when you are working on multiple projects. Sizzy makes this switch as seamless and intuitive as possible. All your data and configuration is saved with your project so you can pick up where you left off.
