The kings of SSB

Coherence X4 and Unite 4 are the industry leader in SSB (site-specific-browser) tools. Together, they enable experiences that will completely change your workflow, and the way you'll use your Mac forever.

There are some key differences, so to help you decide which is right for you, we've detailed the major distinctions here. One way or another, Coherence or Unite will be the best SSB tool for you on the market.

Engine

The fundamental difference between Coherence and Unite is the backend engine used to power your apps.

 

Coherence is chromium-based, and can use a variety of browsers, including Chrome, Brave, Edge, Opera and Chrome Canary. Because Coherence uses cross-platform browsers by third-party vendors, it is more powerful internally, but limited in additional OS-level functions. 

 

Unite is built on WebKit 2, the same engine that powers Safari, and uses the custom, BZG-built Unite browser to power your apps. While not supporting all of the extensions and functions of Chrome, it supports a number of OS-level functions that make your apps more 'app-like' on macOS.

Average app size

As a result of the dramatically different backends, the average app size varies significantly between Coherence and Unite apps.

Typically, you can expect each Coherence app to be between 30mb-90mb, though it can vary wildly depending on what extensions you add to your app.

Unite apps are all generally around 14mb, though they can fluctuate in border-line cases.

Extensions

If you're looking to use web extensions like Grammarly, Honey, or 1Password, you'll need to use Coherence, as they are exclusive to chromium-based apps and not available in Unite.

If you're looking to customize styles, blocks ads, or generally enhance the appearance of your apps, Unite can likely do it using it's vast customization features.

In-app customization

Because Unite apps use the BZG-built Unite browser, they exclusively feature deep customization options both natively and on site. This includes the ability to change window styles, create status bar apps, use user scripts and styles, block ads, and much more.

Sharing & distributing apps
