Welcome to the CyberKit wiki!

What is CyberKit?

As you may already know, iOS provides a system installation of WebKit in the operating system. However, an updated browser is pretty important, and due to Apple's OS optimizations on iOS, we've acted as if it's not possible to upgrade WebKit without updating iOS.

CyberKit is a drop-in replacement for WebKit, thanks to Apple open sourcing WebKit for all these years. Simply put, the project backports newer WebKit to make it function on older OS versions.

How is CyberKit distributed?

CyberKit is distributed as two test browsers, rather than attempting to replace the system implementation of WebKit.

• MobileMiniBrowser is basically the most barebones browser you can imagine, with virtually zero features beyond CyberKit itself.
• Fennec is a compiled version of the iOS Mozilla Firefox browser, altered to use CyberKit instead of WebKit.

I'm installing a version before 0.0.9 alpha. Why doesn't it work?

Versions of CyberKit before 0.0.9 alpha additionally have to do legacy jetsam configuration before installing.

There's a separate wiki page on this here. Feel free to use the automatic method.

What iOS versions are supported?

Definitions:

Symbol	Definition
🥇	Beta support (relatively inconsequential bugs may exist, but it can be used as a primary browser)
🥈	Alpha support (somewhat significant bugs impact usability, but it can visit sites)
🥉	Pre-alpha support (significant bugs prevent visiting most sites, but it has been observed to display a specific webpage)
🔺	Not supported (installation always succeeds, but CyberKit always fails)
❓	Untested (behavior unknown, CyberKit is presumed to fail)
🔻	Not supported (installation exists, but never succeeds)
❌	No attempt to support (no installation exists)
+	Rootful
-	Rootless

This table only applies if you are jailbroken or have TrollStore.

Please note that iOS and iPadOS are considered equivalent in CyberKit.

Some values may be extrapolated from reports or presumed, rather than directly observed. Please report if this table is erroneous in any way.
