Winsock Packet Editor ProĪrunprasad Rajkumar is working on it in June I found a StackOverflow question of WinCairo performance.
Cygwin has epiphany and midori packages, but very old. WinCairo port is a redistributable upstream Windows port. However, the required library WebKitSupportLibrary. You can compile out both 32bit and 64bit AppleWin port by yourself. The latest 64bit built binary can be downloaded from Buildbot.
AppleWin port is supporting both 32bit and 64bit versions because iTunes for Windows is supporting them. The browser becomes unresponsive while running JavaScript benchmarks. And, WebKit thread is not separated from UI thread. It uses the same components with Mac port, i. AppleWin port is a upstream port which is used for iTunes for Windows. Sometimes I see someone asking about WebKit for Windows.
