KanColleViewer! is a Windows-only browser tool that provides a more informative interface for's Kantai Collection KanColle browser game.

About This Project

KanColleViewer! uses the Microsoft Internet Explorer components in WPF, WebBrowser, to display the game; Nekoxy is used to capture communications between the game's Flash client and the DMM servers. Therefore, from the game servers' point of view, using KCV is basically the same as using IE. Of course KanColleViewer! does not modify any game data nor implements any sort of macro cheating.

This project is a localisation of @Grabacr07's original application maintained by @Xiatian. The features added in this fork are based on previous work done by @Zharay, @silfumus and @southro_p; this particular fork, however, does not carry over any legacy code from Zharay's 2.x builds, much unlike my previous 3.x branch, and is a complete re-implementation.

Frequently Asked Questions

Please refer to the FAQ.

System Requirements

  • Windows 8 or later
  • Windows 7

The original developer, (@Grabacr07), uses Windows 8.1 Pro to build and test this application. The toast notification system from Windows 8 is not supported on Windows 7 (although you will still get the good old tray icon notifications). It's recommended to run KCV in Windows 8.

Windows 7 and 8.x require that you install .NET Framework 4.6. Windows 10 comes with it pre-installed.

KCV uses IE to display the game's web page, so it depends on IE settings. If you're experiencing issues accessing the game, please verify that Flash works in Internet Explorer. It's also recommended to install the latest version of Adobe Flash Player.

KCV does not perform Flash extraction and instead provides a viewport of sorts to display the game's 800x480 frame.
