Review & Alternatives

"Update your software faster."


WyBuild is a utility that gives developers the ability to create software update patches and distribute them to their user base quickly and easily. This open-source patch updater can help you expedite the process of updating your app regardless of the programming language it uses to operate.


Installing wyBuild is a simple process that even a non-developer could complete. However, basic programming knowledge is required to understand and utilize core functionality of the program. Supports all recent versions of Windows (both 32-bit and 64-bit).


As is to be expected with an advanced development tool of this caliber, the user interface is very diverse, and is therefore not recommended for novice users. In fact, you probably won't be able to appreciate the capabilities of this program unless you possess at least rudimentary programming knowledge. Even with the large number of advanced features, the GUI does a great job of keeping the main window free of clutter, with well-organized, self-explanatory button icons providing access to all of the important options and features.


  • Facilitates the process of auto updating .NET apps, and serves as a standalone updater for every other programming language, including C++, Java, Delphi, VB, C#and many more.

  • Drag-and-drop functionality makes it easy to import files into the wyBuild interface

  • Quickly becoming the industry standard for software patch creating, providing unparalleled version management benefits by scanning changes between software versions and generating Delta (VCDIFF) patches that can be distributed to your users

  • Utilize proprietary patching algorithms to drastically compress the size of patch updates, reducing patches with a file size of 50 MB to only about 1 MB

  • Gives you the ability to insert a wide range of script executions into your patch updates. Supports .BAT, .EXE,.CMD, and .MSI scripts

  • The first commercially available software to facilitate the process of distributing Automatic Updates

  • The automatic update feature uploads, extracts, and patches your users' software only a few short moments after you've released it

  • Includes a built-in translation editor that lets you create, customize, and send out multiple version translations within the updater

  • Built-in theme editor lets you customize the color, font, and layout of your patch updater module to match the existing theme of your company/brand/software. You can fine tune every aspect manually, or you can choose from a selection of predefined templates


  • With such a robust feature set, the learning curve involved with this program can be quite substantial, even for experienced developers. However, the degree of difficulty is a fair trade for the power that this software puts at your fingertips


Similar software patch generator/builder software available include Omaha (known as Google Update), PatchFactory, Microsoft ClickOnce, duP2, IncUpdate, AutoUpdate+, and RedShift Freestyle. Of these competitors, Patch Factory, ClickOnce, and duP2 are the most popular, providing similar features to wyBuild, but geared more towards installer creation.


Whether you're a game developer, consumer software developer, web designer, or IT specialist, wyBuild offers an excellent interface in which to create and distribute update patches that enhance your software's feature set and create higher user satisfaction rates.
