Deviare is a professional hooking engine for instrumenting arbitrary Win32 functions, COM objects, and functions whose symbols are located in program databases (PDBs). It can intercept unmanaged code in 32-bit and 64-bit applications. It is implemented as a COM component, so it can be integrated with all the programming languages which support COM, such as C/C++, VB, C#, Delphi, and Python.
Several Fortune 500 companies are using Deviare technology for application virtualization, packaging, and troubleshooting, and for computer security. Computer science researchers are also using Deviare to conduct malware and reverse engineering studies. Our blog articles contain a vast quantity of code samples to get you started easily.
Deviare offers a unique programmer friendly API which resolves the complexities associated with binary instrumentation so that even software engineers without expertise in the field can use it. Deviare takes care of code injection, parameter marshalling, and inter-process communication. We created Deviare API in 2007 and continually improve it. Intercepting applications is a complex task. We test multiple application environments to ensure that the end user has a trouble-free experience. Deviare also has a focus on performance handling thousands of hooks with little footprint.
Code instrumentation is used in several other areas like: tracing and debugging, sandboxing and browser security, malware analysis, video conference recording, and gaming.

Deviare runtime runs on any computer with Microsoft Windows XP or later OS installed.
To compile Deviare and/or build samples you need:
- Visual Studio 2017.
- .NET Framework 4.
- Windows SDK 8 with all .NET Framework components installed.
NOTE: The database (.db) files you'll find in the BIN folder are NOT generated when building Deviare. Deviare needs these files to work. If you create new databases, don't forget to move them to the BIN folder. To create them you must first build the corresponding tools that are included in the solution. Refer to these instructions for further details.
Since Deviare depends directly on Deviare-InProc, it is
included as a submodule in this repository. To clone this repository do
git clone --recursive. If you already cloned without the
you can complete the repository initialization with
git submodule update --init --recursive.
We recommend always executing
git submodule update --init --recursive after pulling from this repository.
This ensures the Deviare-InProc submodule is up to date with the HEAD of the Deviare2 branch.
If you downloaded the zipped source package from Github instead, you need to satisfy this dependency manually.
To do so, place the contents of Deviare-InProc inside
To build Deviare you can either execute the build script (build.bat) in a VS2017 command prompt or open the solution and build it from within Visual Studio. When doing the latter, make sure to build for both x86 and x64 target platforms.
