What Vivisect is

Vivisect is a free, open-source static analysis platform for examining binaries, with the related Vdb tool providing cross-platform debugging. It supports pure Python static and dynamic analysis, including built-in static and symbolic analysis, and offers hybrid analysis. Work can run through an extensible UI, scripts, an API, or headless command-line processing. Bulk analysis can save a workspace as a .viv file, while distributed analysis is available through cobra. Vivisect supports Linux, macOS, Windows, self-hosted use, and architectures including i386, amd64, ARMv7, Thumb16, Thumb, AArch64, MSP430, and H8. Firmware analysis is listed, but a decompiler is not. Python 3.6 and later are supported through pip; the gui extra adds PyQt5 dependencies. Workspaces can be shared between instances or served over a network, and Vdb can attach to processes or launch and attach to them.

Who it suits

Vivisect suits developers, reverse engineers, and analysts who need scriptable binary analysis, debugging, firmware analysis, or headless processing. It is also relevant to users wanting self-hosted or distributed workspace collaboration.

What it does well

Free Apache-2.0 open-source software
Static, dynamic, symbolic, and hybrid analysis
Headless bulk analysis from command line
Multiple architecture targets listed
Workspace sharing and distributed analysis

What to know first

No decompiler listed
GUI requires the PyQt5 extra
Current package requires Python 3.6 or newer
