IDA Pro vs Vivisect

IDA Pro is a disassembler, decompiler and debugger for analyzing processors, file formats and software. It supports disassembly for more than 60 processor families, and its debugger works with multiple targets, including remote applications. The bundled gooMBA plug-in uses algebraic and program-synthesis techniques, heuristics and an SMT solver to simplify obfuscated binaries. Automation options include the IDA C++ SDK, IDAPython API, IDAT command-line functions and the idalib headless library. Teams can work with GitHub, GitLab, Bitbucket, Gitea or another Git remote, with Git LFS support for large IDB files. Private Lumina is a self-hosted add-on that restricts a knowledge base to authorized users; it exchanges function hashes and metadata rather than entire byte patterns. IDA Pro runs on Linux, macOS and Windows. The IDA Pro Essential plan costs $1,099 a year, with a one-year minimum commitment and no monthly payments. Hex-Rays states that there is no free trial and points users to IDA Free for checking basic capabilities.

Vivisect is a free, Apache-2.0 static analysis platform for binaries, with the related Vdb tool providing cross-platform debugging. Its pure-Python tools perform static and dynamic analysis, including built-in static and symbolic analysis, in a hybrid workflow. Analysis can run through an extensible UI, scripts, an API, or headlessly; command-line bulk processing can save a .viv workspace. Distributed analysis is available through cobra. Vivisect runs on Linux, macOS, and Windows, and lists i386, amd64, ARMv7, Thumb16, Thumb, AArch64, MSP430, and H8 architectures. Python 3.6 and newer are supported and installation is available through pip. The gui extra adds PyQt5 dependencies. Workspaces can be shared between instances or served over a network or localhost, with connected updates propagating as events arrive. Vdb can attach by process ID or command-line substring, or start and attach to a process.
