Project development started in the middle of 2013 because of the lack of cross-platform open source utilities for tinkering with UEFI images. UEFITool is a cross-platform open source application written in C++/Qt, that parses UEFI-compatible firmware image into a tree structure, verifies image's integrity and provides a GUI to manipulate image's elements.

More information on UEFI is available on UEFI Forum official site and in Wikipedia. In 2015 there are numerous systems using UEFI-compatible firmware including PCs, Macs, Tablets and Smartphones on x86, x86-64 and ARM architectures. The first EFI-compatible x86 firmwares were used on Apple Macintosh systems in 2006 and PC motherboard vendors started putting UEFI-compatible firmwares on their boards in 2011. Unified Extensible Firmware Interface or UEFI is a post-BIOS firmware specification originally written by Intel for Itanium architecture and than adapted for X86 systems. UEFITool is a viewer and editor of firmware images conforming to UEFI Platform Interface (PI) Specifications.
