These years focused on refining the user interface and expanding processor support. IDA transitioned from a DOS-based tool to a native Windows application.
Hex-Rays currently offers several versions of IDA tailored to different user needs, ranging from free educational tools to high-end enterprise solutions.
Historically, IDA went through a major architectural shift. Early versions (pre-6.0) were primarily 32-bit applications. As malware and legitimate software moved to 64-bit architectures, IDA had to evolve.
In its early years, IDA was sold for as little as $30, a stark contrast to the premium tool it is today.
Version 6.0 introduced a cross-platform Qt-based GUI, standardising the experience across Windows, Linux, and macOS.
