Checked October 2026.

## What is Kaitai Struct?

Kaitai Struct is a declarative language designed for describing binary data structures found in files or memory.

The tool allows users to define the layout and format of binary data structures once using its specialized language syntax. These descriptions can then be compiled into source code for multiple programming languages, automatically generating parsers that provide structured access to the binary data.

The generated parsers offer a comprehensible API that simplifies the process of reading and interpreting binary file formats and network stream packet formats. This approach eliminates the need to manually write parsing code for each target programming language.

Kaitai Struct supports various binary data structures including file formats, network protocols, and memory layouts. The tool's compiler can generate parsers for different programming languages, enabling cross-platform compatibility and consistent data access patterns across different development environments.
