GleeBug is an open-source debugging framework for Windows designed to streamline application analysis and debugger development. It provides developers with an accessible, transparent, and completely free programming toolkit without tracking or licensing restrictions.

Technical Overview of GleeBug

GleeBug operates as a low-level programmatic debugging library written in C and C++, interfacing directly with native Windows debugging APIs to monitor processes, handle exceptions, and intercept execution events. It functions as a source-available, portable developer library rather than a standard installer package, allowing developers to embed it directly into custom debugging tools. Being free and open-source software under the MIT license, it runs offline and remains completely telemetry-free.

Core Features of GleeBug

  • Native debugging core enables low-level process control, exception handling, and breakpoint management on Windows targets.
  • Portable developer framework compiles directly into target projects without requiring traditional system installation or registry modifications.
  • Permissive MIT licensing grants complete freedom for code integration, inspection, and modification.
  • Ad-free architecture delivers a clean, lightweight environment with zero background telemetry.

System Compatibility
