Structured Log Viewer

The viewer opens MSBuild binary log files (*.binlog) and presents the recorded build events in an interactive interface. It allows users to explore the exact sequence of tasks, targets, and inputs, replay a log to reconstruct text output at any verbosity, and search using a defined syntax. Features include sensitive‑data redaction, command‑line help for the /bl switch, and documentation for programmatic access and LLM integration.

It is aimed at developers and build engineers who need to diagnose, analyze, or audit MSBuild processes, especially when using Visual Studio or the dotnet build command with the –bl flag. The tool works on macOS and can be installed via standard package managers.

Distinctive aspects are the binary format’s completeness, higher verbosity than diagnostic text logs, reduced build overhead, and smaller file size. The viewer also provides guidance on recording logs with older MSBuild versions and cautions about design‑time build limitations.
