Overview
Sourcetrail is a free, open-source, cross-platform source explorer that helps you get productive on unfamiliar code. It works offline and supports C, C++ and Java. It runs on Linux, Windows and macOS, and an SDK called SourcetrailDB lets you write extensions for other languages. The original authors archived the project at the end of 2021, and this fork aims to keep it buildable.
