Despite the project being archived and no longer maintained I continue to use it and recommend it. I use sourcetrail when diving into new codebases to help get a sense of the flow and organization of a program. I've mainly used it for C but also C++ a few times. If you have a compile_commands.json setting up sourcetrail is as simple as telling it where that file is located.

Though I do wonder if issues will start to crop up around new language features in C23 and beyond. We just moved our embedded C project to C23 and I haven't tried sourcetrail on it yet.

This is the ONLY source viewer that actually worked on Mozilla Firefox in enabling me to quickly bring myself up to speed and start working toward the JavaScript AST malware detector.

And became a JS JIT internal engine expert on multiple platforms with this.

Thank you so much for your Google summer internship on this!

Now if someone can remap the new compuler syntax with this fine piece of tool, the community will gain a bigger understanding of system design of large project ... in record time. (And no more VM for Analysis)
