Sourcetrail developer here: Pretty solid. We use clang libTooling.

C# support would be cool too!

Yes, that's on the list as well.

How's the performance on a large codebase?

North of 500k lines, few thousand cpp/h files, 40+mb

We have been working on that for the past few month. Right now the performance is pretty good for C++ projects up to around 2 million lines of code. For C projects the performance is even better! If you want to test it, just download the pre-indexed clang project (900k loc) from our website (https://www.sourcetrail.com/downloads#extra). Indexing the project took 12 minutes on a 5 year old laptop.

Really great news! I think I'll give this a demo when I have some capacity.

Thanks

I tried it on a fairly big repo today (~500k loc) and once it was done with the initial processing performance was fine.

Compile commands ? Please Yes?

There is also a tool called Bear which will generate compile commands from Make-based builds, in case you were wondering. I've used it with some success.

Im well aware of bear. Works fine in some cases, not so well in others. Author is also doing scan-build replacement in python which imho is far superior to bear.

Yes, we support Compile Commands :)

What are compile commands?

A Compile Command is a JSON file entry that specifies what the C/C++ compiler should do when compiling a file. So it defines a file to compile and all the required flags (like include paths or preprocessor defines). These Compile Commands are used for all kind of Clang based tools.
