For C++, we do support Bazel via compile_commands.json; we have customers who have used it successfully. Depending on the editor you're using, you probably need to get Bazel to generate a compile_commands.json anyways.

So core code navigation functionality ought to work. There are some issues with different language features (macros, newer C++17 and C++20 features), as well as robustness (crashes on indexing certain code) but we're looking into bringing C++ support up to par with other languages.
