I'm an engineer on the code intel team at Sourcegraph. You can try out compiler-accurate code navigation here https://sourcegraph.com/github.com/sourcegraph/sourcegraph@2... See "Go to definition" and "Find references".

The general idea is that you should be able to navigate your codebase online with Sourcegraph similar to how you would navigate the code with a local IDE (IntelliJ, VS Code). The benefits of Sourcegraph become more pronounced once the size of the codebase grows, especially across multiple repositories, and you're working with a large team of developers.
