People with large codebases, what agentic tools do you use?

Hey guys, I’ve been using Cursor for a while, but it seems to really struggle now that our codebase has grown quite large (>30k LOC).

I’m curious what tools you guys are using for large codebases. Is there anything out there that can operate agentically but is built for large codebases?

Would love to hear your thoughts or workarounds!
