It can run as an MCP server, so you can use it for free with Claude Desktop, and it can still fully understand a code base, even a very large one. No API key or subscription required!
We did this by using a language server instead of RAG to analyze code.
Can also run it on Gemini, but you'll need an API key for that. With a new google cloud account you'll get 300$ as a gift that you can use on API credits. Local models work as well.
Check it out, super easy to run, GPL license.
