Continue is pretty cool. I can ask coding questions (I use Gemma for chat), it has code completion (does not work for me with deepseek-coder-v2 nor codegemma, but starcoder-v2 works). It can refactor code and has simple RAG with "@codebase" reference, as seen on the screenshot.

All is local on my laptop, no data is sent to third parties, running ollama.
