Aider is written in Python (they have a great Discord community, btw). My experience matches yours: for Python, aider/Sonnet seems to do much better than for Javascript so far. I strongly recommend aider despite LLM limitations at the moment for anyone interested in this space.

It's also very sensitive, unsurprisingly, to development documentation that is moving quickly, e.g., most AI APIs right now. A lot of manual intervention is still required here because of out-of-date references to imports, etc.
