The past month or so I've been largely using Claude Code (similar to aider, which I haven't used in 6+ months, and OpenAI Codex I gather), from the CLI, for the "vibe coding" portion, and then hop into vim for regular coding when I need to "take the stick". I don't have any AI tools integrated into vim (though I do have LSP, etc). This method has been pretty effective, though I would like to have some AI built into the editor as well, my experiences with Cursor and Zed haven't been as rewarding as I'd like so I've iterated towards my current Claude Code. My first serious project, a fastapi-based replacement for an ancient Ruby on Rails project is just in "dev test" mode and going out to production probably in 2.5 weeks.
