I was using aider quite a lot from ~ 7 months ago to ~ 3 months ago. I had to stop because they refuse to implement MCPs and Claude/Codex style agentic workflow just yields better results.

Still loyal to aider. It just fits my style better, as a very fine tool. I have my workflow and scripts around it, switch freely between gpt-5/sonnet (a bit of gemini-2.5-pro too) and enjoying life.

I wish it was maintained by a larger team though. It has a single maintainer and they seem to be backlogged or working on other stuff. If there was an aider fork that ran forward with capabilities I'd happily switch.

That said, I haven't tried Claude Code firsthand, only saw friends using it. I'm not comfortable letting agents loose on my production codebase.

I still use aider, because often I know better what to do.
