Our call

If you want autonomy, choose Claude Code. If you want code quality, choose Aider. The 6–1 direct split is not a landslide; it is a difference in working style.

Choose Claude Code if you…

  • Need the broadest evidence base
  • Value autonomy and speed most
  • Can accept usage-limit and reliability friction

Choose Aider if you…

  • Work in a very large codebase
  • Want explicit file control
  • Prefer local-first data handling

Why developers switched

The same decision, from both sides.

Paraphrased from comments where a developer named a preference or described a switch. Each links to the original.

Picked Claude Code 6 developers

I needed something to help me stay off the computer (sites and applications) at certain times of the day with enforcement and in a way that's hard to remove. I had some ideas but was able to systematize all that into a proper program that I use daily. It's been very effective and it's much better (for me) than any of the commercial solutions that I've found for Linux. About 40% of the program was done using Aider (before I picked up Claude Code). The rest is using CC. https://github.com/nibrahim/glocker
