What it is

Aider runs in your terminal, reads code, and proposes edits as git diffs. Works against any OpenAI-compatible endpoint, including Ollama and llama.cpp running locally. The killer feature is the surgical edit format: aider gets the model to emit small, targeted diffs that almost always apply cleanly, even with mid-tier local models like Qwen 2.5 Coder 32B.

✓ Strengths

  • +Terminal-native — no IDE lock-in
  • +Git-aware: every edit is a commit you can revert
  • +Excellent edit-format that minimizes apply failures

△ Caveats

  • Steep learning curve vs IDE-integrated agents
  • Needs 32B-class model for production-quality edits
