Aider
Pour
- +Best-in-class pair-programming flow in the terminal

- −Less polished autonomy than Devin or Replit Agent
GitHub Copilot
Pour
- +Biggest install base of any coding agent — every IDE, every language
- +Now ships an Agent mode that competes credibly with Cursor and Cline
- +IP indemnity tier is unique — meaningful for enterprise legal teams
Contre
