A like-for-like, spec-level comparison. Both entries are verified against their docs and repo.

Aider

AI pair programming in your terminal, git-native.

  • + Every change is a git commit for trivial rollback
  • + BYOK with any model, including local
  • − Terminal-only, no IDE UI
  • − Steep for non-CLI users

Pi

A minimal, extensible terminal coding-agent harness.

  • + Tiny, opinionated core that stays out of your workflow
  • + Extensible via typed TypeScript skills and shareable packages
  • − Skips built-in sub-agents and plan mode by design
  • − Younger extension ecosystem
