Aider

- +Model-agnostic with a repo map that scales to larger codebases
- -Terminal-only with no GUI or IDE-native experience for those who want one
- -Runs locally and edits real files, so a human must review every change
Factory
- +Model-agnostic with no lock-in (Claude, GPT, Gemini per task)
- +Strong enterprise deployment story: on-prem, air-gapped, SSO, SCIM, audit logging, zero-data-retention
- +Whole-repo primitives plus headless CI/CD automation via Droid Exec
- -Autonomy is marketing-forward but supervised in practice; you review every modification before it touches the codebase
- -Efficiency metrics are company-reported with no public methodology
