Aider
- +Fully open source (Apache-2.0) and free; you only pay your chosen model provider
- +Git-native: every AI change is a reviewable, revertible commit
- +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
Cline
- +Open source (Apache-2.0) with no inference markup; bring your own model keys
- +Plan/Act mode plus per-step approval makes autonomy controllable
- +MCP support, browser control, and adoption reported at large enterprises
- -Auto-approve can run consequential commands; oversight still recommended
- -Costs scale with the model you bring; heavy agentic runs can get expensive
