The honest brief
Aider
CLI-only and model-agnostic: auto-commits every AI edit as its own git commit, so changes are trivially revertable.
- Fully open-source, BYO-key
- Auto-commits each edit to git
- Works with any model incl. local
- Strong on its own Polyglot benchmark
- No editor lock-in — pure terminal
- No GUI — terminal comfort required
- You pay model API costs yourself
- Less hand-holding than IDE agents
- Setup/config heavier than hosted tools
Cline
BYO-key VS Code agent that shows and asks approval for every edit and command — no markup, no lock-in.
- No vendor markup on token costs
- Approves every edit/command before running
- Bring any model (Claude, local, etc.)
- Plan/Act split for review before changes
- BYO-key means you pay provider token costs
- VS Code only, no standalone IDE
- Slower than Cursor on equivalent tasks
- No codebase indexing or background agents
