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
Cursor
Pioneered agentic, multi-file editing in a familiar VS Code fork — frontier models bundled, no API key wrangling.
- Inherits the VS Code extension ecosystem
- Frontier models bundled in one plan
- Strong multi-file agent + tab completion
- BYO key supported
- Closed source (the editor itself)
- Heavier on usage limits at higher tiers
- No first-party Linux/mobile parity gaps
