Pros & Cons
Aider
- Every AI-made change is a real, revertible git commit
- Works across multiple files in a codebase, not just single-file edits
- Open-source and not locked to a single AI model provider
- Requires comfort with the command line rather than a graphical IDE experience
- No built-in chat sidebar or visual diff review the way some IDE-integrated tools offer
- Users need to bring their own API key for the underlying AI model
Bolt.new
- Runs entirely in the browser with real live preview, no local environment setup needed
- Bolt Cloud extends generated apps with real backend infrastructure
- Supports switching between multiple coding agents within the same project
- Token consumption is tied to full project syncing, so large projects or error loops burn through allotments quickly
- Generated code still benefits from engineering review before production use
- Fast-moving category — worth comparing directly against current alternatives before committing
