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
Bolt.new
- +Full dev environment runs in the browser via WebContainers, with the AI controlling filesystem, terminal, and server
- +Generates true full-stack apps (not just UI) and can deploy via Bolt Cloud
- +No local setup; fast for prototyping and iterating by chatting
- -Token-based usage cost can rise quickly on complex or long-running builds
- -Output needs human review and iteration; it is not a hands-off autonomous engineer
