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
Zed AI
- +Extremely fast GPU-accelerated Rust editor with AI built in
- +Open source with flexible model access (bring-your-own-key or hosted) plus MCP
- +Supervised agent with granular control: per-hunk diffs and tool-approval policies
- -Hosted models need a paid plan or your own keys; the free tier caps predictions and excludes hosted models
- -Younger and smaller ecosystem than VS Code
