Aider

- +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
Greptile
- +Reviews with whole-repository context via a code graph, not just the diff, and cites evidence for findings
- +Self-hostable on AWS with custom LLM providers, useful for security-conscious teams
- +Hands findings to coding agents and can write and run tests in a sandbox
- -Reviewer, not merger: it comments and suggests but a human still approves
- -Best language support is limited to a core set; broader languages are lower quality
