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
Cursor
- +Best-in-class Tab completion and tight, in-runtime AI integration that an extension-based tool can't fully match
- +Strong codebase-wide context, multi-file agent edits, Plan Mode, and parallel/cloud agents
- +Model flexibility plus fast in-house models (Composer) optimized for agentic coding
- -Pricing has been a sore point: a 2025 shift to credit metering caused surprise overage charges and backlash
- -Can hallucinate non-existent APIs and slow down on very large projects
