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
Claude Code
- +True terminal-native agent: reads, edits, runs, and commits across a whole codebase rather than autocompleting lines
- +Flexible autonomy, from per-action approval to auto mode to fully headless runs for CI
- +Deep ecosystem: MCP support, subagents, plugins, GitHub Actions, and IDE extensions, plus a public Agent SDK
- -API-token usage on heavy tasks can get expensive and hard to predict
- -Locked to Anthropic's own Claude models (no model choice)
