The honest brief
Aider
CLI-only and model-agnostic: auto-commits every AI edit as its own git commit, so changes are trivially revertable.
- Fully open-source, BYO-key
- Auto-commits each edit to git
- Works with any model incl. local
- Strong on its own Polyglot benchmark
- No editor lock-in — pure terminal
- No GUI — terminal comfort required
- You pay model API costs yourself
- Less hand-holding than IDE agents
- Setup/config heavier than hosted tools
Claude Code
Ships the same agent across CLI, IDE, desktop, and web — reads the spec, writes the diff, runs tests, opens the PR.
- Strong autonomous multi-step coding
- MCP and subagents support
- Runs on API key or Pro/Max plan
- Anthropic models only
- Token usage can get expensive
- Terminal-first learning curve
