AI pair programmer in your terminal

⭐ 48k+ stars 📜 Apache-2.0 🏷️ ai-tools

Overview

AI pair programmer in your terminal

✓ Git-native AI coding — automatically creates descriptive git commits for every change made
✓ Works across entire codebases up to ~100K lines with intelligent file selection
✓ Average coding session costs ~$0.05-$0.50 with Claude 3.5 Sonnet; predictable API spend

✗ Terminal-only — no GUI for users who prefer visual code editors like VS Code
✗ Large monorepos (>500K lines) require --map-tokens tuning to avoid context overflow
✗ Best results require GPT-4o or Claude Sonnet; quality degrades noticeably with smaller models
