Aider vs Cline
Updated Jul 17, 2026 · pricing verified for both tools
Aider wins for terminal and git-centric workflows; Cline wins for VS Code users who want a GUI agent with Plan and Act modes. Both are free, open-source, and bring-your-own-model, so you pay only provider API costs — which can top $100/month on frontier models. Aider runs in the terminal with automatic git commits and a public model leaderboard; Cline runs in VS Code with multi-file diffs, checkpoints, MCP tools, and paid team tiers. Both do their best work driven by top Claude models.
