In-Depth Comparison

Aider Overview

Aider is an open-source AI pair programming tool that works in your terminal. It can edit multiple files, understand your git history, create commits, and works with virtually any LLM via API. Known for its practical approach to real-world coding tasks and excellent benchmark scores.

Roo Code Overview

Roo Code began as a fork of Cline and grew into its own power-user favourite. Its signature feature is modes: switchable personas like Architect (plan), Code (build), and Debug (fix), plus fully custom modes with their own prompts and tool permissions. It supports auto-approval settings for hands-off runs, MCP servers, and any OpenAI-compatible provider. The trade-off for all that configurability is a steeper setup than Cline — and, like every BYO-key agent, your API bill scales with how hard you run it.
