Editorial take
Why it stands out
Aider should be framed as a practical open-source coding assistant for serious local workflows, not as a lightweight novelty CLI.

Tool profile
Open-source terminal coding assistant that edits a local git repo directly and works with many frontier and local models.
Terminal coding assistant
Aider belongs in the catalog because it represents one of the clearest code-first alternatives to full AI IDE lock-in. The official site positions it as AI pair programming in the terminal, with direct edits to your local git repository instead of a separate hosted workspace or thin autocomplete layer. That makes it especially relevant for developers who want agentic code editing while keeping the rest of the workflow close to normal shell, git, and editor habits.
It also deserves inclusion because the economic story is refreshingly honest. Aider is presented on official surfaces as a free open-source coding assistant, and the real cost comes from whichever model provider you connect to, whether that is OpenAI, Anthropic, OpenRouter, Ollama, or another compatible backend. That is an important distinction for stack builders comparing product spend versus underlying inference spend.
