Aider
Open-source AI pair programming in your terminal (Apache 2.0).
AI Agents
What you get
Terminal coding agent that maps your codebase, auto-commits to git, and works with cloud or local LLMs.
How to get it
Install aider from aider.chat.
What it requires
An LLM: a cloud model API key or a local model.
The catch
No hosted plan; you pay your own model API costs unless you run a local model.
