Aider
Aider · Developer & Infrastructure
Open-source AI pair-programming CLI. Aider runs in your terminal, connects to any LLM via API, edits your codebase, and commits changes to git. Completely free (open source, MIT license) — users pay only for underlying LLM API tokens. Popular with terminal-heavy developers who prefer Unix workflows over GUI editors.
In other words, Aider is worth it for developers who live in the terminal and want an AI pair programmer without a GUI editor. The git-native workflow (every AI edit becomes a commit) is genuinely differentiated — you get an audit trail for free. Costs are pure LLM API usage, typically $10-50/mo for active users on Claude Sonnet or GPT-5. Downside: no team features, no autocomplete (chat-only), and requires you to already have LLM API accounts set up.
