Aider

## When to choose Aider Use Aider when your workflow is already terminal-centric and you want an agent that respects git hygiene. Aider is the strongest open-source option for engineers who review diffs before shipping. ## What it does well - **Git-native workflow.** Every edit becomes a commit or a proposed diff. You can review, revert, or amend exactly like any other contribution. This makes Aider unusually safe for production codebases. - **Architect / editor split.** Ask a reasoning model like Claude Opus to design a change, then have a fast coding model like Qwen Coder implement it. This two-model pattern improves both design quality and token cost. - **Voice mode.** Aider is one of the few agents that lets you dictate code changes from the terminal without reaching for the keyboard. - **Broad provider support.** Works with OpenAI, Anthropic, Google, OpenRouter, local Ollama, and many others. ## Honest limitations - **Terminal-only.** If you want a visual IDE integration, Aider is not it. It lives in your shell. - **Requires repo discipline.** Aider assumes you have a clean git state and meaningful context. In a messy repo, it can propose changes against the wrong baseline. - **No built-in browser or GUI testing.** It edits and runs shell commands. Verification beyond unit tests is up to you. ## Best fit Senior engineers, DevOps, and backend developers who want AI assistance without leaving the terminal or polluting their git history.
