Aider is the original open-source AI pair programming tool for the terminal. It maps your whole git repository, edits files across the codebase, and commits as it goes, so every change stays under version control. It talks to any OpenAI-compatible endpoint, so set its base URL to Opper's gateway and you can run it on any of 700+ models with one key and a choice of region.
AideroninPaste this into your coding agent (Claude Code, Cursor, Codex, and more) and it will set up and build with Opper for you.
