GitHub Copilot CLI brings Copilot's coding agent to the terminal: it reads your repository, edits files, runs commands, and completes tasks from natural-language prompts. It supports custom model providers through plain environment variables, and with a custom provider configured it runs without a Copilot plan or even a GitHub login. Point it at Opper's OpenAI-compatible gateway and it works with any of 700+ models, with fallbacks and a choice of region on one key.
GitHub Copilot CLIoninPaste this into your coding agent (Claude Code, Cursor, Codex, and more) and it will set up and build with Opper for you.
