Claude Code is Anthropic's agentic coding tool for the terminal. It reads your whole repository, plans and applies changes across files, runs commands and tests, and iterates on failures from natural-language prompts — all without leaving the shell, on macOS, Linux, and Windows. On Opper it runs on any of 700+ models, not just Claude: pin one with a single --model flag, switch mid-task without losing context, and choose EU or US hosting on one key.
Claude CodeoninPaste this into your coding agent (Claude Code, Cursor, Codex, and more) and it will set up and build with Opper for you.
