OpenCode is SST's open-source coding agent for the terminal. It runs as a fast, keyboard-driven TUI, works across your whole codebase, and was designed from the start to be provider-agnostic rather than tied to a single model. On Opper you get a single key to 700+ models behind it, transparent pass-through pricing, and a choice of EU or US hosting.
Paste this into your coding agent (Claude Code, Cursor, Codex, and more) and it will set up and build with Opper for you.
Claude Sonnet 5 runs on the routes below. Route only to EU providers when your data has to stay in Europe.
