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.
OpenCodeoninPaste this into your coding agent (Claude Code, Cursor, Codex, and more) and it will set up and build with Opper for you.
