Cline is an open-source autonomous coding agent for VS Code. It plans and applies multi-file changes, runs terminal commands, and works with any OpenAI-compatible provider, with its source on GitHub under Apache-2.0. Point its OpenAI-Compatible provider at Opper's base URL to run it on any of 700+ models, with fallbacks and a choice of region built in.
Paste this into your coding agent (Claude Code, Cursor, Codex, and more) and it will set up and build with Opper for you.
