Droid is Factory's coding agent, running in the terminal, in IDEs, and in Factory's desktop app. It plans and executes real engineering tasks, and its bring-your-own-key support takes custom models on any OpenAI-compatible or Anthropic-compatible endpoint, on every plan. Add Opper as a custom model and you get one key to 700+ models, with usage billed straight through your Opper account.
DroidoninPaste this into your coding agent (Claude Code, Cursor, Codex, and more) and it will set up and build with Opper for you.
