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.
