The European AI gateway for agents. 700+ models from 50+ providers through one EU-hosted API. Drop-in OpenAI, Anthropic, and Google AI SDK compatible. GDPR-compliant. Opper is one API in front of every major AI model, hosted in the EU. Drop in your existing OpenAI, Anthropic, or Google AI SDK and keep your code, you get text, multimodal, and voice, plus observability, governance, and one sub-processor for every model. Not writing code? Point an app you already use, like Claude Code or Cursor, at Opper instead.
