Opper offers access to over 300 models through a single API key, with hosting options in the EU for better compliance. It is fully compatible with existing OpenAI, Anthropic, and Google SDKs, so switching only requires updating a base URL. The service stands out because many of its providers run inference within Europe, it uses a single EU sub-processor for all models, and it does not store prompts by default. You also get a powerful control plane for routing, PII masking, spend caps, and audit trails. It is built for agents, allowing you to integrate it into tools like Cursor with just one line of code.
