Opper AI

Opper provides a unified gateway to over 300 diverse models, all accessible via a single API key and hosted within the EU. It offers seamless integration with existing OpenAI, Anthropic, and Google SDKs, requiring only a base URL modification to switch providers. Key differentiators include: * EU-hosted inference for many models * Single EU sub-processor for all models * Prompt storage disabled by default * Control plane for routing and governance * Agent-native setup for quick deployment This platform emphasizes data privacy and operational control, with a significant portion of its providers running inference directly in Europe. The architecture is designed for compliance, utilizing one EU sub-processor across its entire model library and offering default settings that prevent prompt storage. Users can enhance control with a robust control plane that supports dynamic routing, PII masking, team-specific spend caps, and comprehensive audit trails, ensuring transparency and accountability. Opper is ideal for developers and organizations building sophisticated applications that require access to multiple advanced models while adhering to strict data residency and privacy regulations, particularly within the European Union. Its agent-native setup allows for rapid deployment—simply paste a line of code into agents like Claude Code or Cursor to configure Opper. The pricing model is transparent, with no markup on tokens and a minimal 3% fee on credit top-ups, making it a cost-effective choice for development and production environments.
