Opper AI
The European AI gateway for agents.
Opper AI is an EU-hosted API gateway that provides access to more than 700 AI models from over 50 providers through a single endpoint. It is designed for teams that need to use multiple models without maintaining separate provider integrations, and it supports GDPR compliance, spend caps, model allowlists and zero data retention options.
The gateway is compatible with the OpenAI, Anthropic and Gemini SDKs, as well as coding agents and frameworks such as Claude Code, Cursor, Codex, LangChain, LlamaIndex and the Vercel AI SDK. It includes an LLM router with dynamic routing and fallback chains, automatic failover across providers, prompt caching, and a control plane for spend limits, data retention rules, model access policies, input/output checks and routing configuration. A Management API allows projects, keys, members and routes to be managed from code.
Opper is aimed at developers, teams and enterprises building AI applications. It offers a Gateway tier and an opt-in Control Plane tier, with Enterprise options for volume pricing, custom invoicing, SSO, audit logging and deployment in a customer's own cloud or datacentre. Pricing is pay-as-you-go with no minimum spend, based on provider token rates plus a fee on credit purchases. Free models are available without a credit card, and premium models require adding a card.
