An EU-hosted AI gateway providing access to 700+ models from 50+ providers at provider rates with no token markup, offering pay-as-you-go pricing and features
What it is
Opper is an AI gateway built in Stockholm and hosted in the EU, providing developers and enterprises access to 700+ models from 50+ providers including Anthropic, OpenAI, Google, Meta, Mistral, and DeepSeek. The platform operates on a pay-as-you-go model with a 3% fee on Gateway and 5.5% with Control Plane, passing through provider rates with no token markup.
The gateway is OpenAI SDK compatible, supporting streaming, tool calling, and prompt caching. Developers can manage spend limits, set data retention policies (zero data retention by default), control model access through allowlists, and use routing and fallback options. The Control Plane adds advanced features including spend controls by project, role, and user, audit logging, SSO/SAML support, and custom hosting regions.
Opper also features research tools including the JevMan Pac-Man benchmark for decision models, the AI Roundtable for comparing model reasoning across 200+ models, and a model comparison directory. The platform offers a Management API for infrastructure-as-code integration and an MCP server for coding agent management.

Quick answers
- Do I need a credit card to start?
- No. Sign up gives you an API key immediately and free models work in the playground and API. Add a card later to use premium models with pay-as-you-go pricing and no minimum spend.
- How does pricing work?
- Token rates are the model providers' rates with no markup. Gateway charges a 3% fee when you buy credits; Control Plane charges 5.5% with additional per-check billing for LLM checks. No hidden charges or per-seat fees.
- What happens if a provider is down?
- You can pass a fallback model list per request. If the primary provider fails, the request is retried against the next model in the list, and you are only billed for the successful response.
- Are failed or fallback requests billed?
- No. You are only billed for the successful model response. If a request fails and is retried on a fallback model, only the successful attempt is charged.
- How do I migrate from OpenAI or Anthropic?
- Opper is fully OpenAI SDK compatible. Change your base URL and API key, and your existing code works as-is without requiring code changes.
