Opper AI
Opper AI is a European AI gateway and control plane designed for developers building autonomous AI agents. It provides a single OpenAI-compatible API key to access over 300 AI models across 30+ inference providers with native EU data residency and GDPR compliance. The platform features zero prompt storage by default, per-team spend caps, fallback routing, and PII masking, allowing teams to switch underlying LLMs instantly without updating data processing agreements.
What it does
• Exposes a drop-in OpenAI-compatible API endpoint that unifies access to 300+ AI models across 30+ providers. • Enforces strict EU data residency and GDPR compliance hosted on AWS Stockholm without storing prompt text by default. • Acts as a single AI sub-processor to allow hot-swapping underlying LLMs without updating DPA legal contracts. • Provides an agent control plane with tracing, automatic fallback chains, PII masking, and per-team budget limits.
Why it works
Passes through provider token pricing without markup, taking only a transparent 3% to 5.5% platform fee on credit top-ups. Eliminates procurement friction by serving as a single legal EU sub-processor across dozens of LLM inference vendors. Drop-in compatibility with OpenAI, Anthropic, and Google SDKs enables instant deployment via base URL updates. Hosted in AWS Stockholm to guarantee GDPR compliance and EU data sovereignty for enterprise client requirements.

Founder story
Opper AI was founded in Stockholm, Sweden, by Felix Wunderlich, André J, and Farouq Aldori. Building AI applications, they realized developers faced constant procurement and DPA contract changes whenever a new top-performing LLM was released. They created Opper AI as a European AI gateway that unifies 300+ models under a single DPA while keeping data resident in the EU.
