Opper AI
One API key, 300+ models, hosted in the EU, built for agents
Overview
Opper AI positions itself as the European alternative to US-based AI gateways like OpenRouter, built around the idea that teams handling EU user data need a real answer on where inference happens and what happens to prompts afterward. The pitch is straightforward: one API key, no markup on token rates, and a small platform fee (3% on the base Gateway tier) instead of hidden margins baked into pricing.
It launched on Product Hunt on July 9, 2026 and has real signals of traction beyond the launch day, including a €3 million pre-seed round from investors connected to Lovable and a live G2 reviews page, which is more validation than most week-old tools have. That said, it's still a young infrastructure company asking teams to route production traffic through it, and infrastructure is exactly the kind of category where reliability only gets proven over months of uptime, not a launch week.
Key Features
One API for 300+ Models: Single key access across roughly 30+ providers, drop-in compatible with OpenAI, Anthropic, and Google SDKs.
EU Data Residency: About half of providers run inference in Europe, with one EU sub-processor covering every model and no prompts stored by default.
Agent-Native Setup: Configurable with a single line pasted into Claude Code or Cursor.
Control Plane Add-Ons: LLM-as-judge scoring, prompt optimization, PII masking, content filtering, and budget caps on the higher tier.
No Token Markup: Token rates match provider pricing directly, with fees charged separately as a percentage.
Pricing
Starting price

Gateway: 3% platform fee on credit top-ups. 300+ models, manual routing and fallbacks, BYOK support, community support.
Control Plane: 5.5% platform fee. Adds LLM-as-judge scoring, prompt optimization, PII masking, content filtering, budgets and limits, email and premium support.
Enterprise: Custom pricing. Configurable data retention, zero data retention option, audit logging, custom hosting regions, SSO/SAML, dedicated support.
Disclaimer: pricing may change, confirm on Opper's own pricing page before buying.
Pros
No Token Markup: You pay provider rates directly, with fees kept separate and transparent.
Real EU Hosting: Genuine data residency answer for teams with GDPR requirements, not just marketing language.
Early Funding and Reviews: €3M pre-seed and an active G2 page give it more third-party validation than most new launches.
Easy Migration: SDK-compatible design means switching from OpenAI or Anthropic clients takes minimal code changes.
Cons
Infrastructure Reliability Unproven: A gateway routing production traffic needs months of uptime history to trust fully, which it doesn't have yet.
Fees Scale With Usage: The 3% to 5.5% platform fee adds up at high volume compared to going direct to a provider.
Small Team: A recently launched pre-seed company, so support capacity is likely limited compared to established gateways.
No Flat Published Price: Percentage-based fees make it harder to estimate a fixed monthly cost upfront.
What Makes It Unique
EU-First Infrastructure: One of the few AI gateways built specifically around European data residency rather than treating it as an afterthought.
