Opper AI

Target users

Opper AI is built for developers and engineering teams who need a single, compliant gateway to multiple AI models. It suits startups and enterprises that want to avoid vendor lock-in, maintain GDPR compliance, and easily switch between frontier models without rewriting integration code. The platform also appeals to teams using coding agents (like Claude Code or Codex) who want to control which model those agents run on.

How to use Opper AI?

1. Create an account: Sign up at opper.ai for yourself or a company, and invite team members anytime.
2. Add credits: Top up credits to use with any model or provider, or bring your own provider keys.
3. Make your first call: Use the OpenAI SDK with the Opper compat endpoint. For example:

ts
   import OpenAI from "openai";
   const client = new OpenAI({
     apiKey: process.env.OPPER_API_KEY,
     baseURL: "https://api.opper.ai/v3/compat",
   });
   const response = await client.chat.completions.create({
     model: "anthropic/claude-sonnet-4-5",
     messages: [{ role: "user", content: "Hello!" }],
   });
   

1. Agent-assisted setup: Alternatively, paste the provided curl command into a coding agent like Claude Code, Cursor, or Codex to automate the setup.

Pricing and free trial

The website states "pay-as-you-go" pricing and mentions topping up credits, but does not list specific prices or a free trial. No pricing tiers or free trial details are provided in the crawled text.

Effect review

Opper AI delivers exactly what it promises: a straightforward, compliant gateway to hundreds of models with minimal setup friction. The drop-in compatibility with the OpenAI SDK is a genuine time-saver—you don't need to learn a new client library or rewrite existing code. The agent-assisted setup feature is clever, letting tools like Claude Code configure the gateway automatically from a single command. For teams operating under GDPR or other EU data regulations, the EU-hosted option and built-in governance controls (observability, routing, PII masking, audit trails) are practical differentiators. The platform is already trusted by a large developer community, which suggests reliability at scale. If you need multi-model access without compliance headaches, Opper AI is a strong, no-nonsense choice.
