Featured Models

Intelligent LLM API Middleware

Frugger acts as a proxy layer between your applications and LLM APIs,
providing dynamic model routing, observability, and automated cost
reduction strategies.

Dynamic Model Routing

Intelligently selects the cheapest sufficient model per request based on prompt complexity analysis to maximize cost savings while maintaining quality.

Real-Time Cost Analytics

Comprehensive dashboard with usage metrics, cost tracking, and detailed reporting to identify optimization opportunities and monitor savings.

Intelligent Prompt Caching

Automatically caches repeated queries and similar prompts to reduce API costs and improve response times for common requests.

Multi-Provider Support

Full OpenAI API compatibility with support for both OpenAI and Anthropic models. Configure your provider keys (OpenAI for GPT models, Anthropic for Claude models) and use either seamlessly through the same endpoint.

Frequently Asked Questions

How does the "pay only when you save" model work?

We track your actual API costs and compare them to what you would have paid without Frugger. Our 30% fee is only applied to the money you actually save through our intelligent routing and caching. If we don't save you money, you don't pay us anything extra.

What happens after the first 100 free requests?

After your first 100 requests, the free tier switches to pass-through mode. Your requests will still work normally, but without our cost-saving optimizations like re-routing and prompt caching. You can upgrade to Pre-Paid at any time to restore full functionality.

How do you ensure I always save money?

Our fee structure guarantees you save money. Since we only charge 30% of your savings, you keep 70% of every dollar saved. For example, if we save you $100, you pay us $30 and keep $70 - resulting in a net positive outcome every time.
