What is Grepture?
Grepture is an AI gateway tool that lets developers trace, evaluate, and protect every LLM call their application makes. Built as a unified gateway with a drop-in, zero-dependency TypeScript SDK, it works with OpenAI, Anthropic, Gemini, and other providers. On the hot path it acts as a proxy that redacts personally identifiable information and blocks threats using 80+ detection rules, while giving full observability through detailed request logs and waterfall traces. Built-in evals use LLM-as-judge scoring so teams can measure output quality, and cost tracking surfaces token spend across multiple model providers. A zero-data mode processes requests without storing content, which is useful for sensitive workloads, and the infrastructure is EU-hosted in Frankfurt and Nuremberg. Grepture is fully open-source and self-hostable, with a free tier covering up to 1,000 requests per month and no credit card required. It is aimed at engineering teams who need observability, security, and cost control over their LLM traffic in one place.
