Snowglobe

You point Snowglobe at your LLM app, and it runs hundreds of simulated conversations with synthetic user personas in a matter of minutes.

What comes back is a set of judge-labeled results that show where your chatbot fails, including hallucination and toxicity, plus edge cases manual testing tends to miss.

Snowglobe is an AI simulation environment for testing LLM apps at scale, and the labeled datasets can also feed evaluation and fine-tuning work.

The self-service plan uses usage-based pricing, but it has limits: 250 scenarios per hour and three app connections.

Unlimited runs, guaranteed KPIs, expert reports, advanced analytics and stronger security sit in the Enterprise plan, which is priced on request.

That tier also covers VPC or on-premise deployment and HIPAA compliance, so regulated teams will land there.
