Guardrails AI

Guardrails AI builds software for validating and testing AI applications. Its open-source Guardrails framework lets developers check LLM interactions for personal information leaks, hallucinations, jailbreaks and application-specific policy violations. It supports chatbots, retrieval-augmented generation pipelines and agent workflows, with deployment in a customer's cloud or on-premises. Snowglobe complements runtime validation with simulation testing: teams can exercise conversational agents against varied user personas and scenarios before production, then export those scenarios into evaluation datasets.

The company is led by co-founder and CEO Shreya Rajpal. Snowglobe's engineering approach combines persona modeling with stateful, multi-turn conversations grounded in an agent's particular use case. Its scenarios include ordinary user behavior rather than assuming every interaction is adversarial. At its 2025 introduction, the company reported that customers were already generating tens of thousands of simulated conversations before production.

Alongside its open-source tools, Guardrails AI sells access to its platform through commercial subscriptions. Its validator distribution and deployment model is changing: the company set August 25, 2026 as the cutoff for Guardrails Hub installation, its private validator registry and hosted remote inference. Validators move to public PyPI packages; affected model-based validators must run locally or use customers' own inference endpoints.
