Guardrails AI

Guardrails AI is an AI reliability platform that helps organizations build, govern, and scale production generative AI systems. It provides three core capabilities: synthetic data generation for training and fine-tuning models, dynamic evaluation dataset creation that targets risky outcomes and edge-case failure modes, and runtime guardrails that detect and block problematic outputs, policy violations, and hallucinations before they reach users. The platform includes the Guardrails Hub, a library of pluggable validators for common failure modes, and is used by enterprise customers including Masterclass and Changi Airport. Guardrails AI maintains an active open-source presence alongside its hosted offering, with a community on Discord, LinkedIn, and X/Twitter. Pricing follows a freemium structure, with self-serve access to the open-source library and Guardrails Hub, and paid or enterprise tiers for hosted runtime guardrails and support, available by signing up or getting started on the platform.
