| Purpose | NeMo Guardrails is an open-source Python package for adding programmable guardrails to LLM-based applications. | Prompt Firewall decides whether text is allowed, flagged, or blocked before it reaches an LLM. |
NeMo Guardrails suits developers and teams building LLM applications that need configurable policy enforcement and safety checks. It is relevant to projects using Python, supported frameworks, or a self-managed deployment.
Prompt Firewall may suit AI application teams preparing LLM features for production and developers building agents. Developers can use the npm package or CLI in applications and CI, while the browser demonstration processes text client-side.
