What is JGuardrails and how do I add it to Spring Boot?

JGuardrails is a Java lib for LLM input/output safety. Add via JitPack: implementation("com.github.Ratila1:JGuardrails:v0.1.7"), then wrap your client in a pipeline.

Does JGuardrails prevent prompt injection in Java LLMs?

Yes, via pattern-based input rails that BLOCK known jailbreaks before your model call—works with any client.

Is JGuardrails production-ready for enterprise Java apps?

At v0.1.7, it's solid for core risks like PII, toxicity, JSON; scale with customs, but pair with monitoring.
