Prova vs Guardrails AI
Guardrails catches what you told it to catch. Prova catches what you didn't know to look for.
Try Prova freeGuardrails AI is a rule-based output validator. You define validators; it checks whether outputs match them. Prova is a formal reasoning verifier. You provide no rules; it determines whether the argument structure is logically valid.

| Detects unsupported leaps | Yes | No |
| Issues signed certificates | Yes | No |
| Immutable audit log | Yes | No |
| Content moderation | No | Yes |
| Schema validation | No | Yes |
| Math foundation | H1(K;Z) = 0 | heuristic |
| Self-hosted deployment | Yes | Yes |
Where Prova is different
No rules to write or maintain
Guardrails requires you to author, test, and version validators for every failure mode you anticipate. Prova's formal verification requires nothing from you except the reasoning text.
Catches unknown failure modes
Rules only catch what you expected. Prova's argument graph analysis finds structural failures you would never have thought to write a rule for.
Certificates vs logs
Prova issues signed, immutable certificates with precise failure citations. Guardrails produces pass/fail logs. For regulated industries, only one of these satisfies an auditor.
Use Guardrails for content policy enforcement and schema validation. Use Prova when you need to know whether the reasoning itself is logically sound.
