Prova vs Arize AI
Arize observes your models and pipelines. Prova enforces the policy, signs each decision, and hands the regulator a verifiable trail.
BOOK A CALLArize AI is a broad ML and LLM observability platform: embedding drift, evals, and tracing (Phoenix). Prova is narrower and deeper on governance. It enforces policy and runtime boundaries at the gateway, signs every AI decision with Ed25519, controls what each agent may do, and produces the evidence export a regulated buyer needs.
| Feature | Prova | Arize AI |
|---|---|---|
| ML drift + embedding monitoring | No | Yes |
| LLM tracing + evals | Yes | Yes |
| Deterministic per-run verdict | Yes | No |
| Gateway enforcement (block before the call) | Yes | No |
| Ed25519-signed receipts, verifiable offline | Yes | No |
| Runtime autonomy boundaries | Yes | No |
| Per-agent IAM (revocable, just-in-time capabilities) | Yes | No |
| EU AI Act / FDA / SEC / HIPAA evidence export | Yes | No |
| Open-source tracing (Phoenix) | No | Yes |
| Self-hosted / air-gapped | Yes | Yes |
Where Prova is different
Governance depth over observability breadth
Arize is a horizontal observability platform. Prova does the governance layer in depth: enforce, sign, bound, and export, on top of the traces, rather than charting them.
Signed evidence, not metrics
Arize produces metrics and alerts. Prova produces Ed25519-signed receipts with offline verification, the evidentiary artifact for an audit.
Control what an agent may do
Prova's IAM for agents grants, expires, and revokes an agent's tools and data scopes in real time, enforced at the gateway. Observability cannot revoke a capability.
Use Arize AI for ML observability, drift, and tracing. Use Prova for enforcement, signed receipts, agent authorization, and the regulatory audit trail.
