Prova vs LiteLLM Proxy
LiteLLM unifies the API. Prova adds the audit, the enforcement library, the boundary manifest, and revocable agent capabilities.
BOOK A CALLLiteLLM Proxy is the open-source AI gateway most teams reach for first: unified API across 100+ providers, per-key budgets, fallbacks. Prova adds the parts a regulated team needs on top: tamper-evident Ed25519 receipts, 19 built-in policies, runtime autonomy boundaries, revocable per-agent capabilities, per-agent attribution, and EU AI Act / FDA / SEC / HIPAA evidence export.

|---|---|---|
| Unified API across LLM providers | No | Yes |
| Per-key budgets that block | Yes | Yes |
| Per-agent attribution (multi-agent systems) | Yes | No |
| Runtime autonomy boundaries (allowed_tools, max_steps) | Yes | No |
| Fail-closed guarantee mode at the gateway | Yes | No |
| Per-agent IAM (revocable capabilities) | Yes | No |
| Ed25519-signed receipts, verifiable offline | Yes | No |
| 19 built-in policies + coordination-loop detector | Yes | No |
| EU AI Act / FDA / SEC / HIPAA evidence export | Yes | No |
| Open source core | No | Yes |
Where Prova is different
Built for the audit ask, not just the API ask
LiteLLM solves "how do I call any LLM with one client and a budget cap." Prova solves "how do I produce an Ed25519-signed audit trail an EU AI Act auditor can verify offline." Different problem, complementary tools.
19 policies + revocable agent capabilities
LiteLLM has budget caps. Prova has PHI / PII / secrets / prompt-injection / data-residency / runaway-step / dangerous-tool / monthly-budget / boundary-violation policies enforced at the gateway, plus per-agent capabilities you can grant just-in-time and revoke in real time.
Pair them
LiteLLM as the upstream proxy that unifies the provider API. Prova as the control plane that adds enforcement, signing, and audit. Most regulated teams ship both.
Use LiteLLM as the provider-unification layer. Add Prova on top for enforcement, signing, revocable capabilities, and the regulatory audit trail. Two tools that ship together in a serious deployment.
