Vaara

Open-source evidence layer gating AI agent tool calls with a hash-chained, offline-verifiable audit record.

PlatformWebfreeglobal

Vaara is an open-source "Accountable Autonomy" evidence layer that gates every AI agent tool call against policy and writes a hash-chained record an auditor can verify offline, without trusting the operator. It runs entirely in the user's own environment, with no SaaS or telemetry, and can bind evidence to TPM 2.0 or SEV-SNP hardware attestation. Aimed at organizations under AI governance regulation such as the EU AI Act.
