The standard is free and open. The managed platform that turns your agents' actions into auditor-ready, independently verifiable evidence is what we sell — to the teams that have to answer to a regulator.
Banks, fintechs and trading desks deploying agents that move money or make customer-facing decisions, and must reconstruct exactly what happened on demand. Receipts your supervisor can verify offline, without trusting your logs.
Teams where an agent's action carries clinical or actuarial consequence and a paper trail is non-negotiable. Tamper-evident provenance for every step, exportable as evidence for an audit or a dispute.
Organisations building toward EU AI Act Article 12 logging obligations, NIST AI RMF, or an ISO/IEC 42001 AI Management System — who need the evidence pack to be ready, not reconstructed the week before the audit.
The standard, free forever.
AGPL-3.0 & CC-BY-4.0

We're working hands-on with a small first cohort of regulated AI teams to shape the Cloud platform around a real audit. You bring an agent deployment with a compliance obligation; we bring the team that built the standard.
The same reason teams run managed Postgres or pay for a hosted Sigstore: the standard is free, but running the ledger, proving policies, retaining evidence, and producing an auditor-ready pack at scale is operational work you'd rather not own. Cloud does it for you.
The engine is AGPL-3.0 (with a commercial licence for proprietary embedding), the receipt spec is CC-BY-4.0, and the reference implementations are MIT. See GOVERNANCE.md.
A guardrail decides; a log records what it claims happened. Raucle emits a signed, content-addressed receipt that a third party — a regulator, a counterparty — can verify offline, and the policy behind each decision is machine-checked to be sound. Evidence, not assertion.
Yes. Receipts you produce self-hosted are the same format Cloud ingests and verifies — nothing to migrate. Start free, move to Cloud when the audit burden is real.
Cloud runs in-region with configurable retention; Enterprise supports on-prem / VPC and data-residency requirements. Verification never requires us to hold your signing keys.
Early access is open now via the design-partner programme. Register interest and we'll bring you in as cohorts open.
