Free memory, forever. Pay for proof.
The memory engine runs locally, free forever — no account required. Pay when you want it synced across your fleet, then governed with attribution, policy, and an incident record you, your customer, and an auditor can independently inspect.
One Crux account. Paid tiers are per user; payments are processed by Paddle as merchant of record. Taxes are shown at checkout.
