Commerce Simulator
See what it would have caught — before you turn anything on.
No one should enforce a policy they haven't watched work. The simulator runs your rules two ways: against synthetic attacks in the sandbox right now, and against your real traffic in read-only Shadow Mode — so the first thing enforcement touches is a number you've already seen.
What leaks without it
The blind rollout
Enforcing on day one means discovering edge cases on customers. Shadow Mode discovers them on a report instead.
The unpriced leak
You suspect promo stacking costs you money; the simulator shows which orders would have been held, and what they were worth.
The policy argument
Is a 15% floor too strict? Run it in shadow and settle the debate with your own traffic, not opinions.
Every outcome is one of three — and each leaves a signed record.
Allow
What would have passed — the quiet majority of your orders, untouched.
Would have held
The orders enforcement would have stopped, each with the rule and the dollars attached.
Review
Where your data couldn't answer — the gaps to fix before enforcement day.
Start in read-only Shadow Mode: see what would have been held on your real traffic before anything is enforced. How Shadow Mode works
