Pay for customers who show up.
The metric is monthly active customers: a customer with at least one event in the calendar month, in production. Sandbox is never billed. Seats are unlimited. Every tier gets the full engine, every action type, webhooks, simulation and AI drafting under a fair-use quota.
| Tier | Monthly | Included active customers | Beyond included | Also | |
|---|---|---|---|---|---|
| Developer | $0 | 1,000 production active customers, unlimited sandbox | hard cap | 1 project, community support | Start free |
| Pay as you go | $0 base | 1,000 free | $0.02 per active customer | card on file, docs and community support | Start free |
| Starter | $99 / mo | 5,000 active customers | $0.02 each | 3 projects | Start free |
| Growth | $499 / mo | 50,000 active customers | $0.008 each | 90-day audit retention, roles, priority support | Talk to us |
| Scale | $1,500 / mo | 250,000 active customers | $0.005 each | 99.9% SLA, SSO when built | Talk to us |
| Enterprise | custom | negotiated | negotiated | dedicated instance, data residency, DPA, 99.99% | Talk to us |
Events are not the meter. A fair-use allowance of 100 events per active customer per month, with a cheap overage as an abuse guard, not a revenue line.
Pay as you go has no cliff. 2,500 active customers cost $30; 5,000 cost $80. Starter makes sense when you need more projects, not to save money.
Prices are versions. Plans live in the database as versioned data. Your organization keeps its version until you move.
