What MeterFlow, Autumn and Stripe Billing cost as your monthly billing volume grows, and what each one does — from their own pricing pages, with the day we read them.
The monthly platform fee at four levels of monthly billing volume — what your customers pay you. MeterFlow’s price follows your event volume instead, so it does not move with this table.
| Monthly billing volume | $5,000 | $8,000 | $10,000 | $20,000 |
|---|---|---|---|---|
| MeterFlow Flow | $29 | $29 | $29 | $29 |
| Autumn | $0 | $0 | $375 | $375 |
| Stripe Billing | $35 | $56 | $70 | $140 |

MeterFlow check() keeps answering when MeterFlow cannot be reached, with its last answer marked stale or the allow or deny you set per feature (Node SDK 0.10.0, Python SDK 0.5.0).Your bill follows how many usage events you send, not what your customers pay you: doubling your revenue does not double our fee.
MeterFlow never moves money. Your provider charges your customers; MeterFlow meters their usage, keeps their credits and answers whether they may go on. Paddle, Polar, Lemon Squeezy, Chargebee and Razorpay connect from the dashboard; anything else talks to the API.
An mf_test_ key reads and writes test data, an mf_live_ key live data — one project, two worlds that never mix, on every plan including the free one.
