A worked example
Straightforward billing.
One number, per device. Here is what a real app pays on FortressFlag - and how far that lands below the largest competitor's list price for the same setup.
A real app
What a real app pays
100,000 monthly devices · 10 backend instances across 2 environments · 5 people editing flags
FortressFlag
per month, estimated for this setup
~40% cheaper than the largest competitor, for the same setup.
Every extra replica, worker or environment adds nothing. A sixth editor adds nothing. Poll as often as your app needs - a device is counted once a month, not once per request.
This is an estimate for the setup shown, at list price. Your invoice is metered on the monthly-active devices your apps actually reach, so the final amount will vary with your usage; the rate itself - $6 per 1,000 devices after the first 1,000 - does not. The percentage is against the largest feature-flag vendor's published list price for the same setup, yearly billing, as read on 2026-09-11.
