How this works
How is the LaunchDarkly estimate calculated?
LaunchDarkly Foundation is billed roughly $12 per server-side service connection per month plus $10 per 1,000 client-side monthly active users. The calculator multiplies your inputs by those published rates. Enterprise pricing is negotiated and usually higher.
How is the Flagsmith estimate calculated?
Flagsmith hosted plans meter API requests and cap seats per tier (Free 50k/1 seat, Start-Up $45/1M/3 seats, Scale-Up $300/5M/5 seats then ~$50/seat). The calculator picks the cheapest tier that fits your requests and seats, then adds seat overage.
How is the Unleash estimate calculated?
Unleash Cloud Pro is $75 per seat per month, so the estimate is simply $75 × your seat count. Self-hosting the open-source edition has no licence fee but real infrastructure cost, which this tool does not estimate.
Why is ShipSilently flat?
ShipSilently Pro is $49/mo with unlimited seats and 10M evaluations included (overage $0.01 per 10k). There is no per-seat, per-connection or per-MAU meter, so the bar does not move as you grow.
Are these exact quotes?
No, they are estimates from each vendor's published list pricing, verified June 2026 and re-checked quarterly. Real contracts (especially Enterprise) vary. Always confirm with the vendor. Sources are linked below.
