Flagsmith vs Convert Experiences
Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.
Entry price
From $40 per month (Start-Up, billed yearly; $45 monthly)
Free tierFrom $299 per month (Growth, paid annually, 100k tested users; $399 monthly)
Trial onlyWhat drives the bill
The metric that actually scales your invoice.
Free covers 50k requests a month and one seat; Start-Up raises that to 1M requests and 3 seats, Scale-Up is $250/month yearly. Considerably cheaper than LaunchDarkly, and self-hosting removes usage pricing entirely.
Priced only on tested traffic — unlimited experiments, domains and users at every tier. Growth is $299/month paid annually ($399 monthly) for 100k tested users; Pro starts around $420/month annually.
