Convert Experiences vs ConfigCat

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 $299 per month (Growth, paid annually, 100k tested users; $399 monthly)

Trial only

From $110 per month (Pro)

Free tier

What drives the bill

The metric that actually scales your invoice.

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.

Plans run Free, Pro $110, Smart $325, Enterprise $900 and Dedicated $4,500 a month. Unlimited seats and unlimited flag reads on every plan, including free — unusual and genuinely valuable for wide access; paid tiers mainly raise flag, environment and product limits.

Free tier

15-day trial.

Free forever plan with a monthly config-request allowance and unlimited members.
