ConfigCat vs Flagsmith

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 $110 per month (Pro)

Free tier

From $40 per month (Start-Up, billed yearly; $45 monthly)

Free tier

What drives the bill

The metric that actually scales your invoice.

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 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.

Free tier

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

Free cloud tier with a monthly request allowance; open-source self-hosting is unlimited.
