ConfigCat's free tier offers 10 feature flags per product, 2 environments, 2 products, 4 targeting rules per flag, and 5 million requests per month. ConfigCat's paid plans expand these limits significantly: Pro at $110/month raises flags to 100 and requests to 25 million, while Smart at $325/month removes all caps on flags, environments, products, targeting rules, and webhooks. G2 reviewers note the free plan is useful for evaluation but restrictive for production use, with one reviewer citing the 100-email targeting cap as a limitation. ConfigCat's Enterprise and Dedicated tiers add up to 1 billion requests and on-premise hosting options respectively.
