> **1. ConfigCat** - my default recommendation for agencies. It's the only one whose pricing model actually matches how agencies work: flat tiers with **unlimited seats** on every plan including free, and quotas measured in "products" (Free = 2 products/10 flags, Pro = $110/mo for 3 products/100 flags, Smart = $325/mo for 10 products). You can hand a client's PM a login without it costing you $20/seat, and each client is a separate product with its own flags and environments. Also has an on-prem option if a client demands it.
