The Brief

What Memberstack Auth does

Memberstack is a membership and authentication platform that adds user logins, Stripe payments and gated content to websites built with Webflow, WordPress, custom code or AI site builders. It is aimed at agencies, freelancers, developers, founders, marketers and educators. Authentication options include email and password, one-time login codes and social logins. Payments cover Stripe subscriptions, one-time charges, free trials and tiered plans. Owners can gate pages, sections or elements by plan or login, store custom member fields, send email campaigns to members and build custom data tables. Memberstack is free until a site launches. Paid plans run from $29 to $499 a month, with transaction fees falling from 4% to zero, plus Stripe fees.
