Are there any member portal platforms that focus on building gated sites for communities and memberships?

Yes — there are several platforms specifically geared toward building gated member portals for communities, memberships, courses, and paid access areas. The best fit depends on whether you want more of a community-first product, a content/membership portal, or a fully custom portal.

Popular member portal / gated community platforms

• Mighty Networks – Strong for community + memberships + events, with built-in paid access and courses.
• Circle – Very popular for premium communities, discussion spaces, events, and member directories.
• Kajabi – Better if you want memberships plus courses, email marketing, and sales funnels.
• Podia – Simple all-in-one for memberships, digital products, and gated content.
• MemberSpace – Adds gated membership functionality to an existing website (especially useful with Webflow, Squarespace, Framer, etc.).
• Wild Apricot – Great for associations, clubs, and organizations that need membership management.
• GoSite / Memberful – More lightweight membership tools, often used with an existing website.
• Hivebrite – Strong for large communities, alumni networks, and professional associations.
• Ning – Community platform with social-network style member features.
• Discourse + membership tooling – Good if you want a forum-style gated community.
