Memberstack

Memberstack is an authentication, billing and content protection layer for websites you host yourself. It is aimed at static site builders and front-end developers rather than at merchants who want a shop, and its most common use is adding paid memberships to a Webflow site, though it also works with WordPress, Framer, Ghost, React and Next.js applications, and plain HTML. The pitch is that you keep full control of design and content while Memberstack supplies member accounts, Stripe billing and access rules, which is a combination that otherwise takes weeks of custom development.

Member management starts with accounts. Memberstack provides hosted sign up and log in pages plus modal versions you can trigger from any element, so a design-tool site can present an authentication flow that matches its styling without writing a back end. Members get email verification, password reset and, depending on current configuration, social sign in options. Each member record carries custom fields and metadata that you define, which is how plans, roles, tiers or cohort data get attached to a person, and those fields can then be used as conditions in access rules. The dashboard lists members, supports search and filtering, and allows manual creation, editing and plan changes for support work.

Billing is built on Stripe. You connect a Stripe account, define plans as subscriptions or one-time payments, and attach those plans to sign up flows. Free plans are supported, which is how newsletters and gated-content sites operate without charging. Trial periods, coupons, plan upgrades and downgrades with proration, invoices and receipts are all handled inside Memberstack, and the payment record stays in Stripe so it reconciles with your payouts. Because the processor is Stripe, currency support, card brands and payment methods follow whatever your Stripe account supports rather than a Memberstack-specific list.

Content protection is where the architecture needs to be understood properly. Memberstack protects whole pages by URL rule, redirecting unauthorised visitors to a sign up page or a paywall. It also protects parts of a page, using elements marked up with Memberstack attributes so that a section, a download link or a video embed is removed from the page for visitors who lack the required plan or field value. On a static site this enforcement happens in the browser, after the HTML has been delivered. It reliably stops casual access and is fine for community pages, blog archives and marketing content, but it is not the same as server-side authorisation. Anything genuinely sensitive, such as unlisted video files, downloadable assets or API keys, should live behind an access-controlled origin, a signed URL or a server-rendered route rather than relying on client-side removal alone.

For developers, Memberstack publishes a client-side JavaScript SDK and a REST API, plus webhooks for events such as member created, plan changed and payment failed. That allows a custom front end to read the current member's plan and metadata, gate components conditionally, and drive back-end logic from membership events. The same API is what makes Memberstack usable in a Next.js or React application where the hosted modals would be inappropriate. Webhooks into a serverless function are the usual way to provision access to an external resource.

Integration coverage follows the no-code ecosystem. Webflow is the flagship case, with documented setup and marketplace distribution, and WordPress has a plugin. Framer, Ghost and static HTML sites are supported through the script snippet. Beyond that there are connections to email marketing tools and to automation platforms such as Zapier and Make, which is how most teams push member events into a CRM or an ESP. The integration list is shorter than a suite vendor's and changes between releases, so a specific connector should be confirmed before it becomes a requirement.

Memberstack differs from authentication providers such as Auth0, Clerk, Supabase Auth and Firebase Authentication in that those services stop at identity. They give you users and tokens, and you still build subscription state, plan logic, paywalls and a billing admin. Memberstack bundles those together with rules you can configure visually. It differs from Stripe Billing and Payment Links in the same way, since Stripe gives you the money movement but not gated pages or member metadata. It differs from Memberful, which hosts the member dashboard and leans on creator features such as private podcast feeds and Discord role syncing, by being closer to a developer tool for sites built in design software. It differs from WordPress membership plugins by living outside the CMS entirely, which avoids plugin conflicts and keeps card handling away from WordPress.

Pricing is structured as a free tier plus paid tiers that increase member limits, remove Memberstack branding from authentication screens, and reduce or remove the platform's revenue fee. Higher tiers add features such as custom domains for member pages, more granular access rules and larger member counts, and there is a custom or enterprise level for high-volume products. Annual billing is discounted against monthly. The exact tier names, member caps and prices have been revised more than once, so current figures should be taken from the Memberstack pricing page rather than from a secondary source.

The limitations are mostly about scope. There is no email marketing, no automation builder, no CRM, no course player, no community and no help desk, so Memberstack pairs with other tools rather than replacing them. There is no native page builder and no content storage, meaning the site itself stays in Webflow, WordPress or your own codebase. Member counts are capped per plan, which can force an upgrade faster than feature needs would. Support is documentation and chat based, and the depth of help varies with tier. Vendor dependence is real, because both your authentication and your subscription state sit in a third party, and while member data can be exported, recreating access rules and billing history elsewhere is manual work.

Memberstack fits designers and front-end developers who have built a marketing site, a resource library, a paid newsletter archive, a job board, a template marketplace or a lightweight SaaS front end in a tool such as Webflow or Next.js and need members, subscriptions and gating without writing a back end. It fits agencies that deliver member-enabled sites to clients and want a maintainable, configurable system. It does not fit businesses selling a structured video curriculum with assessments, communities that need forums and moderation, merchants with inventory and shipping, or products where protected content is high-value enough to require server-side enforcement and signed asset delivery.

Against the alternatives, the comparison is about where the work happens. Kajabi, Kartra and Podia own the whole experience and take your site with them. Memberful offers a similar hosted membership layer with stronger creator-specific features. Clerk and Auth0 offer more flexible identity at the cost of building billing and gating yourself. Memberstack's position is that it delivers the smallest amount of custom code for a membership site built in a design tool, and its weak point is that the same client-side model which makes it easy to deploy is not suitable for protecting genuinely sensitive assets. For marketing-tier gating it is a strong fit, and for anything beyond that it should be combined with a proper back end.
