The boring half of every product, already written

Sessions, password resets, social login, subscription state, proration, dunning, customer portals. None of it is hard exactly — it's just weeks of work that never becomes a feature anyone asks for.

Start with attributes, escalate to the API

Add a script tag and data attributes and you have signup, login, and gated elements. When you need real logic, the JavaScript SDK and REST API expose members, plans, and custom fields, and webhooks push events into whatever you already run.

Stripe, without the webhook rota

Subscriptions, one-time payments, trials, coupons, proration, and the customer portal run through your own Stripe account. Memberstack keeps member access in sync with subscription state, so nobody has to own the failed-payment edge cases.

Framework-agnostic by design

It's a script, not a framework. eFiling.us runs it across a Webflow front end and a Chrome extension with server-side token validation. Extropy Academy runs it on plain HTML, CSS, and JavaScript. Nothing about your stack has to change.

Why developers pick Memberstack over rolling their own

Firebase, Auth0, and a hand-rolled Stripe integration will all get you a login. The difference shows up in what you're still maintaining a year later.

Developer FAQs

Firebase and Auth0 solve identity; you still build subscription logic and keep it in sync with access control. Memberstack owns both, so a lapsed Stripe subscription revokes access without you writing a webhook handler. Alura looked at Firebase first and described Memberstack as "100x easier" to set up. If you need enterprise identity federation beyond OIDC SSO, a dedicated identity provider is still the right call.

Stop writing auth. Start shipping features.
