Best Memberstack Alternatives in 2026

Memberstack adds user auth and gated content to Webflow and other sites, but teams look for alternatives when they need more control over their authentication layer, a fully custom auth system, or a backend that is not tied to a frontend platform. We have integrated auth solutions across 50+ client projects and know exactly where each tool excels and where it breaks down. This comparison covers the best Memberstack alternatives by use case, pricing, and technical fit.

01

Supabase Auth

Best full-featured free authentication

  • ✓ Free
  • ✓ PostgreSQL-native
  • ✓ RLS integration
  • ✓ OAuth + email + magic link
  • ✗ Requires WeWeb or custom frontend

Supabase Auth is built directly into the Supabase platform, meaning the same service that hosts your database also handles authentication. Row-Level Security policies can reference the authenticated user ID, making it trivial to restrict any database row to its owner without writing custom middleware. Free for up to 50,000 monthly active users.

  • ✗ Expensive at scale
  • ✗ complex setup

Auth0 is the most feature-complete auth platform, supporting custom SAML SSO, advanced MFA, compliance certifications (SOC 2, ISO 27001), and extensive audit logging.

03

WeWeb

Best when building the full app in WeWeb

  • ✓ Built-in auth connected to Supabase
  • ✗ Tied to the WeWeb platform

Why teams replace Memberstack

Memberstack is a convenient auth layer for Webflow sites, but teams outgrow it when: (1) They need Row-Level Security, restricting database rows per user requires a backend-level auth system, not a frontend plugin. (2) They move beyond Webflow, Memberstack is primarily built for Webflow. Other frontends need different auth solutions. (3) They need SSO or enterprise auth, Memberstack covers basics, but Auth0 and Supabase handle enterprise SSO more robustly. For production SaaS apps, Supabase Auth is the standard choice.

Our recommendation

Supabase Auth, For no-code apps built on WeWeb + Supabase, Supabase Auth is free, powerful, and natively integrated.

Frequently asked questions

Can Supabase Auth replace Memberstack?

Yes, for most use cases. Supabase Auth handles email/password, magic links, OAuth, and integrates natively with Row-Level Security.

Is Memberstack worth the cost?

Memberstack is worth it if you're building on Webflow. For WeWeb or custom apps, Supabase Auth is free and more powerful.

What is the best Memberstack alternative for WeWeb?

Supabase Auth with WeWeb's native connector. WeWeb has a built-in Supabase auth integration that handles login, signup, magic links, and OAuth. Row-Level Security in Supabase restricts data per user at the database level.

Is Auth0 overkill for a small SaaS?

For an early-stage SaaS, yes. Supabase Auth is free up to 50,000 MAU and covers all common use cases. Auth0 is better for enterprise requirements (custom SAML SSO, compliance certifications). Start with Supabase, migrate to Auth0 if you need enterprise features.

Does App Studio use Memberstack?

No. App Studio uses Supabase Auth for all production SaaS apps. Supabase Auth is free at startup scale, handles all OAuth providers, and integrates natively with WeWeb and FlutterFlow. Memberstack is a good Webflow-specific solution but not part of our stack.
