Membership Platform for Webflow, WordPress & Any Site

The verdict: can you vibe code Memberstack?
Build your own authentication and subscription wrapper in Next.js rather than paying for this, unless you need to inject it into external no-code site builders.
If you are building a native full-stack SaaS app, assembling Next.js, better-auth, Postgres, and Stripe with an AI agent is completely viable in a couple of weeks. However, replicating Memberstack's exact value proposition—injecting secure authentication and gating snippets via script tags into arbitrary third-party Webflow or WordPress sites while managing multi-tenant Stripe subscriptions—introduces heavy cross-origin token and CORS engineering debt.
Estimated effort: 2-3 weeks part-time
What you can't replicate
- SOC 2 Type 1 compliance certification
- Native zero-code integration plugins across Webflow and WordPress ecosystems
- Years of edge-case hardening around Stripe webhooks and multi-currency billing

Build guide
01Project Scaffolding & Database Schema
Initialize a Next.js project with TypeScript, Tailwind CSS, and connect Neon Postgres using Drizzle ORM.
Create a new Next.js project with TypeScript and Tailwind CSS. Set up Drizzle ORM connected to Neon Postgres. Define database schemas for users, memberships, plans, data_tables, and webhook_logs with strict foreign key relations and indexes. Write a migration script and verify local database connection.02Authentication Integration
Configure better-auth for secure email/password and social login flows stored in the database.
Install and configure better-auth in the Next.js app to handle email/password sign-up, login, and Google OAuth. Implement secure session cookies, token refresh cycles, and password reset flows. Ensure auth endpoints properly sync user records to the Neon users table upon registration.03Stripe Billing & Webhook Handlers
Implement Stripe Checkout sessions and robust webhook endpoints to manage subscriptions and plan states.
Build Stripe integration endpoints using the Stripe SDK. Create API routes to generate Checkout Sessions for recurring membership plans. Implement a secure webhook receiver route (/api/webhooks/stripe) that handles customer.subscription.created, customer.subscription.updated, and customer.subscription.deleted events, safely updating user plan tiers and statuses in the database with signature verification.04Client-Side SDK & Content Gating
Build an embeddable JavaScript SDK and React package that reads membership state and toggles element visibility.
Develop a client-side JavaScript SDK bundle that can be injected via script tag. The SDK should check active session cookies, fetch user permissions from the backend, and evaluate data attributes (e.g., data-ms-content='protected') to show or hide DOM elements dynamically. Also provide React wrapper components for gating content cleanly.05Admin Dashboard & Member Data Tables
Create an administrative dashboard interface to manage members, assign custom fields, and configure data tables.
Build a responsive admin dashboard in Next.js allowing site owners to view list of members, search by email, manually assign plans, update custom fields, and manage custom data tables (dynamic CRUD schemas). Protect all admin routes with role-based access control checking admin status.06Email Campaigns & Notifications
Integrate Resend for transactional emails and automated member communication broadcasts.
Integrate the Resend API to handle transactional emails (welcome emails, password resets, payment failures) and build an email campaign composer interface in the admin dashboard. Allow filtering recipients by plan or custom attributes, previewing templates with merge tags, and dispatching batch emails securely via background tasks.
