Websites and hosting decision
Memberstack
A single engineer can build a useful auth+Stripe gating MVP, but reproducing Memberstack's compliance, integrations, and production-scale infrastructure is expensive and time-consuming, so keeping the SaaS is reasonable for production needs.

Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- Provide member signup/login, attach members to paid plans via Stripe, and gate content based on member plans.
What it still won’t have
- SOC 2 / compliance certifications and audit reports
- Decades of production-hardening and scale (fraud monitoring, uptime SLAs)
- Built-in branded email campaigns and native email sending platform
- Existing third-party integrations and plugins ecosystem
- Operational burden of handling payment disputes and edge-case billing scenarios
What remains hard
- Compliance and regulation
SOC 2 TYPE 1 CERTIFIED
- Infrastructure at scale
$200M+ processed
- Infrastructure at scale
10M+ member accounts managed

Paying is—cheaper in year one.
On cash alone, building overtakes the subscription at 1 seat.

Runnable build prompt
Build a minimal membership backend using Node.js (Express), Postgres (managed like Supabase or RDS), and Stripe for payments. Core features in scope: secure email/password auth (signup, login, reset, email verification), Stripe subscription and webhook handling (create customer, subscribe to plans, handle invoice.payment_succeeded and invoice.payment_failed), member profile storage with custom fields in Postgres, a small admin dashboard (list/search/export members, change/cancel subscriptions), and a client-side script to gate pages/elements and expose current member state to the frontend. Out of scope: full email campaign builder, enterprise SSO, SOC 2 audit, and multi-tenant scaling. Require input validation, webhook signature verification, error handling, unit tests for API handlers, and basic E2E tests for signup→payment→gating flow. Deploy to a single managed server (or Vercel) and use managed Postgres and Stripe; include a README with setup, environment variables, and data migration/export instructions.
