Memberstack alternatives: 3 free & open-source picks
Curated, verified, and actually free. No trials, no crippled tiers. Star counts and last-activity dates checked by hand, not scraped and forgotten.
All four nouns are present, but the website becomes a Ghost publication rather than keeping its current stack.
licenseMIT
runsyour machine or their cloud
installRun Ghost-CLI on supported Ubuntu/MySQL hosting; the official Docker path is available but still documented as preview
dataPosts, members and settings in MySQL; images under Ghost's content directory by default or through a configured storage adapter
the catch vs MemberstackGhost cannot attach auth, member records and billing to an arbitrary existing stack; the site becomes a Ghost publication.
setupSelf-hosting needs a server, domain, DNS, TLS and transactional/newsletter mail, plus Ghost upgrades

Authentication, member records, recurring billing and gated content inside WordPress; arbitrary-site embedding is gone.
licenseGPL-2.0
runsyour server
installInstall the WordPress plugin, create membership levels/pages, then connect a supported payment gateway
dataWordPress users/usermeta plus PMPro membership, order and discount tables; card credentials remain with the payment gateway
the catch vs MemberstackPaid Memberships Pro works inside WordPress rather than embedding cleanly into arbitrary Webflow, React or custom sites.
setupA maintained WordPress/HTTPS site, payment gateway, webhooks and reliable email delivery are prerequisites

Hosted users, subscriptions and gated content for a small membership site; you move the site into its ecosystem.
licenseproprietary, free
runstheir cloud
installHosted signup
dataContacts, funnels, course/community content, orders, emails and uploaded files in systeme.io's vendor-managed cloud; the underlying storage format is not published
the catch vs Memberstacksysteme.io cannot drop authentication and billing into an arbitrary existing site the way Memberstack can; the site moves into systeme.io.
setupSelling requires connecting a payment gateway; the free plan is capped at 2,000 contacts, three funnels, one course, one community and one custom domain

MedusaIt handles commerce primitives, not drop-in site authentication, member data and content gating.
SupabaseAuth and data are there, but this is a developer backend, not a membership product a non-builder installs.

Memberstack: Creators pay to outsource payments, tax complexity, disputes, deliverability, moderation, and the trust needed to convert strangers. If none of that applies to you, any pick above saves $348 a year.
Is there a free alternative to Memberstack?
Yes: Ghost, Paid Memberships Pro, systeme.io. Every tool on this page is either open source or genuinely free to use long-term: no trials, no crippled tiers.
Should I just build my own Memberstack?
Our verdict is PARCIAL. The visible website memberships loop is buildable, but a credible replacement needs more than the first screen. Memberstack earns its keep through payments, network, compliance, so expect a weekend or multi-day build and a narrower personal scope. If you'd rather build, the exact one-shot prompt is free at puedovibecodearlo.app/memberstack.
