Feature Comparison
Pros & Cons
Memberstack
Pros
- Deep Webflow integration with a native app inside the Webflow Designer
- Comprehensive auth options: email/password, social login, passwordless, and password reset
- Generous free tier with 100 members and unlimited free trial period
- Large library of free resources: 600+ Webflow components, 125+ Memberscripts, 100+ templates
- SOC2 Type II certified and GDPR compliant for security-conscious use cases
Cons
- Heavily tied to Webflow — not ideal if you use a different site builder or custom frontend
- Pricing page mentions transaction-based fees ($1-$4 per member tiers) that can add up at scale
- Relational database features are useful but limited compared to dedicated backend-as-a-service platforms
Supabase
Pros
- Full Postgres database that is 100% portable — no proprietary lock-in
- Comprehensive platform covering database, auth, storage, realtime, edge functions, and vectors in one service
- Generous free tier suitable for prototyping and small production apps
- Open-source with strong community and broad framework support (React, Next.js, Flutter, Vue, etc.)
- Built-in Row Level Security for fine-grained access control at the database level
Cons
- Requires understanding of SQL and Postgres concepts — not a true no-code solution
- Connection pooling and scaling require configuration knowledge (e.g., PgBouncer setup)
- Some advanced features and higher resource limits are only available on paid plans
- Self-hosting the open-source version requires significant DevOps expertise
Our Verdict
Both Memberstack and Supabase are excellent choices with similar feature sets. Your decision should depend on your specific needs, pricing, and whether you need self-hosting capabilities.
