Pros & Cons
10 pros·6 cons across both
Supabase
Pros
- PostgreSQL engine with vector search and advanced SQL capabilities
- Native real-time subscriptions via PostgreSQL Realtime (publish-subscribe system)
- 15+ built-in authentication providers (OAuth, SAML, passwordless)
- Auto-generated REST and GraphQL APIs
- Mature ecosystem with 50,000+ active developers and strong community support
Cons
- Vendor lock-in with managed cloud hosting (requires migration effort to switch
- PostgreSQL-only, limiting flexibility for other database paradigms
- Higher managed hosting costs ($25-3,000/month depending on scale)
Appwrite
Pros
- 100% self-hosted with Docker—complete data control and no vendor lock-in
- Multi-database support roadmap (MongoDB, MariaDB coming)
- No recurring SaaS costs—infinite horizontal scaling at server cost only
- GDPR/HIPAA compliant self-hosting for regulated industries
- Active development with 25,000+ GitHub stars and growing enterprise adoption
Cons
- Requires DevOps expertise for self-hosting, monitoring, and database maintenance
- Real-time capabilities less mature than Supabase (Websocket-based, higher latency)
- Smaller ecosystem and fewer third-party integrations (10 authentication providers vs 15+)
Frequently Asked Questions
5 questions
Migration is possible but requires custom ETL work since the databases differ (PostgreSQL vs MongoDB). Supabase provides PostgreSQL export tools, while Appwrite requires importing into its MongoDB instance. The REST/GraphQL APIs differ slightly, so frontend code may need minor updates. Plan 2-4 weeks for enterprise-scale migrations including testing.
