Sylphx vs Supabase
Database + auth vs. complete SaaS infrastructure
Supabase is a popular open-source Firebase alternative built on Postgres. It's great for database and auth. But when you need billing, AI, analytics, email campaigns, or background jobs, you're reaching for additional vendors. Sylphx covers the full SaaS stack from one SDK.

Key differences
SaaS services beyond database and auth
Supabase's core strength is Postgres + Auth + Storage. Sylphx includes all of that plus billing (Stripe-compatible), AI gateway (200+ models), analytics, email, feature flags, background jobs, monitoring, referrals, and more — 18 services in total.
TypeScript SDK design
Supabase has good TypeScript support, but each feature (auth, database, realtime, storage) has its own API surface. Sylphx's SDK is designed as a unified interface — one client, consistent patterns across every service.
Pricing model
Supabase uses project-based pricing with a free tier limited to 2 projects. Additional projects, row-level security advanced features, and higher connection limits require paid plans. Sylphx is fully usage-based with a generous free tier across all services.
Open source vs. managed
Supabase is fully open source and self-hostable, which is a genuine advantage for teams with compliance needs. Sylphx also offers a self-host option with the same managed experience, so you can get the benefits of both.
