Sylphx vs Firebase
Google's BaaS vs. TypeScript-first SaaS infrastructure
Firebase pioneered the Backend-as-a-Service model with Firestore, Auth, and Realtime Database. But Firebase locks you into Google Cloud, uses NoSQL by default (no SQL joins), and bills unpredictably at scale. Sylphx delivers a modern alternative: managed Postgres, TypeScript SDK, predictable usage-based pricing, and 18 additional SaaS services.

Key differences
SQL (Postgres) vs. NoSQL (Firestore)
Firebase's primary database is Firestore — a NoSQL document store. Great for simple data models, but painful for relational data, complex queries, and data migrations. Sylphx uses managed Postgres — standard SQL, migrations, joins, and full ACID compliance.
TypeScript-first SDK
Firebase's SDK is JavaScript-first with TypeScript types added on. Sylphx is built TypeScript-first from the ground up — 100% type safety across every service, with generated types from your schema.
Predictable pricing
Firebase's Spark (free) tier has hard quotas, and Blaze (pay-as-you-go) bills can surprise teams at scale — Firestore reads cost money, Cloud Functions can spike. Sylphx uses transparent usage-based pricing with spending caps and real-time alerts.
Vendor lock-in
Firebase ties you deeply to Google Cloud — Firestore's query model, Cloud Functions, and GCP IAM. Migrating away requires rewriting data models. Sylphx uses standard Postgres, open formats, and offers a self-host option so you're never locked in.
SaaS-specific services
Firebase covers the basics well: auth, database, storage, hosting, push notifications. Sylphx adds the rest: billing, feature flags, analytics, email campaigns, referrals, engagement mechanics, consent management — everything a SaaS product needs.
