What BaaS Actually Solves
Backend-as-a-Service platforms give you authentication, database, file storage, and real-time features without building them from scratch. For a one or two-person team, this cuts 3β4 months of development time.
Firebase
Google's BaaS β the most mature option.
Strengths: Real-time database (Firestore) is excellent for live updates. Authentication is battle-tested. Firebase Cloud Messaging for push notifications is best-in-class. Massive community and documentation.
Weaknesses: Pricing can escalate unpredictably β Firestore charges per read/write operation. Poorly optimized queries generate large bills. NoSQL structure is flexible but data modeling mistakes are painful to fix. Significant vendor lock-in.
Best for: Mobile apps with real-time requirements, teams already familiar with Firebase, apps needing excellent push notification support.
Indian concern: Unexpected Firebase bills are real. Budget monitoring is essential once you leave the free tier.
Supabase
Open-source Firebase alternative built on PostgreSQL.
Strengths: Real SQL with real relationships β familiar to most developers. Row-level security built-in. REST and GraphQL APIs auto-generated from your schema. Open source β self-hostable. Clean, developer-friendly dashboard.
Weaknesses: Less mature than Firebase. Some features still in beta. Smaller community (growing fast).
Best for: SaaS products with relational data (most B2B SaaS), teams wanting SQL without giving up BaaS convenience, projects where data ownership matters.
Pricing: Free tier includes 500MB database, 1GB storage. Paid from $25/month. Predictable pricing unlike Firebase's per-operation model.
Appwrite
Newest of the three. Open-source, self-hostable by design.
Strengths: Self-host on your own VPS for near-zero cost. Clean SDK for web, iOS, Android, Flutter. Functions (serverless) well-implemented. Storage with built-in image transformation.
Weaknesses: Smallest community. Less documentation. Cloud offering newer and less proven at scale.
Best for: Companies prioritizing data sovereignty, startups minimizing infrastructure costs, projects wanting to avoid US cloud vendor lock-in.
Pricing: Self-hosted is free (just server costs). Appwrite Cloud from $15/month.
The Indian Startup Lens
Data residency: Some Indian regulated industry clients require India-based data storage. Appwrite self-hosted on AWS Mumbai or Hetzner India solves this. Firebase and Supabase primary infrastructure is outside India.
Cost: Bootstrapped Indian startups find Appwrite self-hosted on a βΉ500/month VPS genuinely attractive.
Developer familiarity: Most Indian developers with 3+ years know SQL. Supabase's PostgreSQL foundation feels natural.
Quick Decision Guide
| Situation | Use |
|---|---|
| Mobile app with real-time/chat | Firebase |
| B2B SaaS with relational data | Supabase |
| Need to self-host, cost matters | Appwrite |
| Team knows SQL | Supabase |
| Need push notifications | Firebase |
| Data sovereignty matters | Appwrite |
Avoid the Lock-In Trap
Whatever you choose, abstract your database layer. Don't scatter platform calls throughout your codebase. Create a data access layer that you can swap. Takes an extra day up front β worth it for every project that survives past V1.
