Firebase
Proprietary SoftwareCloud Firestore database, authentication, hosting, and serverless backends by Google.
Why Teams Look for Firebase Alternatives
- Unpredictable read/write billing spikes on Cloud Firestore
- NoSQL querying limitations compared to standard relational SQL
- Vendor lock-in to Google Cloud infrastructure and proprietary security rules
- Difficulty running complete offline local staging environments
Hosting & Inference Reality
Open-source replacements like Supabase and PocketBase are 100% free software when self-hosted on your own VPS ($5–$20/mo server costs). Managed cloud tiers also offer generous free allowances.
Key Selection Factors
- Relational Postgres foundation (Supabase) vs. lightweight SQLite document stores (PocketBase)
- Self-hosting footprint: single Docker container vs. distributed microservices
- Built-in real-time subscriptions, auth providers, and S3-compatible storage
