Pros & Cons
12 pros·6 cons across both
Firebase (by Google)
Pros
- Real-time Firestore database with 50ms latency for multi-region sync
- Integrated Google Authentication and 10+ social login providers
- Cloud Functions with 540,000 GB-seconds free monthly quota
- Analytics dashboard with 500+ pre-built events tracked automatically
- ML Kit integration for on-device vision, NLP, and translation models
- Enterprise SLA with 99.95% uptime guarantee
Cons
- High variable costs at scale ($0.06 per 100k reads, compounds rapidly for heavy apps)
- Proprietary vendor lock-in with non-standard query language (Firestore queries don't transfer)
- Limited offline support compared to traditional databases (eventual consistency only)
Appwrite
Pros
- 100% open source (MIT license) with full codebase transparency and community contributions
- Self-hosted option with zero per-request costs (pay only for infrastructure)
- Fixed transparent pricing ($99-$999/month for cloud) with no surprise usage charges
- Standards-based REST and GraphQL APIs (easier migration path to other backends)
- Built-in file storage with 2GB free on cloud tier, unlimited on self-hosted
- User permissions system with granular role-based access control (RBAC)
Cons
- Smaller ecosystem with 40% fewer third-party integrations than Firebase
- Real-time sync is websocket-based with 100-200ms latency vs Firebase's 50ms
- Requires DevOps knowledge for self-hosting (Docker/Kubernetes), adding operational overhead
Frequently Asked Questions
5 questions
Not necessarily. Firebase's usage-based pricing ($0.06 per 100k reads, $0.18 per 100k writes) can exceed Appwrite's fixed plans ($99-$999/month) by 400%+ for data-heavy apps with 10M+ monthly operations. For low-traffic MVPs (<100k monthly reads), Firebase's free tier is cheaper. For production apps with predictable growth, Appwrite's fixed pricing offers better financial certainty.
