SQLite Alternatives
Alternative choices depend on data model, consistency requirements, and operational complexity tolerance. Consider these options when SQLite’s limitations become constraints.
¶ 
PostgreSQL
Best for: Multi-user server workloads, complex queries, advanced features
- Strengths: Advanced SQL features, JSON support, extensibility, ACID compliance
- Use when: Need server-based database, complex relationships, or advanced analytics
- Migration path: Well-supported migration tools available
- Reference: PostgreSQL
¶ 
MySQL/MariaDB
Best for: Broader managed-service compatibility, traditional SQL workloads
- Strengths: High performance for read-heavy workloads, mature ecosystem
- Use when: Need server-based database with familiar SQL syntax
- Migration path: Similar SQL syntax to SQLite with minor adjustments
- References: MySQL, MariaDB
¶ 
LiteFS/Litestream
Best for: SQLite with replication capabilities
- Strengths: SQLite-compatible with streaming replication, failover capabilities
- Use when: Want SQLite’s simplicity but need high availability
- Note: Relatively new technology compared to traditional databases
¶ 
SQLCipher
Best for: Encrypted SQLite databases
- Strengths: Drop-in replacement for SQLite with 256-bit AES encryption
- Use when: Need encryption at rest for SQLite databases
- Note: Maintains SQLite’s API compatibility
¶ 
Cloud SQL Solutions
Best for: Managed database services
- AWS DynamoDB: NoSQL, serverless, auto-scaling
- Google Cloud Firestore: Document database with real-time sync
- Azure Cosmos DB: Globally distributed, multi-model database
¶ 
Embedded Alternatives
Best for: Embedded systems with different requirements
- LevelDB: Google’s fast key-value store
- RocksDB: Facebook’s embeddable database based on LevelDB
- LMDB: Lightning Memory-Mapped Database, very fast read performance

Selection Notes
- Match your choice to operational skills and backup/recovery maturity.
- Validate client-library compatibility before migrations.
- Benchmark with production-like data and concurrency patterns.
- Consider hybrid approaches (e.g., SQLite for edge, PostgreSQL for central storage).
- Evaluate total cost of ownership including operational complexity.
