sqlite_orm
sqlite_orm is a header-only C++ library providing type-safe ORM functionality for SQLite databases with minimal dependencies. It uses modern C++ (C++14/17/20) to eliminate raw SQL strings while supporting CRUD operations, joins, transactions, and migrations.

What sqlite_orm is
Header-only ORM built on template metaprogramming for compile-time query generation and type safety. Supports prepared statements, composite keys, foreign keys, custom type binding, BLOB mapping, and common SQL operations (UNION, GROUP BY, ORDER BY, LIMIT) without macros or code generation.

Best use cases
Implementation considerations
- Requires explicit storage configuration mapping each table and column; schema changes demand code modification and recompilation.
- Header-only design increases compilation time; consider precompiled header strategies and incremental build optimization.
- Primary use case is single-threaded or low-concurrency applications; SQLite's file-locking model can bottleneck high-concurrency workloads.
- Member pointers used in column definitions are tied to C++ struct layout; refactoring data models requires careful migration of ORM configuration.
- Exception-based error handling for operations like `get()`; use `get_pointer()` for non-throwing nullable semantics.
When to avoid it — and what to weigh
- Closed-Source Commercial Products Without License Purchase — AGPL-3.0 licensing requires purchasing an MIT license (~$50) for proprietary use. Shipping without explicit license compliance creates legal exposure.
- Large-Scale Distributed Systems — sqlite_orm is designed for SQLite (single-file, embedded database). Not suitable for systems requiring multi-node RDBMS, complex sharding, or high-concurrency server deployments.
- Teams Unfamiliar with Modern C++ — Heavy reliance on C++14/17/20 template metaprogramming and member pointers requires intermediate-to-advanced C++ expertise; steep learning curve for junior teams.
- Projects with Complex, Evolving Schemas — While migrations are supported, breaking schema changes require C++ recompilation and redeployment. Runtime schema flexibility is limited compared to dynamic query builders.
License & commercial use
Licensed under AGPL-3.0 for open-source projects (source code must be disclosed and available under same terms). Commercial/proprietary use requires purchasing MIT license (~$50 via PayPal or direct contact). Dual licensing model is explicit in README.
Proprietary software use is NOT permitted under AGPL-3.0 without license purchase. Purchasing a separate MIT license is required for closed-source products. Confirm license acquisition before integrating into commercial codebases. No other commercial terms, SLAs, or enterprise support visible.

Type-safe query generation eliminates common SQL injection vectors by design. Prepared statements supported. No explicit security audit, penetration testing results, or vulnerability disclosure process mentioned. Rely on underlying libsqlite3 for encryption/authentication features (e.g., SQLCipher integration not documented). Review custom type binding and BLOB handling for application-specific data protection.
Alternatives to consider
sqlpp11
Header-only SQL library with similar type-safe query generation and modern C++. Vendor-agnostic (supports multiple databases). More mature query DSL but steeper learning curve.
SOCI (C++ Database Access Library)
Multi-database ORM with permissive Boost license. Less modern C++ syntax but broader platform/database support and longer community history.
nanodbc / Direct SQLite3 API
Lightweight C++ wrapper around native SQLite C API. Manual SQL required but maximum control, zero abstractions, and no licensing constraints. Suitable if type safety trade-off acceptable.
