What WCDB is

WCDB is an open-source database framework based on SQLite and SQLCipher, used in the WeChat application. It provides interfaces for C++, Java, Kotlin, Swift, and Objective-C, and is available for Android, iOS, Linux, macOS, and Windows. Its ORM handles table, index, and constraint creation along with CRUD operations through language objects. WINQ offers a way to express queries in native language syntax rather than assembling SQL strings. Connection pooling supports concurrent read-read and read-write access. WCDB also supports SQLCipher encryption, describes built-in SQL injection protection, and includes a repair kit for database corruption recovery. Other capabilities include full-text search with tokenizers for multiple languages, configured migration between databases, and Zstd compression for selected table fields. The project describes optimizations for mobile use, including batch writes, and links build guides and programming-language tutorials. WCDB is free, with a listed price of no cost.
