UnQLite is a self-contained, serverless, transactional NoSQL database engine implemented as an embeddable C library. It provides both a binary-safe key/value store and a JSON document store powered by the Jx9 embedded scripting language, storing an entire database in a single portable file.

Use cases

• embed a lightweight NoSQL database in a C/C++ application
• store key/value records locally without running a database server
• persist JSON documents in a single portable file
• replace SQLite-style embedded storage with a document store
• build an in-memory database for temporary application data
• ship a zero-configuration database with a desktop or embedded application

When to choose

• you need an embedded, serverless database with no external dependencies
• you want ACID transactions for local storage in C/C++
• you need a single cross-platform database file that is easy to distribute
• you want both key/value and JSON document storage in one small library
• you target restricted or embedded platforms with a C compiler

When to avoid

• you need a client/server database accessed over a network
• you require SQL queries or a rich relational model
• you need heavy concurrent multi-process write access
• you depend on an actively maintained project with frequent updates
• you need bindings beyond C/C++ without writing your own wrapper
