# JDBX



> 🚀 **This codebase was developed using [Extreme Vibe Coding (XVC)](https://github.com/osakka/xvc)** 🚀

>

> JDBX is a testament to the power of XVC methodology - the entire codebase, including architecture, implementation, testing, and documentation, was created through structured human-model collaboration using reasoning models built on human knowledge. This represents approximately 3 months of intensive development that would traditionally require 12-18 months of solo developer effort.

JDBX is a high-performance document database built specifically for JSON data, featuring **TRUE unified documents architecture** and capable of handling billion-document collections with sub-millisecond response times. Written in C for maximum performance, JDBX stores ALL entities (users, roles, libraries, configs, metrics) as documents in a single unified collection, providing unprecedented architectural simplicity while maintaining enterprise-grade performance. With native JavaScript integration, comprehensive RBAC, and a complete RESTful API, JDBX represents the future of document database design.
