Tools & Libraries Used
This page provides a complete summary of all open-source components used within the TraQez platform — including libraries, SDKs, operating systems, and infrastructure tools.
All listed components are verified for commercial use, comply with permissive open-source licences, and are aligned with industry best practices for security and support.
1. Overview
TraQez leverages a secure, modern, and modular open-source stack spanning:
- Cloud SDKs (AWS, Azure, Google)
- Middleware libraries
- Backend frameworks (Express, BullMQ)
- Infrastructure (PostgreSQL, Redis, Kafka, Nginx, Ubuntu)
- Programming runtimes (Node.js, Python)
- Container orchestration (Docker, Kubernetes)
Each component is approved for use in commercial environments and can be safely distributed with proprietary code.
