Free public resource

A shared language for software technologies.

The Queast technology taxonomy is a structured catalogue of software technologies: their names, aliases, categories, and relationships. It is free for anyone to browse and use in their own projects.

Why it exists

Technology names change. Your reference should hold together.

The same technology can appear under different names across job advertisements, company websites, and datasets. Products get renamed, abbreviations vary, and a flat list of names tells you little about how technologies relate.

Queast maintains the taxonomy to give those names a consistent reference. Stable IDs preserve identity, aliases connect alternative names, and classifications and relationships add context. Teams can use the same vocabulary across their software, analysis, and research.

What is inside

More than a list of names.

Explore languages, frameworks, libraries, databases, platforms, tools, and other technology concepts in one public catalogue.

01

Identity

Stable technology IDs, canonical names, and aliases help you recognise the same technology across different sources.

02

Context

Categories, domains, and typed relationships help explain what a technology is and how it connects to others.

03

Review history

Published records come from reviewed, versioned releases. Source links and review dates are shown where available.

Free to use

For anyone. For your own projects.

You do not need to be a Queast customer to use the taxonomy. Browse the catalogue, download a versioned JSON release, or use it as a reference in your own tools and research.

The taxonomy dataset is published under CC0-1.0. You can copy, modify, and redistribute it. See the dataset license for its scope and details.
