PUBLIC DEVELOPER REFERENCE
A free software technology taxonomy.
An open software technology taxonomy for people, applications and AI agents. Use stable IDs, available aliases and classifications through JSON downloads, the API and MCP under the selected dataset license: CC-BY-SA-4.0.
technologies.quea.st is a public reference catalog maintained by Queast for developers, data teams and researchers. Browse IDs, names, aliases, categories, and relationships, then reuse the selected release in software and research.
Release 2026.10.7 contains 1,467 technology records.
USE THE DATA
Use the taxonomy in your application or research
Public pages are generated from a selected, immutable release. Maintainers review record changes and supporting source links before they enter a release.
What is a software technology taxonomy?
A maintained reference for identifying software technologies consistently across systems, datasets, and research. Our inclusion policy requires at least two distinct job advertisements in the last 12 months, found by full-text searches of job-ad titles and descriptions for the candidate name and aliases.
Read the methodologyWhat does a record contain?
Stable IDs, names, aliases, lifecycle, classifications, typed relationships, review dates, and source links when included.
Browse all recordsBrowse released classifications: Continuous integration and delivery · Infrastructure as code · Programming languages · Cloud platforms · Cloud and infrastructure · Software delivery and quality
How can I reuse the data?
Download a versioned JSON release, query the HTTP API, connect an agent through MCP, or track the public repository on GitHub.
How can I suggest a change?
Check the contribution status and proposal requirements before sending a new technology or correction. Proposals are reviewed before publication.
