Licenses and attribution
Where the technology catalogue comes from, under which licence, and how to get the data it is built from.
Technology catalogue
The technology pages on this site are built from a community-maintained catalogue of technology definitions, licensed GPL-3.0. Those definitions are that community’s work, not ours. What we add is the scoring, the version history and the analysis around them.
Because we publish pages built from those definitions, we distribute a derived work. Under GPL-3.0 that means the licence travels with it, and the corresponding source is offered below.

- Our own scoring weights have been removed. They are not part of the upstream GPL-3.0 work and are not read by any step that builds these pages. Everything that comes from the upstream catalogue is present in full.
Everything the upstream catalogue contains is in that file, in full - every technology, every detection pattern, every category. The one thing removed is our own scoring weights: they are not part of the upstream work, and no step that builds these pages reads them. The checksum is computed at build time, so you can verify the download is what we serve. No upstream version is quoted because the definitions are taken as a snapshot of the project’s main branch, which carries none - the checksum identifies it instead.
Everything else
Audit results, scores and the analysis around them are ours. The Lighthouse audit is Google’s open-source tool. Where a technology page shows a project’s own name, logo or description, those belong to that project.
