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.

That file is the exact data this site’s catalogue is generated from - not a summary of it. The checksum is computed at build time, so you can verify the download is what we built with. 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.
