Share of new sites using United States Semantic Standard
Each dot is one launch day. Line is the 7-day rolling average. Chart starts at first detection.
The shaded part of the chart is measured against a different set of sites. Until 8 July 2026 we only tracked launches from launch platforms; from that date we crawl the wider web as well. The share is a proportion of whatever we were tracking at the time, so it can step at that line without the technology itself changing. For a single continuous measure, switch to launch platforms.

Recent launches we can show
0 of the 28 sites using United States Semantic Standard are product launches we list individually. The other 28 are sites we found crawling the wider web: they count towards the figures above, but we do not publish them one by one. How StackScope Discovery works
Every site we have found using United States Semantic Standard came from crawling the wider web rather than a product launch, so there is nothing to list here. The 28 still count towards the figures above. How StackScope Discovery works
