Musbu on new websites

1. Musbu appeared on 13 new sites in the last 30 days.^[1]
2. Almost all new Musbu sites also use Moment Timezone.

The line is the 7-day average share of new sites that use Musbu, day by day for the last 90 days and weekly before that (left of the dashed line). It starts at our first detection. The shaded areas were measured against a different set of sites, so the line can step there without Musbu itself changing.^[2][3]

Tools that turn up far more often on Musbu sites than on new sites in general, and how many times as common each one is there.

None of them is a product launch we list individually, so there is nothing to show here. They still count towards the figures above. How StackScope Discovery works

The StackScope API serves all 55 sites using Musbu, filterable and exportable, from £15 a month.

1. These figures cover websites that went live since April 2026, not the web as a whole.
2. Grey: before 8 July 2026, we only tracked launches from launch platforms. From that date we crawl the wider web as well, so the share is measured against a much larger set of sites. For one continuous measure, view launch platforms only.
3. Amber: 8 July to 10 September 2026, before we improved our infrastructure to index new sites much sooner, often on the day they go live. Sites found that early often haven't finished setting up, so anything usually added after launch reads lower from 10 September. We record each site as it was when we found it.
