webR has been detected on 5 launches since first appearing in July 2026. Most recent detection: AskStat — an AI that answers with data and verifiable code, on August 18, 2026.
It's most commonly paired with HSTS, NS1, and Netlify.
Share of new sites using webR
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.
