WeWeb is a no-code and low-code frontend builder targeting product teams and developers who need to construct data-driven web applications without writing traditional frontend code from scratch, connecting visual interfaces to any backend or API. Our detection engine identifies WeWeb-powered sites through a combination of 3 distinct script patterns, 3 HTML structural patterns, and 1 meta tag signature embedded in the page markup, alongside fingerprinting against 2 known CDN domains that WeWeb uses to serve its runtime assets. These signals appear consistently across WeWeb deployments, giving the detection engine reliable, high-confidence identification regardless of whether the site uses a custom domain or WeWeb's own hosting infrastructure. WeWeb sites are characteristically distinguished by their reliance on a Vue.js-based rendering engine delivered through WeWeb's CDN layer, making the script and domain patterns particularly stable detection anchors across versions. For teams evaluating the no-code app builder landscape, WeWeb occupies a notable niche as a frontend-focused platform that pairs with external data sources rather than bundling a full backend, a architectural pattern that leaves consistent, identifiable traces in the delivered HTML that our scanner reliably surfaces.
