ASP.NET
Backend Framework
Webflow
Website BuilderASP.NET and Webflow are both popular choices, but they serve different needs. ASP.NET is a Backend Framework with a traditional, manual approach to building, while Webflow is a Website Builder that prioritises developer or designer control.
Below you'll find a side-by-side breakdown of detection signals, AI scores, and technical fingerprints — plus our honest take on which builder wins for different use cases.

Backend Framework
ASP.NET is a backend framework with an AI Score of 10/100 (Unknown). Our detection engine uses 4 signal patterns to identify ASP.NET-built sites.
Website Builder
Webflow is a website builder with an AI Score of 30/100 (No-Code / Visual Builder). Our detection engine uses 13 signal patterns to identify Webflow-built sites.
ASP.NET is Microsoft's web application framework, spanning the older .NET Framework-based Web Forms/MVC stack and the modern cross-platform ASP.NET Core, widely used in enterprise, government, and Windows-centric organizations. AIWebsiteDetector identifies ASP.NET deployments through the `X-Powered-By`/`X-AspNet-Version`/`X-AspNetMvc-Version` response headers Microsoft's runtime adds by default, and — for older Web Forms applications — the `__VIEWSTATE` hidden field that ASP.NET's page lifecycle injects into every form.
Webflow is a visual web design and development platform used by designers, agencies, and marketing teams to build responsive websites without writing code, though it generates clean, standards-compliant HTML and CSS under the hood. Sites built on Webflow are reliably identified through a combination of technical signals, including 3 distinct JavaScript script patterns loaded from Webflow's asset pipeline, 4 characteristic HTML attributes and structural patterns embedded in the page markup, 2 CDN domain signatures used to serve static assets, 2 HTTP response headers that indicate Webflow's hosting infrastructure, and 2 meta tag patterns injected into the document head. These overlapping signal layers allow AIWebsiteDetector.com's detection engine to identify Webflow-powered sites with high confidence across a wide range of site categories, from portfolio and agency sites to SaaS marketing pages and e-commerce storefronts. Webflow is unique in that it offers both a hosted platform (webflow.io subdomains and custom domains routed through its CDN) and the ability to export code for self-hosting, though the exported code still retains several of Webflow's structural HTML fingerprints, making detection possible even in non-hosted deployments. The platform's official presence is at webflow.com, and its hosting tier ranges from free plans with branded subdomains to enterprise plans with advanced CMS and logic capabilities.
