You might want to detect Durable for competitive research, due diligence before acquiring a site, or simple curiosity. Whatever the reason, this page covers every method — automated and manual.
What is Durable?
Durable is an AI website builder designed for speed — it generates a complete multi-page business website including copy, images, layout, and a contact form in under 30 seconds. Targeted at local businesses, consultants, and service providers who need to be online quickly, Durable handles the entire creation process from a business name and industry alone. The platform includes built-in CRM tools, invoicing, and SEO features, making it more than just a website builder for service businesses. Durable sites are served through their proprietary CDN (cdn.durable.co) and contain platform-specific markup patterns in their HTML. Pricing starts at a free tier with a Durable subdomain, with Pro plans from $12/month that include a custom domain.
It is primarily used for marketing sites, landing pages, portfolios, and business websites — all generated from prompts or visual editors with AI assistance.

How Our Durable Detector Works
When you submit a URL, our engine fetches the page from its server — just like a browser would — then analyzes the response across 14 Durable-specific fingerprints:
Script analysis
We scan all loaded JavaScript files for known CDN paths and runtime names
CDN domain matching
We cross-reference every asset request against known platform CDNs
HTML pattern scanning
We search the DOM for platform-specific class names and data attributes
Header inspection
We read HTTP response headers that identify the server or platform
Meta tag extraction
We check generator and other meta tags in the document head
Confidence scoring
We weight each matched signal and normalize to a 0–99% score
