Is This Website Built With Weebly?

How to Tell if a Website Uses Weebly

Identifying whether a website was built with Weebly used to require technical expertise — inspecting source code, tracing network requests in DevTools, and knowing which patterns to look for. Our free scanner automates all of that: it fetches the page, analyzes 3 Weebly-specific signals, and returns a verdict with a confidence score.

You might want to detect Weebly 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 Weebly?

Weebly is a drag-and-drop website builder owned by Square, primarily used by small business owners, entrepreneurs, and individuals seeking a straightforward platform for building e-commerce stores, portfolios, and blogs without coding knowledge. AIWebsiteDetector.com identifies Weebly-powered sites using a combination of 2 distinct script patterns and 1 HTML pattern, which together provide reliable fingerprinting of the platform's frontend architecture. The script patterns typically involve references to Weebly's proprietary CDN and JavaScript libraries embedded during page rendering, while the HTML pattern reflects structural markup signatures that Weebly's builder consistently outputs across its hosted sites. These signals remain stable across Weebly's free and paid tiers, making detection consistent regardless of whether a site uses a custom domain or the default `.weebly.com` subdomain. Weebly's tightly controlled rendering pipeline — a byproduct of its fully hosted, closed platform model — means the telltale patterns persist even when users apply custom themes, giving this detection profile a notably high degree of reliability.

It is primarily used for business websites, portfolios, landing pages, and personal sites without coding knowledge.

Signs a Website Is Built With Weebly

Our detection engine checks 3 unique Weebly fingerprints. Here are the most reliable signals:

High Confidence

JavaScript / Script Files

Weebly loads specific JavaScript runtime files or loads scripts from identifiable URLs. Checking script src attributes reveals the platform.

weebly.comeditmysite.com

Medium Confidence

HTML Attributes & Class Names

Weebly injects proprietary class names, data attributes, or markup patterns into the page HTML that are unique to the platform.

How to Manually Detect Weebly Websites

Method 1 — View Page Source

Open the website in your browser
Press Ctrl+U (Windows) or Cmd+Option+U (Mac)
Search (Ctrl+F) for weebly or weebly
If found in script src, class names, or meta tags — it's likely Weebly

Method 2 — Browser DevTools Network Tab

Press F12 to open DevTools
Click the Network tab and reload the page
Filter by weebly in the search box
If you see requests to Weebly-specific domains, it's confirmed

Faster: Skip the manual steps — paste the URL into our scanner above and we check all 3 signals in seconds.

How Our Weebly 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 3 Weebly-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

Frequently Asked Questions

How can I tell if a website was built with Weebly?

The most reliable ways to detect Weebly are: (1) open DevTools → Network tab and look for requests to Weebly-specific CDN domains, (2) view page source and search for Weebly-specific class names or data attributes, (3) use our free scanner — we check 3 detection signals automatically and return a confidence score.

Is your Weebly detector free?

Yes, completely free. Paste any URL into our scanner and we'll analyze it for Weebly fingerprints immediately. No account required, no limits on scans.

How accurate is the Weebly detection?

We check 3 unique Weebly fingerprint signals across HTML, JavaScript, CDN domains, meta tags, and HTTP headers. Our confidence score reflects how many signals matched — a score above 70% is a strong indicator. We cap accuracy at 99% to reflect that all fingerprint-based detection is probabilistic.

Can Weebly sites be detected if they use a custom domain?

Yes. Custom domains don't hide the underlying platform. The JavaScript files, CDN requests, HTML attributes, and server headers all remain identifiable regardless of the domain name used. Our scanner fetches the page directly and analyzes its technical composition.
