Detect all tags

Other solutions detect against a predefined list of tags, but WASP uses a powerful algorithm to detect all tags, even the most obscure ones.

Unlimited crawls

Crawl up to 100 pages on any website, or purchase a license to crawl up to 10,000 pages on a domain, as often as you like.


Tweak the crawl to include/exclude specific pages or sections of your site, detect tags, or grab anything on the page.

Tableau Reader

WASP.crawler reports are available in Tableau Reader format, making it much more powerful and flexible to spot anomalies in your implementation.

Runs locally

WASP.crawler is the only solution that runs locally, so it can be used on intranets and secured environments without opening security holes.


Use our free tools, or purchase an affordable domain-specific license. At Cardinal Path we strongly believe quality assurance should be affordable and easy.

Compliance audit

Use WASP.crawler to validate if your website conform to regulations and best practices related to privacy.

What do people think?

Easy to use, efficient, flexible and affordable; I’ve been auditing with WASP.crawler for some time (free and now paid-for version) and the one thing I can say, hands down, is that when it comes to enforcing quality assurance WASP.crawler does a superb job for an incredible cost/benefit ratio.

R.Rodrigues Web Analytics Manager,

I have used WASP since its beginning when other such tools were cumbersome and expensive to use. WASP was a breath of fresh air that made access to data quality tools a no-brainer. I highly recommend it for anyone that takes data quality seriously.

Brian Clifton Author and Consultant,

Ensuring your digital analytics data is collected correctly and completely is the foundation of optimal decision making. WASP makes this process amazingly efficient!

Frequently Asked Questions

What's the difference between WASP.inspector and WASP.crawler?

The WASP.inspector is a Google Chrome browser extension specifically aimed at providing in-context information about the tags present on a page, as you browse. The WASP.crawler brings that power into a Google Chrome App which runs on your computer, goes out and crawls a given website, pulls in detailed information about the tags and gives you a nicely formatted, easy to use Tableau Reader dashboard.

Can you help me with my audit?

Conducting an audit, ensuring proper instrumentation, and gathering good data requires specific expertise: intimate knowledge of the website content architecture, mastery of functional features found on the site, technical knowledge of how to instrument the site, administrative knowledge of the specific tool, understanding of the digital strategy, and more. Cardinal Path conducts audits for leading global brands. Contact us for a quick chat to get started.

Why audit my site?

What's worse: making critical decisions based on flawed data or making decisions without any data? We've seen countless cases of poorly implemented tags and a lack of trust in the data, which negates the value of digital analytics. A sound audit plan will empower analysts with more accurate data and confidence in their recommendations.

What makes WASP unique?

Here are some specific points:

  • Innovation & leadership: WASP is developed and maintained by the leading digital analytics consultancy, Cardinal Path
  • Experience: initially created in 2006, we've stacked a huge amount of expertise when it comes to complex audits
  • Completeness: WASP is the only solution that doesn't rely on a limited list of tags or risk becoming obsolete very fast as tags evolve
  • Flexibility and power: WASP runs within your premise, using the untapped power of your own computer for unlimited crawls.
