SiteStacks for Web

Quick summary of the service

SiteStacks is an online tool that reveals the underlying technologies used by any public website. It’s built to index large numbers of sites and give you a snapshot of the frameworks, analytics, hosting, and other software components they rely on.

How the platform operates

The system crawls and inspects websites to identify installed tools and libraries. It’s capable of processing thousands of URLs, and when a site you care about is missing, you can submit it for review — after the team verifies the findings, the site will be added to the index.

Scope of the database

• Maintains data on roughly 20,000 distinct software products spanning over 60 different categories.
• Able to analyze and catalog the tech stacks of several thousand websites.
• Accepts user suggestions for sites that aren’t currently tracked and adds them following validation.

Suggested alternative

If you’re looking for another option, consider SEMrush — a broadly used platform that offers some free capabilities for competitive and technology research.
