Sitemap Generator for Web

Quick summary

Sitemap Generator is a free, browser-based utility created by independent developer Nacho Mascort that helps web professionals build a link map (sitemap) for a website. It’s designed to extract and organize URLs so developers and designers can audit link structure, verify destinations, and study how other sites organize their pages.

Main capabilities

• Processes multiple sites and page lists in a single session, producing organized maps.
• Creates XML sitemaps and can also export plain text lists for large projects.
• Automatically splits very large collections into separate XML files and generates an index for easier navigation.
• Works entirely in the browser, so it’s platform-independent and doesn’t require installation.

How it handles large inputs and multiple domains

• You can paste up to 10,000 URLs into a single XML output.
• For very large exports (50,000 URLs or more), use the plain text export option.
• When you feed it links from several top-level domains (for example, .com, .net), the tool separates them into multiple XML files and adds proper indexing so the results remain easy to browse.

Who will benefit from this tool

This is aimed at experienced web developers and site administrators who prefer hands-on control over site structure. Beginners may encounter a learning curve, as understanding sitemap conventions and XML indexing helps get the most out of the utility.

Typical uses

• Audit your own site’s internal links to ensure each URL points where it should.
• Inspect competitors’ or model sites to learn how they organize pages and navigation.
• Generate sitemaps for large websites that need subdividing and indexing for search engines.
