XML Sitemap Generator

The Easiest Way to Generate Perfect XML Sitemaps for Any Website

XML Sitemap Generator is a modern web application that makes creating SEO-optimized sitemaps effortless. Simply enter your website's URL, watch the real-time crawl progress, and download a fully compliant XML sitemap ready for Google, Bing, and other search engines.

The Problem It Solves

SEO is crucial for any website's success, and XML sitemaps are fundamental to getting indexed by search engines. But creating sitemaps manually is tedious, error-prone, and time-consuming especially for large websites. Existing tools are often:

Expensive with monthly subscriptions
Limited to small numbers of pages
Lacking support for modern JavaScript-rendered sites
Missing real-time feedback during crawling

XML Sitemap Generator solves all of these problems with a free, open-source solution that handles both traditional and modern web architectures.

Key Features

Intelligent Crawling

The crawler is smart enough to handle real-world websites:

Crawls up to 1000 pages per site (configurable from 10-1000)
Seamlessly handles Server-Side Rendered (SSR) pages
Supports Client-Side Rendered (CSR) pages using Puppeteer headless browser
Automatically extracts internal links while avoiding non-HTML resources
Concurrent processing with configurable batch sizes for optimal performance

Ethical & Compliant

Being a good web citizen is built into the core:

robots.txt Compliance: Automatically fetches and respects disallow rules
Priority-based Sitemap: Assigns intelligent priority values based on page depth (1.0 for homepage, decreasing by 0.1 per level)
Standards Compliant: Generates XML sitemaps following the official Sitemaps.org protocol
lastmod Support: Includes last-modified dates from HTTP headers when available

Real-time Progress Tracking

Watch your sitemap being built live:

Server-Sent Events (SSE) streaming for instant feedback
Live display of current URL being crawled
Running total of discovered pages
Progress indicator showing crawl status
No page refreshes needed everything updates in real-time

Hybrid Rendering Support

This is what sets this tool apart, it handles modern web applications:

Traditional server-side rendered pages are crawled quickly with Cheerio for HTML parsing. JavaScript-heavy single-page applications (SPAs) are rendered with Puppeteer to extract dynamically loaded content. The crawler automatically detects which approach to use for each page.

Technical Implementation

Backend Architecture

Sitemap Generation

Produces fully compliant XML output:


xml
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <url>
    <loc>https://example.com/</loc>
    <lastmod>2025-12-27T12:00:00.000Z</lastmod>
    <priority>1.0</priority>
  </url>
  <!-- Additional URLs... -->
</urlset>
