Crawl your whole site in the cloud
Spider from a seed URL or feed a sitemap, render JavaScript with headless Chromium, and stream every result in real time — up to 500,000 URLs per crawl. No desktop install, no local memory ceiling.
Spider the whole site, or crawl just your sitemap
In spider mode, CrawlX starts at a seed URL and follows links recursively across the site — surfacing orphan pages that no sitemap ever lists. In sitemap mode, it crawls exactly the URLs you publish. Either way it respects robots.txt and crawl-delay, so you stay a good citizen of your own infrastructure.
Crawl configuration
● readySee what your users see — not just what ships in the HTML
CrawlX renders every page in headless Chromium, then compares the raw HTML you serve against the JS-rendered DOM. The render diff flags content, links, and canonicals that only appear after rendering — the exact gaps that cost SPAs their rankings.
Scheduled crawl
activeSet it once, watch the trend line
Schedule a crawl to run daily, weekly, or monthly and CrawlX handles the rest in the cloud — no machine left running overnight. Every run lands an email alert on completion, so you catch regressions the morning they happen instead of the week you go looking.
Built to crawl anything
Six capabilities that let one cloud crawl stand in for a rack of desktop machines.
Spider mode
Recursively follows links from a seed URL to map your whole site — including orphan pages no sitemap ever lists.
Sitemap mode
Point CrawlX at an XML sitemap (or a sitemap index) and crawl exactly the URLs you publish, nothing more.
JavaScript rendering
A headless Chromium engine executes your JS and crawls the rendered DOM, so SPA and client-rendered content is never missed.
Scheduled crawls
Run daily, weekly, or monthly on autopilot and get an email the moment a crawl finishes — track regressions over time.
Real-time results
Watch URLs stream in one by one as they're crawled, with status, issues, and load time — no waiting for a batch to finish.
Crawl at scale
Up to 500,000 URLs per crawl on Agency. It runs in the cloud, so there's no desktop install and no local memory ceiling.
Cloud crawling vs the desktop tools
Screaming Frog and Sitebulb are excellent — here's where running in the cloud wins, and where they still lead.
| Capability | CrawlX | Screaming Frog | Sitebulb |
|---|---|---|---|
| Runs in the cloud (no install) | Cloud | Desktop | Desktop |
| Local memory ceiling on big sites | None | RAM-bound | RAM-bound |
| JavaScript rendering (headless Chromium) | Yes | Yes | Yes |
| Real-time streaming results | Yes | Partial | Partial |
| Render diff (raw vs rendered) | Yes | Manual | Manual |
| Scheduled crawls + email alerts | Built-in | Scheduling add-on | Yes |
| Visual crawl maps | On roadmap | No | Mature |
