Broken links with source pages, not just a URL list

The demo uses Olostep Maps to discover URLs, then Scrapes with links_on_page to extract and check outbound links.

  • Site discovery

    Maps lists discoverable URLs, including paths that are not in a sitemap.

  • Link extraction

    Each page scrape returns absolute outbound links.

  • Source tracking

    See which page a dead link was found on so you can fix the right file.

How it works

Each tool is designed around a direct job: provide the input, get a useful output, and move it into your workflow.

  • 1

    Enter a start URL

    Add your Olostep API key. Optionally cap pages and depth.

  • 2

    Discover and scrape

    Maps finds pages; scrapes extract links and status codes.

  • 3

    Export the table

    Download broken links with the pages that pointed to them.

Built for practical workflows

These tools are small on purpose: they solve the conversion job quickly, then point teams toward the API path when the workflow becomes recurring or high volume.

  • Docs QA

    Catch dead links in a docs or blog site before a release.

  • SEO cleanup

    Find 404s that waste crawl budget.

  • Migration checks

    Verify old paths after a site move.

Need this at scale?

Use POST /v1/maps to discover URLs, then POST /v1/scrapes with links_on_page. The snippet on this page is that two-step flow.
