Dr Link Check vs Bulk URL Checker: when to pick which.

Dr Link Check is a clean tool for crawling a single domain and finding broken outbound links. If your job is checking a list of URLs (backlink exports, sitemaps from multiple clients, content audit lists), it's the wrong shape. Here's the honest comparison.

What Dr Link Check is good at

Dr Link Check (drlinkcheck.com) is a hosted single-domain crawler. You paste a URL, it crawls the site, it reports broken outbound links found inside that crawl. For a personal blog or small site, it's a good lightweight tool with a clean UI.

If you just want "here are the broken outbound links on my one website," Dr Link Check answers that well.

Where it stops fitting

The case that comes up over and over in Reddit threads asking for a Dr Link Check alternative is: I have a list of URLs, not a website to crawl. For example:

Backlinks export from Ahrefs / Semrush / Majestic. You want to check which ones are still live, but they're not on one domain.
A client's sitemap with 50,000 URLs. You want to validate redirect chains and current status before a migration.
Multiple clients' URL lists. You want them in separate buckets, not mixed into one crawl.
Outreach prospect lists. You want to check that the URLs you collected still resolve before sending the email.
Documentation outbound links across many pages and many target domains. Same shape: a list, not a site.

Dr Link Check assumes you have one domain to crawl. We assume you have a list of URLs, possibly from multiple sources, possibly assigned to multiple clients.

Honest comparison

	Bulk URL Checker	Dr Link Check
Best for	Bulk URL list checking, multi-client	Single-domain outbound link crawl
Input shape	Paste list, CSV, sitemap, API	One domain URL
Max URLs per run	75,000	Limited per plan
Multi-client workspaces	Up to 20 isolated buckets	No
Anti-block layer	Proxy rotation + rate limits	Basic
Scheduled monitoring	Daily, automatic	Limited
White-label PDF reports	Yes, your branding	No
Slack alerts on broken links	Yes, per workspace	No
API + MCP for agents	Yes	No

If you're an SEO agency

The shape we built around is multi-client recurring link health. Drop a client's URL list (from Ahrefs export, Semrush, GSC, Majestic, or just a CSV) into a workspace tagged for that client. Set a daily or weekly schedule. The white-label PDF lands in your inbox at the end of each cycle, branded as your agency, ready to forward to the client.

Pricing is shaped for the re-bill model: at $499/month with 20 client workspaces and 2 million URL checks per month, the math works out to roughly $25 per client per month for a recurring deliverable you can re-bill at $50 to $150.

If you're a developer or content team

Same engine, different surface. Use the REST API or MCP server (Claude.ai, ChatGPT, Cursor) to call URL checking from your own code or AI workflow. Free tier covers 300 URLs to test with.

Honest answer to the recurring Reddit question

When someone asks "is there a Dr Link Check alternative?" the answer depends entirely on what they're actually trying to do:

Crawl one site for broken outbound links: Dr Link Check is fine. So is linkchecker (Python CLI, free).
Check a list of URLs at scale: that's what we built. Try the free tier (300 URLs) and see if it fits.
Run monthly link health for multiple clients: that's the agency tier specifically.
