Pull a client's URL list. Run it. Send a branded PDF. Repeat next month. This page is for the agency owner who's done that 50 times and finally wants a tool that handles the whole thing without an analyst's morning.
Most tools are built for one person checking one site. Agencies have 20 clients, monthly deliverables, scope creep, and zero patience for an analyst spending 4 hours a month wrestling Sheets.
We modeled this after how the agencies we talked to actually deliver link health to clients. Four steps the first time you onboard a client, one step every month after that.
Create a workspace, upload their logo, set the brand color. Drop in the URL list from Ahrefs / Semrush / GSC. Once.
Daily, weekly, or monthly. We schedule the recurring check, rotate proxies, respect each domain's rate limits. You don't look at it.
At the end of each cycle a PDF generates with the client's logo, your branding, the executive summary, the broken-link table, the trend over time. Attached to an email, ready to forward.
When something breaks mid-cycle, your team channel sees it before the client does. You email them with a fix already in motion. That's the agency move.
We're not trying to replace your full SEO stack. We're the recurring link-health layer that's missing from it.
| Bulk URL Checker | Screaming Frog | httpstatus.io | Ahrefs Audit | |
|---|---|---|---|---|
| URLs in one run | 75,000, cloud | Limited by your laptop | Stops at 100 | Per-site only |
| Anti-block layer | Proxy rotation + rate limits built in | You handle it | None | N/A |
| Multi-client | Up to 20 isolated workspaces | One project at a time | One list at a time | Per-seat math gets ugly |
| Scheduled monthly delivery | Yes, automatic | Manual cron + script | No | Per-site only |
| White-label PDF | Yes, your branding | No | No | Limited templates |
| Slack alerts on broken links | Yes, per workspace | No | No | Email only |
The agencies we've talked to charge $50 to $150 per client per month for a link audit deliverable. With 20 clients, the math is straightforward.
Everything you need to run link health for up to 20 clients.
Hi, Carlos here. I'm the developer behind this and I'm running it as a one-person shop. The reason this page is shaped for SEO agencies is straightforward: every time someone reached out to ask about bulk URL checking at scale, the conversation eventually turned out to be the same conversation. They had a roster of clients, a monthly deliverable, and a workflow held together with tape.
The engine itself has been running in production for over a year, checking millions of URLs across many job types. The proxy rotation, per-domain rate limiting, and retry classification that make it actually work at scale, those are the months of unsexy plumbing nobody else wants to write.
The agency-shaped layer on top, multi-client workspaces, the white-label PDF, the Slack alerting, the scheduled-delivery rhythm, that's what I'm building now and onboarding design partners for. If that sounds like the tool you wished existed three months ago when you were rebuilding your link audit template for the third time, get on the list. You'll hear from me directly, not a sales sequence.
Tell me a bit about your firm. I'll reach out as workspaces and white-label come online, and you'll get a 50% discount on the first three months as a design partner if it's a fit.
These are the actual questions from real conversations. If yours isn't here, the form above is the fastest way to ask.
An isolated bucket per client. Their URL list, their schedule, their branded report. You switch between them in the top nav. Up to 20 included. Need more? Talk to me, the next tier scales further.
Yes. Logo, primary color, optional intro paragraph from your end. The "powered by Bulk URL Checker" line is a small, tasteful footer reference, and it doubles as your referral link if you turn that on.
Proxy rotation across many IPs, per-domain rate limiting so we never hammer a single host, and retry classification that knows the difference between "this URL is genuinely 404" and "they're throttling us, wait and retry through a different IP." This is the unsexy plumbing nobody else has bothered to build.
CSV import auto-detects the URL column from those formats. Ongoing direct integrations (GSC OAuth auto-sync) is roadmap, not shipped. Ask me where it sits in priority.
14 days, full Agency tier, up to 5 client workspaces, no credit card. Once you're in the design-partner cohort it's 50% off the first three months when you upgrade.
