📅
Scheduled Checks

Auto-crawl daily, weekly, or monthly. Register up to 20 sites — set it once, then forget it.

📧
Conditional Email Alerts New

Notify only when new errors appear — or on every run. Signal, not noise.

📊
Diff vs Previous Run

New, continuing, and resolved errors sorted automatically — see the impact of your fixes at a glance.

🔁
Re-check Failed URLs New

After fixing, re-test just the broken URLs in one click — no need to crawl the whole site again.

Error Status Tracking

Mark each URL fixed, in-progress, or on hold, with your own notes. Nothing slips through.

🔐
Auth & Multi-Site Support

Basic auth, cookies, custom headers — saved as reusable Crawl Configs across all your sites.

🌙
Runs in the Background

Crawls run server-side. Close the browser — it keeps going, and auto-resumes after our maintenance restarts.

📥
CSV Export & Error Details

Download error lists as CSV — with the reason (404, timeout, SSL…), status code, and the exact linking page.

🛑
Safety Stop Options

Auto-stop after a page count, error count, or time limit. Unexpectedly huge sites stay under control.
