Everything you need to know about our bulk URL checker
A bulk URL checker validates thousands of URLs simultaneously. Upload a CSV file with up to 75,000 URLs, and we check status codes, redirects, response times, and more — all in the cloud, with no software to install.
We use a simple credit-based system: 1 credit = 1 URL check. Buy a credit package when you need it — no subscription, no recurring charges. Credits never expire. Every new account starts with 300 free checks, no credit card required.
Our system uses intelligent proxy rotation and automatic retry logic to handle common rate limit scenarios. While we can't guarantee all rate limits can be bypassed, our system prioritizes quality and domain respect — ensuring reliable results for the checks that complete.
For each URL: HTTP status code (200, 404, etc.), full redirect chain, response time in milliseconds, final destination URL, and timestamps. Export everything to CSV or JSON. The dashboard lets you filter by status code and search specific URLs.
Screaming Frog is a desktop crawler. We are a cloud-based bulk checker — no installation, no babysitting. Key differences: runs unattended with email notifications, built-in proxy rotation for rate limits, dashboard analytics, monthly subscriptions from $9 (or $9.99 for 10K credits one-off) vs £149/year, and up to 75,000 URLs per batch.
Yes. All paid plans include scheduled checks. Starter ($9/mo) gives you 1 weekly schedule; Pro ($29/mo) gives 5 daily schedules with email diff alerts; Agency ($99/mo) gives 50 daily schedules with Slack and webhook diff alerts. Daily is the cadence floor across all plans so we don't look like aggressive scrapers to third-party sites.
300 free URL checks on every new account. Subscriptions (recurring monthly URL pool): Starter $9/mo (15K), Pro $29/mo (50K), Agency $99/mo (200K). One-off credit packs are still available after sign-in for occasional top-ups: 10K ($9.99), 30K ($23.99), 75K ($49.99). Subscriptions cost less per URL at every tier.
