Question 2

You can select the detection options you need before scanning.

Question 4

What types of websites can be detected?

Accepted Answer

Supports detection of all publicly accessible HTTP/HTTPS websites. For security reasons, we prohibit scanning of internal IP addresses (such as 192.168.x.x, 10.x.x.x, etc.).

Question 5

What export formats are supported for detection reports?

Accepted Answer

Currently supports multiple export formats: JSON (complete data structure, suitable for program processing), Markdown (readable document format), Excel (multi-sheet table data), Word, PDF, etc. You can also directly copy the report content.

Question 6

How long does detection take?

Accepted Answer

Detection time depends on the number of links on the page and the website's response speed. Usually, a page with 50-100 links takes 30 seconds to 2 minutes. We display the detection progress in real-time.

Question 7

Are detection results saved?

Accepted Answer

For free users: Detection results are not saved. All data is only displayed in your browser and is not stored on our servers. For registered users: Task history is saved for 6 months for your reference, and will be automatically cleaned up after expiration to protect your privacy. You can also delete your data at any time in your account. In either case, you can export the report to save it yourself.

Question 8

Why do some links fail to detect?

Accepted Answer

Link detection failures can have various reasons: links are invalid, server response timeout, login required, blocked by firewall, etc. We display specific status codes and error messages to help you determine the cause.

Question 9

What information does SSL certificate detection show?

Accepted Answer

SSL certificate detection shows detailed information such as certificate issuer, validity period, remaining days, signature algorithm, key length, DNS names (SAN), etc., to help you understand the website's security configuration.

Question 10

Is tech stack identification accurate?

Accepted Answer

Tech stack identification is based on HTTP response headers, HTML features, JavaScript libraries and other information, with high accuracy. However, some websites may use custom configurations or hide tech stack information, which may not be fully identified.

Question 11

Are there usage restrictions?

Accepted Answer

To ensure service stability, we limit the number of URLs per scan (usually within 200 links). Basic features can be used unlimited for free. Premium features require registration, and registered users get 10 free premium feature uses per month. Additional usage requires purchasing credits or subscribing to a plan. If your website has many links, we recommend batch detection or contact technical support.

Question 16

What is continuous monitoring? How is it different from one-time scanning?

Accepted Answer

One-time scanning generates a detailed report at a single point in time. Continuous monitoring runs checks automatically on a schedule (every 5/10/15/30 minutes) to track uptime, SSL certificate expiry, domain registration expiry, page screenshots, and broken links — alerting you the moment issues are detected. Monitoring also provides SLA reports (uptime %, response time, incidents) and shareable public status pages.

Question 17

How many monitor sites can I create?

Accepted Answer

Monitor site limits depend on your subscription plan: free (unregistered) users get 2 sites, Basic plan users get 10 sites, Pro plan users get 50 sites, and Enterprise plan users get 500 sites. Each site supports up to 5 check types (uptime, SSL, domain, broken links, screenshot). You can upgrade your plan anytime to increase the limit.

Question 18

How do alert notifications work?

Accepted Answer

When a monitor detects a status change (e.g., site goes down, SSL certificate nearing expiry, domain about to expire), an alert is created and an email notification is sent. Alerts are deduplicated within a 1-hour window to avoid spam. You can view all alerts (with read/unread status) on the monitoring alerts page.

Question 19

What are public status pages?

Accepted Answer

Each monitor task can generate a secure public status page with an unguessable token URL. You can share this link with clients or stakeholders to show real-time uptime status, SLA data, and incident history — without requiring them to log in.
