अक्सर पूछे जाने वाले प्रश्न

Are the checker tools really free?

Yes. Every tool on this site, including the DNS, SSL, WHOIS, speed and security checkers, is free to use without an account. They are rate limited to keep the service fast for everyone.

What do I get on the free monitoring plan?

Three monitors checked every 5 minutes or slower, email and webhook alerts, SSL and domain expiry warnings, keyword and JSON checks, maintenance windows, a public status page, uptime badges and a monthly report.

When will the Pro plan launch?

We have not set a date or a price yet, and we would rather say so than invent one. Pro will add more monitors, 1-minute checks, SMS alerts, custom-domain status pages and multi-region checks. When it launches, the free plan stays.

Is there a free API?

Yes. Create a key at API docs. The free key allows 200 requests per day, which resets at 00:00 UTC.

Will you charge me automatically?

No. There is nothing to charge today. When paid plans launch they will be opt-in, with their own terms.

Do you show ads?

The site may show clearly labelled ads in future to cover running costs. Ads never appear inside tool results or alerts. See our संपादकीय नीति.
