What Is SSLCanary on AppsCyborg and Is It Free?

Updated

SSLCanary is a monitoring tool from AppsCyborg that watches SSL certificate and domain expiry dates for multiple domains and sends plain-language warnings before anything lapses. It is free for up to 5 domains. It sits alongside AppsCyborg's main collection of 79+ online file tools, but it targets a different user: site owners and agencies who need to avoid an expired certificate or domain taking a site offline.

What SSLCanary does

SSLCanary keeps every domain you add in a single list and tracks two expiry events per domain:

  • SSL certificate expiry — the date the certificate stops being valid, after which browsers show security warnings.
  • Domain expiry — the date the registration lapses, after which the domain can stop resolving or be lost.

Instead of leaving you to check dates manually, it sends warnings ahead of time. The alerts are written in plain language rather than raw certificate jargon, so a non-specialist can act on them. Example from the product page: shop.example.com certificate expires in 7 days.

How the alerts reach you

Warnings can be delivered through any of these channels:

Channel Typical use
Email Default, works for solo site owners
Slack Team or agency shared channel
Teams Organizations standardized on Microsoft
Discord Community-run or hobby projects
Telegram Fast mobile notifications

You pick the channel that matches where your team already pays attention, so a warning is unlikely to be missed.

Is it free?

Yes, for small portfolios. SSLCanary is free for 5 domains. The product page does not state pricing for larger domain counts, so if you manage more than five domains, treat the cost for additional domains as unconfirmed and check the site directly.

Who it is for

SSLCanary is aimed at two groups:

  • Site owners running one or a few domains who want a safety net against silent expiry.
  • Agencies and site owners managing many domains who need one consolidated list instead of scattered calendar reminders.

If you only need to convert, compress, or download files, the main AppsCyborg toolset covers that. SSLCanary is the add-on for the operational side of keeping domains and certificates valid.

How to decide whether to use it

Use SSLCanary if any of these apply:

  • You manage up to 5 domains and want free expiry monitoring.
  • You have been caught out by an expired certificate or domain before.
  • Your team lives in Slack, Teams, Discord, or Telegram and would act faster on an alert there.

Skip it, or verify pricing first, if you manage well over 5 domains and need confirmed costs before committing.
