Check your site is online, and that people can use it

A normal “is it online” check only sees that your site answers. Your site can still be broken: a blank page, a missing sign-up form, or a payment page without its Pay button. We check your site is online every minute on Solo and Starter, every 30 seconds on Pro and Business, and every 5 minutes on Free, and we also open your app the way a visitor does to check the home page and the pages your customers use.

How we check your site is online

Heedza requests your home page every minute on Solo and Starter, every 30 seconds on Pro and Business, and every 5 minutes on Free. This is a plain request, not a full page visit, so it is light on your site.

  • Down alerts. If your site doesn’t answer, shows an error page (such as “page not found” or “server error”), or takes more than 15 seconds, Heedza checks again with a second request. If that fails too, you get an alert (by email, or on paid plans also to Slack, Telegram or a webhook). You get another one when the site is back.
  • Time online (%) and response time for the last 24 hours, 7 days and 30 days, in your dashboard and in your report.
  • https certificate and domain. Heedza reads the date your https certificate (what lets your site open with https) and your domain name run out, and reminds you 14, 7, 3 and 1 day before either does.
  • New version check. Heedza keeps a short record of your home page (its title, description, and script and style files). When it changes, a new version went live, so Heedza runs the full page check soon after (on Free, at most once every 6 hours) and tells you what changed.

Heedza also takes pictures of your pages at phone size (390 px), once a week on Free and once a day on paid plans.

For pages you only want to see online, such as an old landing page, Starter, Pro and Business also have online-only web addresses (20, 50 and 100). They are opened every minute on Starter, every 30 seconds on Pro and Business and get no page checks. They are counted separately from your sites. See pricing.

What we look for on your home page

  • The page opens without an error page.
  • The page shows real text, not a blank screen.

Then Heedza checks your sign-up, log-in and payment pages too.

What it doesn’t do

  • The online check waits for a second failed request before it alerts you. Paid plans check every minute or every 30 seconds. On Free it runs every 5 minutes, so a down alert arrives about 5 to 10 minutes after the site goes down.
  • The online check runs from one location. The page checks run once a day on Free and up to every 15 minutes on Business.
  • Like every Heedza check, it never logs in, fills in forms or pays.

Questions

Should I replace my uptime monitor with Heedza?

On a paid plan you can. Heedza checks your site is online every minute on Solo and Starter, every 30 seconds on Pro and Business, and every 5 minutes on Free, reads when your https certificate and domain run out, and also opens your key pages up to every 15 minutes. Keep another monitor if you need SMS or phone-call alerts, which Heedza doesn’t send.

How do I get a reminder before my domain expires?

Heedza reads when your domain and your https certificate (what lets your site open with https) run out. It reminds you 14, 7, 3 and 1 day before, on every plan, including Free. Renew the domain at the company you bought it from. Most hosts renew the certificate for you.

Does it work if my Supabase project is paused?

Yes. If a paused backend makes your page blank or shows an error, the check fails and you get an alert. See Supabase project paused and your app is down?
