Why Hexadecimal?

There are dozens of alternatives on the market. What makes you special?

Debug problems faster

When it hits the fan, you want to spend as little time as possible in identifying the problem. While run-of-the-mill monitoring software can notify you that your website is down, they might not tell you what went wrong, what might have caused it, and how to troubleshoot the problem. Basically, you're left in the dark. Not with Hexadecimal!

Minimum false positives

If your website appears to be down, it will be checked from at least 4 different locations throughout the world. The website is only marked as down if the majority of servers can agree on that. This alone rules out a lot of false positives. Your attention, sleep, and inbox are treated with the utmost respect!

Powerful alerting

Hexadecimal has rich, actionable notifications. But what good are they if they are sent at the wrong time? Or worse, sent only once? You can set up global or local notifications. You can choose when to send the first notification (so that you won't be bothered by very short downtimes). Downtime notifications will be sent with exponential backoff, making sure you won't miss them.

Personal support

You won't be redirected from one support ticket to another while told to wait 5 business days. You will be getting support from the founder who has built the entire thing himself. Whatever your problem might be, you will be given the attention you deserve.

Certificate expiry checks

You have probably automated the certificate renewal process, but it never hurts to keep an extra pair of proverbial eyes on your SSL/TLS certificates. Less stress for engineers, fewer tickets for support folks.

Dark mode

If your operating system supports dark mode, the interface will automatically darken the colors. Pure white background looks jarring in low-light environments. Easier on your eyes, good for your sleep.


Getting out should be as easy as getting in, that's why you can permanently delete all your data with a click of a button. You won't be pestered with obnoxious popups trying to harvest your email. If you aren't satisfied with the service within 30 days, you get your money back, no questions asked.

Indie business

Hexadecimal is a small and independent business run by someone who cares. There are no investors to be beholden to, no growth targets to hit, and no pressure to exit in the next few years. You pay money for the service, and in return, get peace of mind knowing that your websites are up and running.

No tracking

There are no advertising beacons, tracking pixels, or other voodoo on this website. Ditto for all emails sent by Hexadecimal. You won't see annoying cookie notices around here, because cookies are used for what they were intended to, instead of snooping on you. You are safe from the prying eyes of Big Tech.
