About CleverUptime

The server monitoring tool we wished we'd had — so we built it.

CleverUptime is smart monitoring for Linux servers. It watches the whole machine, sets itself up, and when something goes wrong it tells you the cause and the fix — not just a flashing red light. It keeps an eye on servers, uptime, domains, page speed, ports, and SSL certificates, and behind every alert sits a knowledge base that explains the why. If you want the full tour, that's what how it works and the features page are for.

But the honest reason it works the way it does isn't a feature list. It's a confession.

Who Builds It

CleverUptime is built by arndt.ai GmbH in Munich, Germany, started in 2023. We're not a faceless monitoring vendor — we're developers who have spent two decades setting up, running, and occasionally setting fire to Linux servers, reaching for the docs at 2 a.m. like everyone else. We run CleverUptime on our own machines every single day, so when something here feels off, we're usually the first to notice. We've earned that instinct the hard way.

Things We've Broken

We didn't design CleverUptime from theory. We reverse-engineered it from our own worst mornings. A partial, dignity-free list:

  • Left a database listening to the entire internet, no firewall, for longer than we'd like to put in writing.
  • Restarted the wrong server — turns out trusting your memory when three boxes all answer to localhost is a poor identity strategy.
  • Tuned MySQL so lovingly it devoured every byte of RAM and introduced us, personally, to the OOM killer.
  • Let a disk fill to 100% and watched a perfectly healthy server quietly seize up over nothing but housekeeping.
  • Saw a SMART warning, thought “I'll deal with that later,” and learned that disks do not wait for later.
  • Discovered — mid-incident, naturally — that the backups had been silently failing for weeks.
  • Ran a RAID array degraded for a fortnight because nothing thought to mention the first disk had died.
  • Let an SSL certificate expire and took our own checkout offline, in front of real customers, for a very long few minutes.

Every one of those is now something CleverUptime watches for — because we never want that morning again, and we'd rather you skipped it entirely. Got one of your own to add, or any feedback at all? We genuinely want to hear it: get in touch.

The fastest way to get what we're about is to point it at your own server.
