Best value of any tool I've ever used. It does literally everything you asked. I didn't even know it checked SSL expiry till it pinged me.

Or use a service like https://updown.io/ (I host my status page there).

I noticed on my server that the latest version of certbot (CLI tool for LetsEncrypt) broke my automatic renewal script.
This happened after the snap did an unattended update.
I had to replace the --webroot parameter with --nginx
Luckily I had monitoring [1] in place to alert me beforehand

updown.io https://updown.io/ has a pretty generous free tier and (in addition to checking if your service is up) sends you a warning when a cert is expiring within 14 days

I've started using `serveo.net` to monitor my internet uptime (Raspberry Pi with a simple webserver, [updown.io](https://updown.io) to request it via [serveo.net](https://serveo.net)) but they were unavailable/offline for ~4 days within the last 10 days.

I run https://updown.io since 2012, a website monitoring service I created. I'm working about 5-10 hours per week on it. It makes about $6,000 per month and is still growing linearly. I also keep a full-time job alongside for now as an engineering manager. The key for me is to take time, make something useful, delight your clients, and don't try to become uber or airbnb.

I will answer myself: https://updown.io
I think I will use it in https://apility.io, a service that competes at some point with this.

updown.io also has a relatively new feature called cron monitoring[0] that allows you to regularly check in to signal success. If there has been no check-in in a configured time it will alert you. For backups you could add a simple curl somewhere into your backup process to do just that.

I like monitored cgi shell script endpoints a lot, e.g. the one behind https://updown.io/44q5 is https://codeberg.org/mro/internet-radio-recorder/src/branch/master/pag…

In case anyone finds this later: I've searched more, by looking at demo pages of popular status monitoring tools hoping to find GitHub, and I've found one such demo: https://updown.io/d043

Seeing the same, thanks. Looks like updown.io is having an issue with TLS. It also lives here if you wanted to take a look: https://updown.io/fj8q

In a busy market, distribution is king. It's hard to get your name out there.
Speaking of unknown players in this space, check out the wonderfully minimalistic updown.io. It's much cheaper than SP and really is quite good.
