I use pushover.net for all of my lightweight notifications - it's simple, reliable, cheap and very good so fits well with updown.io :) At its simplest, integration takes the form of an API call with a couple of tokens and a customised message. https://pushover.net/faq#technical-ips

Updown.io is one of the best services I have EVER interacted with! Thank you!

Per status page: 1) Clicking on the service now open page on updown, let us switch that on/off, if we don't want that 2) Let us switch on/off the display of check frequency General: And also, let us clear the history of 1 or multiple checks.

Ability to monitor periodic tasks with a simple HTTP call (like https://github.com/healthchecks/healthchecks , https://deadmanssnitch.com/ or https://cronitor.io/ ) ex: curl https://updn.io/9jNKL24

How about having a dark theme? I find it a bit aggressive to the eyes after few minutes. Having a toggle button and choose between original or website in a dark theme would be amazing!

It would be great to have Signal ( https://signal.org ) as an Alert Channel. Other services support this so it might be possible (e.g. https://healthchecks.io/ ). I find this very convenient as Signal is very popular here (and also cheaper than SMS I suppose).

I think a custom logo has been suggested before in a comment ( https://updown.canny.io/general/p/custom-css-for-public-status-pagess ), just wanted to raise it a suggestion now
