Overall I'm very impressed with SIGNL4 and am surprised that I'd not heard about it sooner! Used in an I.T support environment, it's been great! Busy looking into using n8n.io with SIGNL4, WhatsApp, Slack, CheckMK, Outlook, Trello etc to make some automations, based on various values in an excel sheet.

A pager app with a reasonable free plan, and push notifications that actually work! (so far anyway) Pro tip: To ensure the free plan's single ringtone is noticed, download an hour long audio track, convert to 64kbps mp3 (to fit in size limit), and use as notification ringtone.

It's an amazing suppliment to any monitoring system. To be able to respond to outages and get notification and phone calls despite missing the alert email makes me seem like a God to my users.

I did not like the way it was laid out. I did not like the notifications process. Kind of felt like it falsely advertised a different service.
