As a side note, I'll take this opportunity call out the superb Checkmk monitoring system which alerted me to this. I don't see Checkmk mentioned on HN that often...
EDIT: Seems to be fixed. Good job!
What happened to honest businesses with fair, easy to understand pricing?
Well in my case the pricing is very easy to understand. It's free!
I only have < 25 hosts so I self-host the open source version on a $5/month DigitalOcean instance (ironically also reverse proxied through Cloudflare)
So I certainly don't think that's exactly dishonest or unfair. It's been rock solid since I've used it. I don't know how many services you'd need to monitor but the starting prices for Standard and Enterprise seem pretty reasonable to me?
It probably doesn't scale to a very large operation - but then it's not really "cloud first" monitoring akin to something like Prometheus, so perhaps their target audience isn't really likely to have a huge number of services to monitor.
