Monitoring Tiny Web Services

Uptime Kuma

Currently got the cheapest VPS that I could (in my case from Time4VPS, some others might prefer Hetzner, or Scaleway Stardust instances), setup Uptime Kuma on it (https://github.com/louislam/uptime-kuma), now have checks every 5 minutes against 30+ URLs (could easily do each minute, but don't need that sort of resolution yet). It's integrated with Mattermost currently, seems to work pretty well. Could also set it up on another VPS, for example on Hetzner (which also has excellent pricing), could also integrate another alerting method such as sending e-mails, or anything else that's supported out of the box: https://github.com/louislam/uptime-kuma/issues/284 Oh, also Zabbix for the servers themselves. Honestly, if things are as simple to setup as nowadays and you have about 50 EUR per year per node that you want (1 is usually enough, 2 is better from a redundancy standpoint, since then it becomes feasible to monitor the monitoring, others might go for 3 nodes for important things etc.), you don't even need to look for cloud services or complex systems out there. Of course, if someone knows of some affordable options for cloud services, feel free to share! I briefly checked the prices for a few and most of them are more expensive than just getting a VPS, setting up sshd to only use key based auth, throwing Let's Encrypt in front of the web UI (or maybe additional auth, or making it accessible only through VPN, whatever you want), adding fail2ban and unattended updates, and doing some other basic configuration that you probably have automated anyways.

Cronitor

Healthchecks is a great service! Not sure if you tried it too but https://cronitor.io/ supports complex alerting rules like the one you describe. As a bonus, you can also create uptime checks and status pages under the same roof. Full-disclosure: I work at Cronitor.

k3s

One reason this is not feasible is that K8s doesn't really support secure multitenancy, so for every tenant, you'll need to spin up an entire K8s control plane, which includes a database and several services - this is what's driving the cluster fees. Keep in mind that customers also expect managed K8s to be highly available, so this cost is also going into things like replicating data, setting up load balancers, etc... Compare this to a serverless offering that is multitenant by design, the overhead cost of an extra user is basically zero, which is why they don't charge you a fee like this. IMO if you're a hobbyist interested in K8s, your best way to go is to install K3s, which is a lightweight, API compatible K8s alternative that runs on a single node. It's pretty nice if you don't care about fault tolerance or High Availability. https://k3s.io/.
