for my homelab i went with free tier of hetrixtools. it monitors uptime from different locations and has a number of alert options (email, webhook, etc.). free tier was enough for my small needs. as a bonus it also alerts for certificates nearing expiry, smtp monitor, heartbeat. pretty good for hobbyists.
