I currently use https://uptimerobot.com/ (free plan) and I'm happy with it. The free plan seems to offer more than yours (50 alert delivery targets & sites watched, same cadence, same metrics, public status pages included in free tier, including RSS, log exporting etc.). To upgrade to pro would also be 10x cheaper for a similar service-level[1,2]. Why should I switch? 1: https://app.webgazer.io/billing 2: https://upt…
Alerting is a basic thing and it is done kind of OK by some others. But true analytics is hard to get, we are still working on providing better reports. As an obvious plus, we provide status pages we produce by the monitoring data collected. This is for not making you depend on another service just for a status page.
Also, we are looking for ways to make WebGazer a complete monitoring and analytics platform. Plans still aren't very clear but server monitoring or client-side analytics are some things we have in mind.
