There are two kinds of developers: those who monitor their projects, and those who find out from an angry message on a Sunday.
All of these are free or have a free tier that is enough for a small project.
Uptime Kuma
Self-hosted uptime monitoring with alerts to Telegram, email or almost anything else.
uptime.kuma.petGrafana
Turns metrics from anywhere into dashboards and alerts; the standard for a reason.
grafana.comNetdata
Per-second server monitoring that installs in one command and needs no configuration.
netdata.cloudPlausible
Lightweight, cookieless analytics that will not add a consent banner to your site.
plausible.ioPageSpeed Insights
Real Lighthouse data plus field metrics, which is what Google actually ranks on.
pagespeed.web.devComingURL
Short links with detailed analytics, for measuring which campaign or list actually sent the traffic.
comingurl.comHealthchecks.io
Alerts you when a scheduled job stops running, which is the failure nobody notices.
healthchecks.ioUptime monitoring plus error tracking covers ninety per cent of the incidents in a small project. Set both up before launch, not after the first outage.
