Everything that can take your site down, watched from one URL.
Paste your address and Pingerer sets up the checks that make sense for it. You get one clear alert when something needs you, and nothing when it doesn't.
Uptime monitoring
HTTP, keyword, ping and port checks as often as every 30 seconds, confirmed from more than one region before anyone is woken up.
SSL & domain expiry
Reminders before your SSL certificate or domain registration runs out, plus broken certificate chains and wrong hostnames.
DNS change alerts
Pingerer keeps a copy of your A, AAAA, CNAME, MX, NS and TXT records and tells you when any of them change.
Email deliverability
Plain-English checks of SPF, DKIM and DMARC, so the emails your business sends keep arriving.
Heartbeats
Your cron jobs, backups and workers ping a URL when they finish. If one goes quiet, you get an alert.
Status pages
A public status page that updates itself from your checks, on our address or your own domain.
Alerts & integrations
Email, Slack, Discord, Microsoft Teams, Telegram, ntfy, Pushover, PagerDuty, Opsgenie, webhooks and SMS, with escalation and quiet hours.
API & CLI
A REST API and a command-line tool for sites, monitors, incidents, heartbeats and status updates.
For agencies
Keep each client's sites, alerts and reports separate, and send them a monthly uptime report.
For small businesses
You don't need to know what DNS or DKIM stands for. Pingerer explains every alert in plain English and tells you what usually fixes it, so you can fix it yourself or forward it to whoever looks after your site.
For developers
Keyword and status checks, custom headers, heartbeats for every cron job, signed webhooks, a REST API and a CLI that exits non-zero when something is down.
For agencies
One place for every client's sites, with separate alerts, white-label status pages and a monthly report you can send each client.
