About updown.io
updown.io is a website monitoring service that checks HTTP, TCP, ICMP and other endpoints from at least two locations. It is built to be simple, with clear alerts and a pricing model that charges only for the checks you run.
What it does
updown.io checks your endpoints at intervals from 15 seconds to one hour and sends an alert when a check fails. A downtime is confirmed from a second location before you are notified. It also watches TLS certificates and domain expiry, and it can monitor scheduled tasks that send a ping.
Key features
- HTTP, TCP, ICMP and other check types
- Pulse and cron monitoring for scheduled jobs
- Dual stack IPv4 and IPv6 checks
- Text search to confirm page content
- Alerts by email, webhook, Slack, Teams and more
Who it's for
Developers, small teams and site owners who want reliable uptime checks without a large dashboard. The REST API and webhooks suit teams that want to connect monitoring to their own tools.
Pricing and good to know
You buy credits and pay only for the checks you run, with no commitment. Larger credit packs cost less per check. Payment is accepted by card, PayPal, SEPA transfer and several cryptocurrencies.
