Know the moment your website goes down
SignalDocks checks your URLs every minute, alerts your team instantly, and keeps a full history of uptime and response times.
Free plan available · No credit card required
1-minute checks
Catch outages in seconds, not hours. Paid plans check as often as every minute — far faster than the standard 5-minute free tier.
Instant multi-channel alerts
Get notified via Email, Slack, Telegram, or webhook the moment a check fails. Recovery alerts are sent automatically too.
90-day uptime history
View response time charts, uptime percentages, and check-by-check logs to understand your service's reliability over time.
