What pingdan is

pingdan is a free web service for scheduled HTTP endpoint monitoring. Each monitor checks assertions against responses, covering status codes, response time, headers, response bodies, and JSON paths. Intervals range from one minute to seven days, and a configurable number of consecutive failures determines when a monitor becomes down. The dashboard presents response-time bars, uptime timelines, and average, p50, p95, minimum, and maximum latency. Alert channels include email, Telegram, Slack, Discord, Microsoft Teams, generic webhooks, PagerDuty, ntfy, Pushover, Twilio SMS, and Opsgenie. HTTPS endpoints receive automatic certificate checks, with warnings beginning at 15 days or fewer before expiry. The maker says setup takes under a minute and needs no agents or configuration files. The free plan costs nothing and includes unlimited monitors, all assertion types and integrations, full history, and latency percentiles.
