What pingdan is
pingdan is a free web service for scheduled HTTP endpoint monitoring. Each monitor checks response assertions such as status codes, response time, headers, response bodies, and JSON paths, then alerts when checks fail. Intervals range from 1 minute to 7 days, and a configurable number of consecutive failures determines when a monitor changes to down. Charts show 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 certificate checks are automatic, with expiry warnings beginning at 15 days or fewer remaining. The Free plan costs nothing and includes unlimited monitors, 1-minute intervals, all assertion types and alert integrations, full history, and latency percentiles. Setup is said to take under a minute without agents or configuration files. TLS, bcrypt password hashing, and signed expiring sessions are listed security measures.
