Why pingdan

Everything you need to trust your uptime

Monitoring built for engineers who want signal, not noise.

Deep assertions

Go beyond status codes. Validate headers, response body, JSON paths and response time on every check.

Response-time charts

Per-endpoint bar charts, p50/p95 latency, and uptime history so you spot regressions early.

1-minute checks

Fixed, predictable intervals from 1 to 8 minutes. Know about incidents fast.

Instant alerts

Email and Telegram notifications the moment an endpoint goes down — and again when it recovers.

Failure thresholds

Avoid noise. Only alert after N consecutive failures, with full per-check failure detail.

Set up in a minute

Paste a URL, pick what makes a check pass, and you're monitoring. No agents, no config files.
