Datadog is the observability platform most stacks already run — hundreds of integrations, best-in-class dashboards, APM, logs, and monitors that include seasonality-aware anomaly detection; ValidAnytime is not a replacement for any of that. It is the trustworthy alarm layer beside it: Datadog's monitors, from fixed thresholds to anomaly detection, carry no stated false-alarm guarantee that survives continuous checking, and ValidAnytime's page tier does — with a certificate on every alarm.
| Capability | ValidAnytime | Datadog |
|---|---|---|
| Valid under continuous monitoring (unlimited peeking) | YesAnytime-valid by construction — Ville's inequality bounds the false-alarm rate at every look at once. | NoFixed thresholds and fixed-n tests inflate false alarms the more often you check. |
| Fleet-wide false-alarm control (online FDR) | YesA false-discovery budget shared across every stream, not per-alert luck. | NoAlerts are configured per-metric; no global bound on false discoveries. |
| Per-alarm statistical certificate | YesEvery alarm ships a guarantee tag and a theorem reference — you can audit why it fired. | NoAn alert tells you a line was crossed, not what its error guarantee is. |
| Prove it on your own history before committing (backtest gate) | YesReplay your past data: a config only ships if it stays quiet on normal history and fires on a real regression. | PartialYou can chart history, but there is no gate that validates a detector's error behaviour before it goes live. |
| Dashboards, APM, logs & integrations | PartialFocused reports on the streams we monitor — not a general observability platform. | YesHundreds of first-party integrations; dashboards, APM, and log management in one product. |
| Seasonality-aware anomaly monitors | PartialWe monitor deviation from a frozen baseline; we do not model daily or weekly seasonality for you. | YesAnomaly and forecast monitors with seasonal algorithms are a genuine strength. |
| A false-alarm rate you can state in advance | YesThe page tier fires inside a stated false-alarm budget that holds however often you check. | NoMonitor sensitivity is tuned by hand; there is no stated error guarantee attached to an alert. |
We are not trying to be a dashboard, a tracer, or a platform. If you need these, reach for the right tool — often alongside ValidAnytime.
A comparison table is claims; behavior is measurable. The honest drift-detector benchmark replays every detector we ship — including the classical control-chart rules most monitoring stacks alert with — against labeled synthetic breaks, and the detector guides explain each rule, where it wins, and where it lies.
Replay your own history through the backtest gate and see whether — and at which point — ValidAnytime would have caught your regression. Free, in minutes.
