Chaos testing with measured impact

Randomly fail marked scripts at controlled probabilities and quantify their impact on conversion.

Built for reliability

Script-level control.
Add type="text/whyrify" to any script to include it in experiments.
Probabilistic failure.
Requests randomly fail selected scripts at predefined rates.
Automatic analysis.
Whyrify estimates causal impact on conversion using Bayesian models.
Actionable output.
Identify scripts that are critical, degraded, or effectively redundant.
