Chaos testing with measured impact

Built for reliability

Quantify system behavior under failure

Validate frontend third-party scripts and dependencies by observing real user conversion impact under controlled fault injection.

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.
