Bayesian results, not p-hacking
Real-time probabilities — "82 % chance Variant B wins by ≥ 8 %." No more screwed-up significance thresholds.
Multivariate by default
Test 3 headlines × 2 heroes × 4 CTAs simultaneously. Bandit allocation routes traffic to winners automatically.
Segment-aware reporting
Variant B wins overall — but loses on mobile. You see the cross-tab without writing SQL.
Goal anywhere, not just clicks
Track downstream events (signup → activation → revenue). Optimize for what matters, not vanity micro-conversions.
One-click ship the winner
Promote the winning variant. It rolls out to 100 % of traffic — and the change lives in your code repo.
Frequently asked
