VWO Feature Experimentation lets teams test feature variations—including backend logic, pricing criteria, algorithms, and AI features—and measure their real-world impact. Teams can change experiment configurations without changing the codebase, and machine learning can allocate traffic to a winning variation. A problematic production experiment can be switched off instantly without redeploying or manually toggling it. SmartStats provides Bayesian and Frequentist methods, real-time reports, error and peeking correction, and automatic sample ratio mismatch detection. Supported approaches include A/B testing, multivariate testing, and multi-armed bandits; server-side and mobile experiments and feature rollouts are also listed. Developers can install SDKs and build features, while non-developers configure and test variables in the dashboard. Wingify offers SDKs for 10+ languages and frameworks, REST APIs, an MCP server, and OpenFeature support. Integrations include Amplitude cohort import and campaign-data export, plus two-way real-time data sync with Segment. Pricing is on request, and a 30-day trial is available. The trial includes access to core products, tools, and settings, with a sample-rich playground also offered.
