VWO Feature Experimentation
Delhi, India and Paris, France
What it is
VWO Feature Experimentation tests versions of product features, including backend logic, pricing criteria, algorithms, and AI features, against real-world impact. Teams can create variations and change experiment settings without altering their codebase. Machine learning can direct traffic toward a winning variation, while a problematic production experiment can be switched off immediately without redeployment. SmartStats provides Bayesian and Frequentist methods, real-time reports, error and peeking correction, and automatic sample-ratio-mismatch detection. Supported methods include A/B tests, multivariate tests, and multi-armed bandits, with server-side experiments, mobile experiments, and feature rollouts available. Developers install SDKs and build features; non-developers configure and test variables from the dashboard. Wingify offers SDKs for more than 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 synchronization with Segment. The service supports Android, iOS, web, and API use. A 30-day trial is available; paid Growth, Pro, and Enterprise plans have pricing by request. Wingify was founded in 2009 and is headquartered in Delhi and Paris.
