Choose Optimizely if you test all year and want experiment results computed on your own data warehouse. Choose Wingify if you want to watch heatmaps and recordings beside your tests.
A team testing a whole checkout path needs one experiment held steady across every page. Optimizely runs these multi-page funnel tests. It also puts experiments into mobile apps through its SDKs, which takes a test beyond the web page. The platform suits a team with a steady testing program better than one that runs the occasional experiment.
Large companies with strict access rules get single sign-on, self hosting and a sign-off step before tests go live on Wingify's top tier. Its AI assistant proposes hypotheses, sets up tests and suggests the next experiment. It also sends test data to Google Analytics and other analytics tools. Complex tests and non-standard setups still need developer skills.
Optimizely's users praise phone and email support that fixes simple problems fast. They also report that help after contract signing is slow, with staff turnover and multi-day email waits. Reviewers of Wingify like its visual editor, where non-technical people launch tests without a developer, and find results clear. They report a high price, especially for small businesses or infrequent users. Tracking sometimes disagrees with other tools, and ending a contract or winning a refund is hard.
Optimizely describes a consumer oral care brand selling online, where non-technical teams in marketing, ecommerce and product now launch and validate their own tests. The brand's refill quantity test showed significantly higher conversion and more units per transaction. Wingify tells of a footwear retailer with many British and Irish shops whose experiments targeted the checkout flow and in-store reservation clicks. Checkout completion and the button that drives reservations both improved over their baselines.
