Experiment anywhere in your tech stack

Optimizely Full Stack is more than just mobile experimentation. Go beyond your mobile client and deep into your backend. Test pricing, search algorithms, and more.

Launch with confidence

Reduce the risk of releasing new app versions with phased rollouts. Feature flags, traffic allocation, and remotely configurable variables enable you to test new features and quickly remove or modify the ones that don’t work.

Platform Page mobile Rollout

Update your app in real-time

Modify app UI and functionality in real-time without waiting for App Store or Google Play review.

Platform Page mobile UI

Trunk Club increased lead quality and stylist efficiency with Optimizely

At Trunk Club, mobile is at the forefront of their business. It’s where new customers first tend to interact with the brand and existing customers browse new collections. Because mobile users were often exploring rather than buying, the Trunk Club team experimented with different app mechanics to help separate the window shoppers from serious buyers.
