Optimizely vs LaunchDarkly

Top 7 Reasons Why Leading Companies Choose Optimizely


Free Feature Flags

Optimizely Rollouts offers unlimited free feature flags and rollouts. You can roll out features on any device, test in production before release, and manage all your features in one place.

We believe rolling out features is an essential step on the journey to building a culture of experimentation in product development, so we built Rollouts on an enterprise platform and made it free.
