With Firebase Remote Config, you can change the behavior and appearance of your app on the fly from the Firebase console, and then track performance in Google Analytics for Firebase. Customize by audience segment, release new content, and split test to validate improvements, all without waiting for app store approval.
Customize everything about your app
Make changes to your app's default behavior and appearance by changing server-side parameter values. For example, you could change your app's color theme to match a seasonal promotion or change the start date of a sale with no need to publish an app update.
Tailor your app to different audiences
Provide a different app experience to different segments of your user base. You can segment by user property, app version, operating system, language, country, and by any custom audience you can define in Firebase Analytics.
Run A/B experiments easily
Remote Config works with A/B Testing so you can set up and run experiments to test changes to your app. Want to tweak your onboarding flow? Or get insight into how a new feature will impact engagement? Use Remote Config with A/B Testing to understand which changes are worth rolling out widely.
A/B testing was built in partnership with Google Optimize, an A/B testing and personalization tool for the web.
