Firebase Remote Config
Firebase Remote Config stores configuration (feature flags, settings, text) in the cloud. Apps fetch config at startup and periodically. Change config without deploying app. Example: toggle dark mode on/off remotely, enable feature for 10% of users, change pricing. Learning: 1 week for basics, 3-4 weeks for advanced A/B testing. Practitioners earn 5-10% premium for running experiments that improve revenue. ROI: instead of releasing 10 app versions, release 1 app + 10 config variations. A/B testing moves from weeks to hours.
What is Firebase Remote Config
Firebase Remote Config is a cloud service for managing app configuration without releasing updates. Store parameters (flags, settings, text) in cloud. Apps fetch config at startup and periodically. Change value, apps see it on next config fetch (no App Store submission needed). Examples: toggle feature on/off, run A/B test (variant A vs B), show promotional text, adjust difficulty level. Remote Config integrates with Firebase Analytics, so you can measure impact of config changes on user behavior (retention, revenue).
