3 Strategies to Optimize Firebase Remote Config Fetch Usage
With Firebase Remote Config's shift to usage-based billing, developers need strategies to manage fetch requests efficiently.
Firebase Remote Config will switch to a usage-based billing model on September 1, 2026. This change means that Developers Need to be strategic about managing fetch requests to control costs effectively.
Strategy 1: Separate Fetch and Activate Calls
Using fetch() and activate() separately can help optimize fetch usage. By adopting a "fetch for next session" model, developers can manage when configurations are fetched and activated, reducing unnecessary network requests during app usage.
Strategy 2: Set a 24-Hour Minimum Fetch Interval
Implementing a 24-hour minimum fetch interval can significantly reduce the number of fetch requests. For example, if a user opens the app multiple times in a day, the SDK will use the local cache for subsequent launches, reducing the fetch count from potentially 10+ to just one.
Strategy 3: Use Realtime Remote Config for Frequent Updates
For features that require frequent updates, such as toggling feature flags or promoting flash sales, Realtime Remote Config is an ideal solution. It allows developers to attach listeners and receive configuration updates in real-time.
What to Do
Developers should evaluate their current usage patterns and consider implementing these strategies to stay within the no-cost tier, which includes 100,000 daily fetch requests. Existing customers will have a 3 to 5-month grace period to adjust to the new billing model.
