Firebase Spark no-cost app development plan

Firebase's Spark plan is the no-cost option for developers who want to build and test apps without adding a payment method. Google currently describes Spark as a no-cost plan and says no payment method is needed. It includes no-cost Firebase products such as Analytics, A/B Testing, App Check, App Distribution, Cloud Messaging, Crashlytics, In-App Messaging, Performance Monitoring, and Remote Config. Several infrastructure products also have limited free allowances, with product-specific quotas shown on the official pricing page. Firebase notes that Spark projects can be shut off for the remainder of a calendar month when certain no-cost resource limits are exceeded, rather than automatically billing overages. Use the official pricing page to review the current quota for the exact Firebase product you plan to use before deploying a production workload.
