Is Firebase free to use?

Firebase offers a variety of services, and while many of them are available for free, there are limitations and considerations to keep in mind. The free tier, known as the Spark plan, provides access to several core features, including Firebase Authentication, Firebase Realtime Database, and Cloud Firestore, among others. Users can leverage these tools to develop and manage their applications without incurring immediate costs. However, it is important to understand that the free tier has usage limits, which may include restrictions on the number of active users, storage space, database read and write operations, and more. If an application’s usage exceeds the limits set by the free tier, users may need to upgrade to one of the Blaze or Flame paid plans, which operate on a pay-as-you-go model. For detailed information on pricing and limitations, it is advisable to refer to the official Firebase documentation and pricing page available on their website. This will provide the most accurate and up-to-date information regarding costs associated with various Firebase services.
