Firebase Vs Firestore: Key Differences
The table below highlights how Firebase and Firestore have differing data modeling, querying, and scaling capabilities:
Here is a detailed explanation of Firebase vs Firestore comparative features:
Service Type
Firebase offers you a comprehensive set of tools and services for building and running applications. These services include app hosting, cloud functions, Genkits, app distribution, remote configuration, and more. You can also use the Firebase Realtime database to store data, which is suitable for small-scale applications.
Whereas, Firestore is a NoSQL database that is a part of the Firebase product spectrum. You can utilize Firestore to store, query, and synchronize data for web and mobile applications. Firestore focuses more on scalability, flexibility, and data management, making it suitable for large-scale applications.
Data Modeling
In Firebase Realtime Database, you can store data in a single large JSON tree, where all of your data is represented in a hierarchical structure. However, as the data grows and becomes more complex, querying and organizing data becomes a bit challenging.
In contrast, Firestore provides a more flexible data model. It uses a collection of documents to store the data. These documents are very similar to JSON objects. Each document contains a key-value pair and is grouped together within a collection, making it easy to query, manage, and scale data.
Scalability
You can use the Realtime Firebase database to scale around 200,000 concurrent connections and 1000 writes per second. To scale beyond this limit, you can split your resources among multiple real-time database instances to balance the load.
Firestore is comparatively more scalable than Firebase. It provides automatic scaling. You can use Firestore to scale up to one million concurrent connections and 10 thousand writes per second.
Reliability and Performance
Firebase provides low latency, lower than Firestore, with 10 ms for response and real-time updates. These features make it ideal for applications that require instant data synchronization among multiple devices.
In comparison to Firebase, Firestore is a more robust solution when it comes to reliability and performance. It supports multi-region replication, ensuring high data availability, and can handle large and complex datasets more efficiently than Firebase.
Security
Firebase supports GDPR and CCPA to protect personal and business data. It facilitates App Check for data integrity and validation and Firebase Authentication to prevent unauthorized access. Other than this, Firebase monitoring allows you to calculate the number of unique Firebase installations that access resources to inspect access patterns.
Firestore, on the other hand, provides security through features like IAM, server-side encryption, Firebase security rules, and configuration language. You can implement security rules for access control and data validation. These rules can be customized according to the data model you create. Besides this, the Firestore uses server-side encryption to automatically encrypt data before writing it to disk and decrypt it when read by an authorized user.
Pricing and Cost Consideration: Firestore vs Firebase
Firestore and Firebase both offer you two types of pricing models. The Free-tier model enables you to start working with your database and application at no cost for a certain period of time. For the pay-as-you-go model Firebase and Firestore charge you based on the services you want to acquire and operations you want to perform.
When you are using Firestore, you are charged for:
- The number of documents you want to read, write or delete.
- The number of index entries used to satisfy a query
