Firebase vs MongoDB Stitch: What are the differences?

Firebase: The Realtime App Platform. Firebase is a cloud service designed to power real-time, collaborative applications. Simply add the Firebase library to your application to gain access to a shared data structure; any changes you make to that data are automatically synchronized with the Firebase cloud and with other clients within milliseconds; MongoDB Stitch: Backend as a Service for web and mobile applications. MongoDB Stitch lets developers focus on building applications rather than on managing data manipulation code, service integration, or backend infrastructure. Stitch lets you focus on building the app users want, not on writing boilerplate backend logic.

Firebase belongs to "Realtime Backend / API" category of the tech stack, while MongoDB Stitch can be primarily classified under "Platform as a Service".

Some of the features offered by Firebase are:

• Add the Firebase library to your app and get access to a shared data structure. Any changes made to that data are automatically synchronized with the Firebase cloud and with other clients within milliseconds.
• Firebase apps can be written entirely with client-side code, update in real-time out-of-the-box, interoperate well with existing services, scale automatically, and provide strong data security.
• Data Accessibility- Data is stored as JSON in Firebase. Every piece of data has its own URL which can be used in Firebase's client libraries and as a REST endpoint. These URLs can also be entered into a browser to view the data and watch it update in real-time.

On the other hand, MongoDB Stitch provides the following key features:

• REST API to MongoDB Atlas
• Declarative data access controls
• Service integrations (AWS S3, Twilio...)
