Apollo vs Firebase: What are the differences?
Developers describe Apollo as "GraphQL server for Express, Connect, Hapi, Koa and more". Build a universal GraphQL API on top of your existing REST APIs, so you can ship new application features fast without waiting on backend changes. On the other hand, Firebase is detailed as "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.
Apollo can be classified as a tool in the "Platform as a Service" category, while Firebase is grouped under "Realtime Backend / API".
"From the creators of Meteor" is the top reason why over 8 developers like Apollo, while over 317 developers mention "Realtime backend made easy" as the leading cause for choosing Firebase.
Apollo is an open source tool with 7.4K GitHub stars and 911 GitHub forks. Here's a link to Apollo's open source repository on GitHub.
According to the StackShare community, Firebase has a broader approval, being mentioned in 838 company stacks & 957 developers stacks; compared to Apollo, which is listed in 123 company stacks and 121 developer stacks.
