There actually is the difference.

实际上存在差异。

Socket.io is a Javascript library to manage sockets. In a web-chat example, you create sockets:

Socket.io是一个管理套接字的Javascript库。在Web聊天示例中，您将创建套接字：

1. client(s) to server
2. 客户端到服务器
3. Server to client(s)
4. 服务器到客户端

That is, you control all the end-points, and use socket.io as a tool to communicate between your end-points.

也就是说，您可以控制所有端点，并使用socket.io作为工具在端点之间进行通信。

In contrast, using firebase you only focus around 1 (client to server)

相比之下，使用firebase只关注1（客户端到服务器）

Pros and Cons of using service versus own infrastructure is a different subject, and heavily opinionated.

使用服务与自有基础设施的优点和缺点是一个不同的主题，并且非常自以为是。
