Gun vs Pusher: What are the differences?
Performance: Gun is a decentralized, peer-to-peer database that can handle a higher volume of concurrent users compared to Pusher, which is a centralized service. This makes Gun more suitable for applications that require scalability and high performance.
Cost: Pusher is a paid service that offers various pricing plans based on usage and features, while Gun is an open-source, free-to-use database solution. This makes Gun a more cost-effective option for developers looking to minimize their expenses.
Data Storage: Gun stores data in a distributed manner across multiple peer nodes, providing data redundancy and better fault tolerance. In contrast, Pusher stores data in a centralized server, which may introduce a single point of failure.
Customization: Gun allows for extensive customization and control over data handling, synchronization, and conflict resolution through its decentralized architecture. Pusher, on the other hand, offers a more simplified and managed approach, which can be easier to set up but may limit customization options.
Integration: Pusher provides ready-to-use libraries and APIs for popular programming languages and frameworks, making it easier to integrate with existing applications. Gun may require more effort and developer expertise to integrate effectively due to its decentralized nature.
Real-time Features: Pusher offers advanced features such as presence channels, webhooks, and user authentication mechanisms out of the box, making it suitable for complex real-time applications. Gun focuses more on the data synchronization aspect and may require additional development effort to implement similar real-time features.
In Summary, Gun and Pusher differ in terms of performance, cost, data storage, customization, integration, and real-time features.
I am building an IoT application that will utilize connected air quality sensors to provide real-time indoor air quality in offices. I want to be able to share this data with a few different databases, etc.
Wondering if anyone has any advice on which real-time streaming API would be best for this sort of application, or even how I should think about it?
For IoT, we support MQTT along with websockets and SSE. The pattern you're suggesting that involves harvesting data from devices and soaking into a database is easy to achieve with one of the Ably integrations (Serverless functions/webhook) . Here are some tutorials to do things like this: https://ably.com/tutorials/reactor-event-zapier#step2-mqtt-ably
We use Pusher at www.justlearn.com. It works fine. When you reach more users, Pusher gets expensive. We use Pusher for live chat between users. Their software is easy to use. We have had issues with auth on Pusher.
