A Detailed Comparison of FluxAuth and AuthGuard

Published at 08/05/2023, 23:16

In this article, we compare two authentication services: FluxAuth and AuthGuard. To help you make the best decision for your project, we have compared these two solutions in terms of features, usability, and pricing.

Documentation and Code Examples

When it comes to documentation, FluxAuth excels by providing clear and concise information with code examples. This makes it easy for developers to integrate FluxAuth into their applications. On the other hand, AuthGuard only offers code examples without any proper documentation, which might make it challenging for some developers to work with.

FluxAuth has natively written SDKs for several languages, including C#, C++, Python, Go, JavaScript, and PHP. AuthGuard provides examples for C#, C++, Python, and PHP. However, it’s worth noting that AuthGuard locks their C++ code example behind their paid plan, while FluxAuth offers all their documentation for free.

Pricing Models

FluxAuth follows a pay-as-you-go model, ensuring that you only pay for what you need without any risk. This flexible pricing model is ideal for projects with varying requirements. In contrast, AuthGuard charges a one-time payment of $15 for lifetime access. While this might seem like a good deal initially, it’s important to consider the sustainability of a service that requires infrastructure to run, as lifetime access could be a risk in the long run.

Variable Support

FluxAuth supports variables in various formats, including strings, bools, and files. This increased flexibility allows developers to store and use different types of data in their authentication processes. AuthGuard, on the other hand, supports only strings, which might be limiting for some applications.

System Integration

When it comes to integration, FluxAuth offers a streamlined license-only system, making the implementation process simple and straightforward. AuthGuard utilizes a user and license system, which can complicate the integration as account registration and login need to be implemented.

Server Performance

Another aspect to consider is server performance. FluxAuth is known for its fast and reliable servers, ensuring that your authentication processes run smoothly. AuthGuard, however, has been reported to have slow servers, which could affect the overall performance of your application.


In summary, FluxAuth stands out as a more robust and user-friendly authentication service compared to AuthGuard. With clear documentation, flexible pricing, better variable support, and faster servers, FluxAuth is a smart choice for developers seeking a reliable authentication solution.
