When it comes to developer tools, there are many options available to choose from. Three popular options for web debugging and proxying are Proxytool, Fiddler and Charles. All three tools are useable for proxying and monitoring requests and responses, but they have different features and capabilities. In this blog post, we will compare Proxytool, Fiddler, and Charles and explore how each tool can support your development process.

What is Proxytool

Proxytool is a cloud-based middleware application that allows users to forward requests from a client to a backend server and modify the requests or responses as they pass through the proxy using predefined rules. It can be used for adding additional functionality or troubleshooting issues, but it is not meant to be used for adding security measures. It can modify anything in a request or response but will not modify the backend server or the client application itself. It is best suitable for development and testing.

What is Fiddler

Fiddler is a popular web debugging proxy tool that allows developers to view and modify requests and responses. It also has features such as SSL proxying, bandwidth throttling, and request/response editing. It also includes a powerful event-based scripting subsystem, and can be extended using any .NET language. Fiddler is suitable for development, testing, and production debugging.

What is Charles

Charles is another popular web debugging proxy tool that allows developers to view and modify requests and responses. It also has features such as SSL proxying, bandwidth throttling, and request/response editing. It also allows developers to debug and test mobile applications, and it is possible to record and replay web sessions. Charles is suitable for development, testing, and production debugging.

Comparing the Features

When comparing the features of Proxytool, Fiddler, and Charles, all three tools allow developers to forward and modify requests and responses, but they have different focuses and capabilities.

Fiddler and Charles are more intended for request capturing and monitoring. They run locally on your machine, and you can debug local traffic. It is great for finding request and response content that happened on your machine. But as it captures all communication running in your browser, it's harder to find relevant data. It's easy to just start it up and look into any communication happening on your machine.

You can also add Fiddler to your .NET project, so you can even deploy it to your system.

Proxytool, on the other hand, is a cloud-based tool. You add the proxy URL to your app, and it forwards only the relevant requests. The additional benefit compared to the other tools is that it can be used easily in mobile apps, or even in IoT devices, as it's not directly integrated into the app itself. The logs and modification rules are easily accessible to anyone using it.

Proxytool is more aimed at mocking the requests and responses so your app and your backend will get complete responses like everything is already done. Monitoring data is secondary and more aimed at centralization, so each side can easily access the logs to see what happened.

In short, if you are looking for a tool with granular control and advanced features, you can go with Fiddler and Charles, but if you are looking for a tool to add functionality or troubleshoot issues, you may find Proxytool to be a better fit.

Collaboration and Accessibility

Another key difference between the three tools is their approach to collaboration and accessibility. Proxytool is a cloud-based application, which means that it can be accessed from anywhere and can be used by multiple developers at the same time. Fiddler and Charles, on the other hand, are standalone applications that can be installed on a developer's local machine. This means that they are not as easily accessible to other developers and that it can be difficult to collaborate with others.

Debugging and Troubleshooting

When it comes to debugging and troubleshooting, all three tools have their strengths and weaknesses. Proxytool allows developers to modify requests and responses on the fly using predefined rules, which can be useful for troubleshooting issues that are difficult to reproduce. Fiddler and Charles have more advanced features, such as SSL proxying and bandwidth throttling, and they also include a request/response editing feature that can be useful for debugging and troubleshooting.

Ease of Use

In terms of ease of use, all three tools have different approaches. Proxytool has a user-friendly interface and easy-to-use predefined rules, while Fiddler and Charles have a more advanced feature set and may have a steeper learning curve.

Conclusion

In conclusion, all three tools, Proxytool, Fiddler, and Charles, are valuable tools for developers but have different features and capabilities.

Proxytool is a cloud-based middleware application that allows developers to forward requests and modify them easily. It helps add additional functionality to your app while developing or troubleshooting issues.

Fiddler and Charles are popular web debugging proxy tools that allow developers to view and modify requests and responses. They also have features such as SSL proxying and bandwidth throttling. Both Fiddler and Charles are suitable for development and testing.

The choice of which one to use will depend on the project's specific needs, the level of granularity required, and the ease of use.
