Charles vs Reqres: What are the differences?

Developers describe Charles as "HTTP proxy / HTTP monitor / Reverse Proxy". Charles is a web proxy (HTTP Proxy / HTTP Monitor) that runs on your own computer. Your web browser (or any other Internet application) is then configured to access the Internet through Charles, and Charles is then able to record and display for you all of the data that is sent and received. On the other hand, Reqres is detailed as "Test your front-end against a real API". A hosted REST-API ready to respond to your AJAX requests.

Charles and Reqres can be categorized as "API" tools.

Some of the features offered by Charles are:

• SSL Proxying – view SSL requests and responses in plain text
• Bandwidth Throttling to simulate slower Internet connections including latency
• AJAX debugging – view XML and JSON requests and responses as a tree or as text

On the other hand, Reqres provides the following key features:

• Reqres does not store any of your data at all
• Fake data
• Real responses
