Requestly
self-hosted, testing

Requestly is a developer tool designed for frontend developers and Quality Assurance (QA) professionals to enhance the development, testing, and debugging process of web applications. It allows users to intercept and modify network traffic, enabling them to simulate various network conditions, manipulate HTTP/HTTPS requests, and analyze API responses. With Requestly, developers can create custom rules and filters to modify requests and responses, such as adding or removing headers, rewriting URLs, or redirecting traffic. This flexibility helps in debugging issues, testing edge cases, and optimizing performance, ultimately speeding up the development cycle of web applications.
