What is relayd?
relayd is an open-source command-line interface (CLI) tool designed to help developers replay HTTP requests. It captures incoming HTTP requests and allows users to replay them to a different target, making it ideal for testing, debugging, and development workflows. This tool simplifies the process of reproducing issues, testing API changes, and validating integrations by providing a straightforward way to resend previously captured requests.
It's particularly useful for developers, QA engineers, and anyone working with APIs who needs to simulate network traffic or test how their applications respond to specific HTTP interactions. By enabling easy request replaying, relayd helps accelerate the development cycle, improve testing efficiency, and ensure the reliability of web services and applications.
