24 alternatives to A simple echo server for testing HTTP clients

I have developed an application called "echoserver" and I would like to share its details on Hacker News. The purpose of "echoserver" is to simplify the testing of HTTP clients. It functions as an echo server, meaning it responds to requests by echoing back the received data. This allows users to simulate various server responses and test their HTTP clients accordingly. With "echoserver," users can generate custom responses by specifying the desired status code, headers, and response body. This flexibility enables thorough testing of HTTP clients and simplifies the process of verifying…

    Hello HN, I’m one of the creators of ServBay. I built this because I got tired of the cognitive load required just to start coding. On my Mac, it was a fragile mix of Homebrew services and asdf conflicts. On Windows, managing PATH variables and fighting with Docker Desktop's resource usage was equally frustrating. I missed the simplicity of the MAMP/XAMPP era, but I needed to support modern stacks (Go, Rust, Node, etc.). What it is: ServBay is a native local development environment for both macOS and Windows. It is not a wrapper around Docker or VMs. It bundles everything you need into…

    Hi, I created httpdbg, a tool for Python developers to easily debug HTTP(S) client requests in Python programs. I developed it because I needed a tool that could help me trace the HTTP requests sent by my tests back to the corresponding methods in our API client. The goal of this tool is to simplify the debugging process, so I designed it to be as simple as possible. It requires no external dependencies, no setup, no superuser privileges, and no code modifications. I'm sharing it with you today because I use it regularly, and it seems like others have found it useful too—so it might be…
