   ServBay▲399

   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…

    A simple echo server for testing HTTP clients▲59

    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…

    The HTTP Garden – A Parser Vulnerability Research Tool▲75

    I wrote this tool during an internship at Narf Industries in 2023. It's a REPL that allows for quickly developing, testing, and fuzzing for HTTP request smuggling attack payloads. I started the internship having never worked with web servers, and have now found over 100 HTTP implementation bugs. I attribute this mostly to the ease of experimentation in the Garden. REPL-oriented fuzzing is just a really good interface for finding parsing bugs. It's pretty neat to able to run a differential fuzzer, categorize and display all the discovered discrepancies, then let a human pick through them and…
