   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…

   Httpdbg – A tool to trace the HTTP requests sent by your Python code▲200

   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…

    HTTP:COLON – A quick HTTP header/directive inspector and reference▲37

    Hi HN -- I built HTTP:COLON, a small, open-source web tool for quickly checking a site’s HTTP response headers and learning what they mean as you go. Link: https://httpcolon.dev/ What it does - Enter a URL and fetch its response headers - Groups common headers into handy buckets (cache, content, security) - Includes short docs/tooltips for headers and directives so you can look things up while debugging. I find hovering on highlighted headers quite useful! Supports different HTTP methods (GET/POST/PUT/DELETE) Deep links - You can link directly to a host,…
