What is ser?

ser is a lightweight tool that lets you instantly turn any folder on your computer into a mini web server. If you've ever needed to quickly share files with someone on your network, or preview a website you're building, this tool makes it happen with a single command. It's designed as a faster, simpler replacement for a common Python command that does the same thing. Here's how it works: you open your terminal, navigate to the folder you want to share, and type ser. The program starts a local web server that hosts the contents of that folder. By default, it serves the current directory at localhost:8080, meaning you can open your browser and see the files immediately. You can also easily customize it with simple flags, if you want a different port, you just add -p 8088, or if you want to serve a different folder, you just pass the directory path. You can also expose it to your broader network by specifying a different address. This is useful for a few different scenarios. A web developer building a static site can use it to quickly see how their HTML and CSS look in a browser. If you're in a meeting and want to quickly share a folder of PDFs or images with colleagues on the same Wi-Fi, you can serve the directory and give them a URL. It's also handy for downloading files from your desktop to your phone without needing a cable or cloud service. The project is built with Go, which makes it a single, fast executable file with no external dependencies. Unlike the Python alternative it replaces, you don't need a specific programming language environment installed to run it.
