Caddy vs Microsoft IIS: What are the differences?

What is Caddy? The HTTP/2 Web Server with Automatic HTTPS. Caddy is a production-ready open-source web server that is fast, easy to use, and makes you more productive. HTTP/2 and HTTPS by default.

What is Microsoft IIS? A web server for Microsoft Windows. Internet Information Services (IIS) for Windows Server is a flexible, secure and manageable Web server for hosting anything on the Web. From media streaming to web applications, IIS's scalable and open architecture is ready to handle the most demanding tasks.

Caddy and Microsoft IIS can be primarily classified as "Web Servers" tools.

"Easy HTTP/2 Server Push" is the primary reason why developers consider Caddy over the competitors, whereas "Great with .net" was stated as the key factor in picking Microsoft IIS.

Caddy is an open source tool with 22.7K GitHub stars and 1.79K GitHub forks. Here's a link to Caddy's open source repository on GitHub.

Microsoft, MIT, and Starbucks are some of the popular companies that use Microsoft IIS, whereas Caddy is used by RELEX Solutions, AresRPG, and Fresh8 Gaming. Microsoft IIS has a broader approval, being mentioned in 1498 company stacks & 312 developers stacks; compared to Caddy, which is listed in 14 company stacks and 5 developer stacks.

Advice on Caddy and Microsoft IIS

I am diving into web development, both front and back end. I feel comfortable with administration, scripting and moderate coding in bash, Python and C++, but I am also a Windows fan (i love inner conflict). What are the votes on web servers? IIS is expensive and restrictive (has Windows adoption of open source changed this?) Apache has the history but seems to be at the root of most of my Infosec issues, and I know nothing about nginx (is it too new to rely on?). And no, I don't know what I want to do on the web explicitly, but hosting and data storage (both cloud and tape) are possibilities. Ready, aim fire!

I would pick nginx over both IIS and Apace HTTP Server any day. Combine it with docker, and as you grow maybe even traefik, and you'll have a really flexible solution for serving http content where you can take sites and projects up and down without effort, easily move it between systems and dont have to handle any dependencies on your actual local machine.
