It integrates well with other Microsoft products and technologies such as .NET framework and Microsoft SQL Server.

Caddy supports automatic HTTPS by default using Let’s Encrypt, making it easy to secure websites with SSL certificates.


In conclusion, there are several popular web server software options available in the market, each with its own unique features and strengths. Apache HTTP Server remains one of the most widely used options due to its stability and flexibility. Nginx has gained popularity for its performance and scalability.

Microsoft IIS is a preferred choice for Windows environments, while LiteSpeed offers improved performance as a drop-in replacement for Apache. Caddy stands out with its simplicity and built-in HTTPS support.
