How do you add /blog to your business site without writing code?

Hi, I was exploring if there is an easy way to add /blog to your website other than expensive solutions. I found ghost, but it needs an additional $100/m for this feature alone. WordPress at /blog, I am not really sure how to do that. I created my own blogging platform https://esyblog.com for the same purpose. It can connect a domain and can also be connected as /blog to any site. Example blog: https://nanodevpro.com/blog
