This blog itself is an experiment. There is no server/api running on the cloud that it gets the data from. The entire site is pre-rendered with the content built-in and then hosted on gitlab pages. A blogpost is coming soon to explain how it works.
Here's a list of the wonderful open source tools that helped
Front-end Framework : Nuxt.js
Headless CMS : Ghost (hosted on my local machine)
Blog Theme : Custom - Blog pages are heavily inspired by the amazing Casper theme from Ghost.
CSS Utility Framework : Tailwindcss
Deployment Pipelines & Hosting : GitLab
Thumbnails & Reponsive Images generation : Batch Image Resizer
Total cost of running this website: $0, some energy and time.
