Hey Leo Gopal, with Devblog you have both! :D
You can retain your independence and blog on your domain, while still being present on the feeds of Hashnode users. All the content is solely yours and you can always export it in a single click along with all the comments.
I used to blog on Wordpress, Medium, and I even built my own blog.... I enjoyed building it more than writing on it, and I failed to keep it updated at all times.
What are your concerns with using Devblog?
