I have created my own website ! You can find it here - https://aquibdeveloper.com
And you can also publish your extensions on this website !
Already @Aditya_Nanda did.
Its a simple and basic website.
Highly recommend to open the website on your laptop/PC.
How to publish my extension on that website?
I figured it out, sorry.
I looked there. Nothing but names and a link to download. Extensions descriptions are missing.
