How to implement notification system like DEV

I like the way notification system work in DEV but want to know how I can make notification system like that.

For web application ( in-app notification ) NOT push notifications

I know about GetStream but it is too costly.
It is better if someone tell me how to implement our own notification system

Thanks in advance.

it is good approach if you have time and team to implement your own notification system and for that I will suggest going through this blog: tannguyenit95.medium.com/designing...

and if you want to go with any notification server then i will suggest firebase it i think it is cost effective.

I would use Firebase with a listener to new events on a collection of your choice

This is a good point. Firebase can get pricey though so probably a simple solution I can implement my self on my server would be helpful.

I noticed that their notifications do not come as push nor emails rather just an in app notification and even though I refresh the page I see the notifications icon but once I click it, they are considered as read and I don't see them anymore.
