Can anyone tell me where can I get a free domain? I need that for a project.

If you are still developing, you can use GitHub pages for a *.github.io domain, which is free

You can get a free domain here
freenom.com/en/index.html?lang=en

I think you can get free domain at
infinityfree.net/
Good luck.

Mee to I'm also searching for a free domain for one of my project

I'm also working on a project hmm can we collab ??

If so then it would be better talking via dev.to/connect
