Which software do you think is better for SEO and overall? Nodebb, Discourse, Vanilla Forum Users?

Hello friends. I am looking for software for a different and open-source project. I have researched a lot and even conducted trials by setting up and deleting servers on DigitalOcean, but I am undecided. The project will be a community based on Linux, which I can describe as a place for encountered problems and exchange of ideas. It is more of a Stack Overflow style than a forum atmosphere.

In short, friends, is there anyone who knows, has tried, or uses these? Do you have any different recommendations? Is there anything you can say about a specific open-source software? It would be greatly appreciated if you could give some ideas.

Note: I have used SMF, Mybb, Phpbb, Xenforo, Vbulletin; I do not want to prefer these software. If you are going to recommend them, you can eliminate them right away, friends. What I want to do is not the classic forum mold.

Hello,

You might know the site Alternativeto.net, but I wanted to share it anyway.
For example, following @cryptosam’s example, we can search for stackoverflow and find self-hosted software with the open source or free option.

I hope it helps.

I’ll take a look at these too. Thanks.

I installed something called Flarum, but it didn’t quite settle right. I think I’m going back to Discourse. It seemed like the most stable one.

Here is the demo: https://discuss.flarum.org
