Does freecodecamp use Flarum?

I noticed that Flarum has similar functionalities to set forums than fcc. Since I was looking an open source alternative for forums, I was wondering whether fcc is using that technology?
If so, could somebody prompts an opinion about the reliability of Flarum (having into account that is a beta version yet)?
I’m also curious about if it is possible to deploy Flarum or other open source frameworks for forums in a static website (netlify)?

freeCodeCamp uses Discourse. It’s also open source like Flarum. I’ve never heard of it till now though.
