The tesseract Lemmy app, has a little overview from mediabiasfactcheck.com (MBFC). It seems like a clever way to foster a healthy community.
If you click on the ranking you get details.
EDIT: Sorry to stir up an old hornet's nest.
EDIT2: Commenters have some valid criticisms of MBFC. Even if there are flaws, I would like to celebrate all attempts at elevating the conversations we are having.
is there an open source, decentralized alterntative to MBFC ?
I can't find one.

No. And there never should be. And here's why. Bear with me for a moment but consider this. Part of the problem with this sort of thing is that people want their hands held. They want to be told what to think. Not to think critically for themselves. No matter how well intentioned. Such systems will always be sought to be abused. To manipulate people and their opinions. And at best they will always be subject to bias and blindness. The truly keep them from ever being universally useful.
Basic training and education in critical thinking skills will be far more to help people. Than relying on an app no matter how well intentioned to tell them how to think about something.
Held hands? No. Not everyone has the time, energy or training to evaluate a site's trust comprehensively. I want to see what other people think in case they spot what I missed. I also want to see if people are even taking about the site and why.
I mean, can you imagine? There are so many sites out there I can't spend three hours fact-checking one for the sake of replying to an argument. And then all that work going to waste for the benefit of nobody else.
Not to mention all the domain-specific knowledge you'd need to properly evaluate claims. All the critical thinking skills in the world are worthless if you don't have contextual knowledge of whatever subject is in the news. It's just not realistic for everyone to be a policy wonk.
