Equifax and TransUnion. They also tabulate the data using VantageScore which can be helpful to the customers. They also provide their customers with a way to e-file their taxes for free.
Here are a few sites which are similar to Credit Karma.

However, this does not mean that you need to be a customer of the company to sign up. It is free to register to the site. It is one of the few sites which have access to data from Experian and thus can provide the users with FICO score. But still, since there are various scores offered by FICO there might be some disparity in scores when you get your FICO score from a potential creditor.
This does not mean that the score you get at Discover is of no use as it gives a pretty good estimation of your credit score from the knowledge and educational point of view. Every time there’s an activity in your Experian credit report you get an alert on Discover. They also warn you if your Social Security number is being used on the dark web.
