All the available symbols, footprints and 3D models on SnapEDA are totally free. However, if you don't find the library that you need, you can request it using our InstaPart service and you'll get the Symbol and Footprint within 24 hours.
Also, if you're constantly requiring new footprints, we have different premium subscription options. You can see more about that here: https://www.snapeda.com/pricing/
