These are complete, open courses. All materials are under flexible copyright licenses and can be used/copied/adapted free of charge. If you want to use their platform for homework/grading/etc. then the cost to students is $5, to my knowledge, but this requires institutional participation with Lumen (better chance if you’d like to use multiple Lumen courses). Some customization is available.
These are complete OER textbooks under flexible copyright licenses, so they can be edited and adapted.
