There are a bunch of field-specific preprint services like arXiv: PsyArXiv, SocARXIV, engrXiV, AgriXiv, etc. The OSF also hosts preprints for various disciplines.
The important thing to remember is that preprints are not peer-reviewed and have not been vetted in any way. A paper may change a lot (or just a little) between preprint submission and final publication. A recent paper of mine had a few sections added for clarity, which wouldn’t appear in a preprint.
