Preprints are typically shared via repositories known as preprint servers. ArXiv is a widely used preprint server in computer science and physics. You can find more examples of discipline-specific preprint servers below.
Some preprint servers feature comment features so other researchers can provide feedback.
In some disciplines such as computer science the use of preprints is a widely established practice.
Where possible it may be best to reference a final paper (author accepted manuscript) in a literature review where it is available. Speak to your supervisor about the the use of preprints in your discipline.
