There are several websites like FanFiction.net. It has a huge collection of Star Wars fan - made stories. You can search by different categories such as era (like the Clone Wars era or the Galactic Civil War era), character (if you're interested in a particular character's story), or even by the type of story (adventure, romance, etc.).
Archive of Our Own (AO3) is also a great place. It not only has a wide variety of Star Wars fan fiction but also has a good tagging system. This makes it easy to find stories that meet your specific interests. For example, if you like stories that explore the relationship between droids in the Star Wars universe, you can easily find them by using the relevant tags.
Some Star Wars fan forums also have sections dedicated to fan - made stories. For instance, the official Star Wars forums might have a subsection where fans share their creative works. Here, you can also interact with the authors, give feedback, and sometimes even participate in contests related to fan - made stories.
