Welcome to the page of niche operating systems. Here, you can get acquainted with niche/hobby operating systems developed in the last few decades. The majority of operating systems are sufficiently functional, a few, however, are real-mode operating systems, and some are even less developed and could be labeled as advanced boot loaders. More interesting operating systems on this page have memory management capabilities, multi-tasking capabilities, and file system support. Closed-source operating systems are omitted from this list.
