Wolfite's Obby System (WOS)
More actions
Wolfite's Obby System, or WOS for short, is one of the first source-available free and popular obby system, originally created in December of 2021 by @Wolf1te. Originally purposed for DCOs (difficulty chart obbies), its widespread usage through 2023-present saw it be used in casual tower obbies and other unrelated obbies. According to wolfite.dev (the official documentation site), WOS has amassed over 10,000 installs and over 90,000,000+ collective contributed visits as of 2025[1].
Unfortunately, the last update for WOS was in April of 2024, as currently, the system is EOL (END OF LIFE), meaning no future updates will be provided, along with no support for issues on free or paid versions of the system. You can read more here. Although, despite being EOL, it is still a highly functional system if configured effectively, and is widely regarded as the best free obby system still.
