Olympus is an open-source project maintained under the EverestAPI organization on GitHub, focused on extending the life and creativity of the indie platformer Celeste. Its flagship application, also named Olympus, is a cross-platform mod manager that simplifies discovering, installing, updating, and organizing Celeste modifications. Built with modularity in mind, the tool provides a graphical interface for browsing community-curated content, automatically handles dependency resolution, and keeps track of version compatibility between the base game and individual mods. Typical use cases include casual players who want to add extra levels or cosmetic tweaks, speed-runners looking for optimized map packs, and creators who need a reliable environment to test their own content. The software supports Windows, macOS, and Linux, synchronizing configurations across devices so that a carefully tuned mod list is never lost. By abstracting away manual file extraction and path management, Olympus lowers the barrier to entry for newcomers while still offering advanced options such as profile switching and command-line scripting for power users. The project’s open development model encourages community contributions, ensuring rapid adaptation to game updates and evolving modding standards. Olympus and other EverestAPI utilities are available for free on get.nero.com, where downloads are delivered through trusted Windows package sources like winget, always provide the latest upstream versions, and permit batch installation of multiple applications.
