Versions:
tosu is a lightweight, open-source memory reader and data provider purpose-built for enthusiasts of the rhythm game osu!, offering a high-performance bridge between the running game process and external applications that wish to display real-time statistics. Positioned in the Games & Entertainment category, the software silently attaches to osu!’s memory space, extracts beat-map metadata, player accuracy, combo counters, hit-error data, and other live match variables, then exposes them through a minimal local web-server and JSON endpoints so that streaming tools, overlay plug-ins, or custom dashboards can visualize the information without injecting code or altering game files. Because it is purely read-only, tosu remains compatible with the osu! terms of service while giving tournament organizers, content creators, and competitive players a reliable way to broadcast detailed performance metrics to spectators or to archive them for post-match analysis. Version 4.18.0, the first numbered public release, emphasizes stability and low CPU overhead, ensuring that even on modest hardware the reader adds no perceptible input lag during fast-paced maps. The MIT-licensed codebase also invites developers to extend functionality, whether that means adding support for additional game modes, exporting data to CSV, or integrating with OBS through custom dock widgets. Users typically launch tosu before starting osu!, configure the desired output port, and then point their overlay or automation scripts to the corresponding localhost address; no further setup is required, and the utility exits cleanly when the game closes. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
