Spatterlight

Spatterlight is a native Cocoa application for macOS that runs a wide variety of interactive‑fiction game files. It supports formats such as AGT, Adrift, AdvSys, Alan, Glulx, Hugo, Level 9, Magnetic Scrolls, TADS (text‑only), Quill, and Z‑code (excluding version 6). The program also implements the Treaty of Babel standard, allowing it to read and display bibliographic metadata for the games it launches.

The software is aimed at users who want a single, macOS‑focused player for many classic and contemporary interactive‑fiction titles, reducing the need to manage separate interpreters for each format. Its integration of multiple interpreters behind a unified graphical interface simplifies the experience of loading and playing these text‑based adventures.

Spatterlight is distributed under the GNU General Public License, while the bundled interpreters and libraries retain their own open‑source licenses. Source code, binaries, and additional documentation are hosted on GitHub, and the project includes screenshots that illustrate the user interface.
