What is runescape-quicklaunch?

RuneScape Quick Launch is a small Windows tool for players of Old School RuneScape or RuneScape 3 who want to skip the extra step of clicking through the official Jagex Launcher window every time they play. Instead of opening the launcher, waiting, clicking Play, waiting again, then closing the leftover launcher window, this tool does all of that in the background and leaves you with a single taskbar icon and the game already open. It works by starting the official Jagex Launcher hidden, using flags the launcher itself supports for a silent start, then closing the launcher once the game client has appeared. It also tags the game window so it groups under the same pinned shortcut you click, giving you one taskbar icon instead of two. The tool never reads or stores your password or login tokens. All login is still handled by the official launcher exactly as if you had clicked Play yourself. To install it, a user needs Windows 10 or 11, the official Jagex Launcher already installed, and a game client. Setup is done by cloning the repository and running an installer script in PowerShell, or by running a one line command that downloads and runs the same script directly. Rather than shipping a compiled program, the installer compiles the source code on the user's own machine using the C# compiler that comes with Windows, which avoids Windows SmartScreen warnings that an unsigned downloaded program would trigger. The installer can add a desktop shortcut, a Start Menu entry, and an optional tray icon that lets a user quickly pick between characters, between Old School RuneScape and RuneScape 3, and between different game clients. Players with more than one character can save a separate shortcut for each one, so each shortcut launches straight into that specific character. The README explains that the tool does not automate or bypass anything inside the actual game, since it only starts and closes the official launcher using flags the launcher already provides. It is described as unofficial and not affiliated with Jagex or RuneLite. There are no signed downloadable releases, since compiling the code locally avoids the yearly cost of a signing certificate.
