Desktop app

Linux

Linux support notice: Linux builds are not actively maintained and will only receive small patches. We are prioritizing Windows server builds because our current team is more familiar with that environment. If you would like to help improve Linux support, feel free to reach out on Discord for the source code and contribute.

Extract the archive, then run chmod +x install.sh && ./install.sh. Creates astro-loader in ~/.local/bin and a desktop entry. DLL injection is Windows-only — Linux dedicated servers should use headless below.

Headless loader (dedicated servers)

In-process proxy for servers with no desktop session. Drop next to the game binary (Windows) or preload with LD_PRELOAD (Linux). Includes auth, mod sync, and the token bridge.

Windows headless

Place version.dll beside the server executable and add astro_headless.ini.

Why Astro Loader

Always up to date

On launch, the loader checks Astro's servers for updates and installs them automatically — no manual reinstalls.

100% official mods

Every mod DLL comes from Astro's Lounge official distribution — verified, account-gated, and delivered only through this loader. No third-party repacks or unknown files.

Multi-game support

Switch between supported titles from one launcher — DLL access is tied to your Astro account.

Built for performance

Lightweight bootstrap installer and a focused UI — inject, update, and manage from one place.

Installation

1

Download for your OS

Windows: MSI (recommended), EXE, or portable zip. Linux: AstroLoader-linux.tar.gz, then run ./install.sh. Dedicated servers can skip the desktop app and use a headless build instead.

2

Install

Windows: run setup and choose a folder. Linux: the install script places the app under ~/.local/share/astro-loader and adds astro-loader to your PATH.

3

Sign in

Use your mod-loader username and password. Need access? Request an account from staff on Discord.

4

Sync & run

The app downloads the mod build that matches your OS. On Windows you can inject into a local server. On Linux dedicated hosts, prefer the headless loader with LD_PRELOAD.

FAQ

Are mods from Astro Loader safe?
Yes. The loader only downloads and injects mod DLLs from Astro's Lounge official servers after you sign in. That is the trusted source — do not use copies from random links, Discord DMs, or other sites. If it did not come through this official installer and updater, it is not supported.
Do I need a separate account?
Yes. Astro Loader uses mod-loader accounts created or approved by Astro's Lounge staff — not your Discord login alone. Open the app after install and sign in, or use “Request access” if you are new.
What's the difference between MSI, EXE, zip, and the Linux tarball?
MSI is the recommended Windows Installer package. EXE is a small bootstrap stub. Zip is the portable Windows app folder. On Linux, download the .tar.gz and run install.sh inside it (AppImage / binary + desktop entry).
What is the headless loader?
A tiny in-process helper for dedicated servers with no desktop session. Windows: drop version.dll next to the server exe. Linux: start the server with LD_PRELOAD=…/libastroheadless.so. It signs in, syncs the correct OS mod build, and serves the local token bridge the mod expects.
Antivirus flagged the download — is it safe?
New executables are sometimes flagged heuristically. Only download from this official page or astroslounge.com APIs. Mod binaries are equally official — served only through the loader after sign-in. If unsure, ask staff in Discord before running anything from elsewhere.
What is the status of Linux support?
Linux desktop and headless builds remain available, but they are not actively maintained and will only receive small patches. We are prioritizing Windows server builds because our current team is more familiar with that environment. If you would like to help improve Linux support, feel free to reach out on Discord for the source code and contribute.
macOS?
macOS is not supported. Astro Loader ships for Windows and Linux (64-bit) today.
