Auto Downloader
Auto Downloader is a Fabric client utility that fetches the files a modpack or server expects, so players skip the manual setup.
What it does
When a player joins a modpack or a custom server, the mod checks for required mods, resource packs, shader packs and save files that are missing. Instead of asking the player to install each one by hand, it shows a clear prompt and can fetch the lot in one step. The aim is a smoother start for anyone connecting to a prepared setup.
The mod is client-side only, so servers run without it and only the player's own game needs it. Its behavior is set through a config file, and the author asks players to check that configuration and confirm they trust each source before use. The project is published for Fabric only, with files covering 1.20.1 – 1.20.6, and it is licensed under a custom license that is not open source.
Key features
Smart prompt
A single prompt lists what is missing and offers to fetch everything, replacing a manual install of each file.
Automatic fetching
Required mods, resource packs, shader packs and save files are fetched automatically once the player accepts the prompt.
Resource and shader packs
Resource packs and shader packs are handled alongside mods, so a modpack's visual content arrives with its code.
Save file handling
Save files a pack depends on can be fetched too, so a prepared world is ready when the player first opens it.
Config-driven behavior
Behavior is controlled through a configuration file, which the author recommends checking before the first use.
Smart management
The mod tracks what is already present, so files the player has are not fetched a second time.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Joining a modpack
A player who starts a modpack gets the missing content from one prompt rather than searching for each file.
Custom servers
A player connecting to a server with a custom experience receives the resource and shader packs the server relies on.
Who it’s for: The mod suits players who join modpacks or custom servers and want the required files fetched for them. Server owners who prepare a client setup can point players to it so the first connection needs less manual work.
