This mod will stop Forge mods from loading - it does not allow Forge and Fabric mods to be used together!
Make sure you back up before you join worlds where you have used Forge mods previously - as all the blocks/items added by those mods will disappear.
Jumploader
Jumploader is a mod that allows the use of Fabric mods in CurseForge modpacks, by loading Fabric as if it were a Forge mod. It works on both the client and server, however it's only necessary on the server if you want to launch the game using tools that only support Forge. Jumploader is fully configurable to load any Minecraft version and mod loader, but by default it will load the Fabric loader and library versions corresponding to your current version of the game. It only loads if your game was launched from Forge/ModLauncher, so it won't do anything if your Minecraft launcher already supports Fabric.
What it does
- Loads Fabric (or a different configured mod loader) instead of Forge, from a Forge installation.
- Automatically loads the latest Fabric loader version for your version of the game, with no required configuration.
- If necessary, loads the unpatched Minecraft game, so that Fabric can be used with it.
- Ensures that Fabric and Mixin don't see the classes loaded by ModLauncher.
What it doesn't do
- Jumploader doesn't let you run Fabric mods with Forge or Forge mods with Fabric - it hijacks the launching process so that Forge never loads. See Patchwork for a project aiming to let you use Forge mods with Fabric.
- Jumploader doesn't currently work very well on the client for loading a Minecraft game with a different major version (including snapshots) to the currently loaded game, as supplementary assets (such as sounds) are downloaded separately by the game launcher. The Asset Validator mod fixes this issue.
Requirements
Requires a Forge version that uses ModLauncher (or ModLauncher on it's own, without Forge) - this usually means 1.13 or newer.

oh my gosh this is genius i need this now
So if i understand this right if i were to use this mod on lets say my Valhelsia 3 installation and i add the mod to it I still couldnt just drag a fabric mod into the modpack and it would work?
In reply to puurpleflaame:
No. It would break every forge mod in the pack.
In reply to puurpleflaame:
I mean, the fabric mod would work, but none of the other ones would and it would break all your worlds
When I use this, and then use the 'attach leads to logs' mod, it tells me I need fabric loader 0.11.2 or higher.
According to the config files, jumploader loads 0.11.1 for MC version 1.16.5.
Could you update it so that it uses the latest version of fabric loader?
In reply to Master_Bucketsmith:
You'll want to edit the jumploader.json config file, and change the pinFabricLoaderVersion value to the version you want to install. Jumploader picks the latest version on first launch, but doesn't automatically change it afterwards to prevent breaking existing packs.
In reply to comp500:
Oh thank you.
Is the Jumploader splash/loadscreen supposed to show every time? I recently installed Jumploader and hadn't used it in a while. I noticed the first load or 2, there was a Jumploader window before switching to the MC window. But now when I launch it, nothing comes up 'till the MC load screen comes up. Just curious if that's a bug or if it's meant to only show while it's setting up Fabric, as that extra Jumploader window was kinda neat inside that initial load period.
In reply to ThatMechGuy:
It only appears when downloading Fabric, as that can take a while. It wouldn't really make sense to make the loading screen open all the time, as it'd only appear for a fraction of a second - the actual Jumploader launching process is very fast.
In reply to comp500:
Gotcha. Makes sense. I was just hoping for something beyond Jumploader's scope I guess. That weird delay when opening a Fabric modpack, before the MC loadscreen finally shows up, confuses a lot of new players. When I saw the Jumploader screen, I thought "problem fixed!". But then it didn't come back so I figured I'd ask. Ah well. Maybe the Fabric team will do something about that someday. Anything to let players know that stuff is happening.
does this works for wall jump mod (fabric ver)?
In reply to atwk:
I would think so, yes.
In reply to atwk:
well, it loads fabric mods as forge mods, so it should work with any fabric mod.
Trying to help my son to get his first modpack ever (All of Fabric 3- 1.16.5) to work on a PC with Minecraft Java edition 1.16.5 installed. All went well with installing CurseForge, and the modpack. But after pressing play on the All of Fabric, 3 Jumploader fails to load with errors like "Failed to resolve jars:java.net.SocketException:Connection reset " and "Failed to resolve jars:java.net.ConnectException:Connection timed out: connect". I have no clue where to even begin, please advice this mom.

Do you use a VPN or proxy to connect to the internet? Also check if https://meta.fabricmc.net/ works in your browser.
would this work with labymod?
In reply to Kingmeep24:
no , labymod is it's own loader essentially and an untrustworthy one at that
labymod is blacklisted and will get you banned in a lot of the big popular mini games servers like hypixel due to the mod having a lot of cheating traits within it like a radar minimap and such
In reply to BradW0:
just to clarify, labymod is use at your own risk on hypixel, means it not officially bannable but it's not officially allowed either, i personally have use it like two years ago and i can say it's safe, but idk about the newer releases though
In reply to apawhat:
it's a use at your own risk pretty much anywhere, there is parts of labymod that would be "if the person used it at great advantage and was great at using it" to win in a PvP/mini game then yes you will be banned if found to have used it to gain unfair advantage and better someone doing it completely vanilla.
as it also sends some strange packets back to the server which is why server owners don't like it.
which is why I would just avoid using labymod to cut the risk of being banned.
it is always best before using certain client side mods that may give you an unfair advantage over others to check server owners rules and just check that certain mods and such are allowed.
for instance a client-side mod like "jumpoverfences" would give a player an unfair advantage in a hot potato,hide n seek kind of mini game as vanilla can't actually do such thing.
In reply to BradW0:
fair enough
