Server Owners! Tired of having to manually check if Mods/Plugins are updated for a new Minecraft Version? I fixed it for you! :)
New MC version just dropped. You know the drill.
Open Modrinth. Search first mod. "No versions for 1.21.11." Close tab. Search next mod. "No versions for 1.21.11." Close tab. Repeat 27 more times. Cry
modcheck.sh fixes this problem for you! You give it your mod list and a target MC version, and it checks Modrinth to tell you which mods are updated, which are outdated, and which it couldn't find; all at once.
Next time someone in your Discord asks "is [mod] updated yet?" — just send them the link so they can check themselves!
It works for both Fabric and Paper.
Three ways to input your mods:
- Paste a list of mod names
- Upload your
.jarfiles directly; it reads the metadata so you don't have to type anything - Search Modrinth to add mods one by one
Once checked, you can:
- Download a ZIP of all the updated mods in one click (great for migrating a server)
- Share a link to your results so your whole server can see what's safe to update to (links last 90 days)
Ideal for: server admins updating to a new MC version, modpack maintainers, or anyone building a new modded instance who wants to know what's actually available before committing to a version.
I built this tool to give back to the Minecraft community since I always hated having to update all my mods manually, taking up a long time with hundreds of tabs open. I hope you all find this useful and can enjoy it! :)
