Is This Mod Legit?
This mod has been replaced with a more secure web app over at isthismodlegit.anopensauce.dev!
Is This Mod Legit? Is a mod that scans your mods folder, and checks them against Modrinth to verify if they have been tampered with or not. This can be useful when identifying if a mod in your modpack is from a trustworthy source or not. This mod works for up to 300 individual .jar files. (past that, modrinth will stop checking the files.)
Supports 1.18.2 and onward, and works on both the client and server! Requires an internet connection to function every time you add/remove a mod.
