Modifold is a Kotlin CLI utility that allows you to transfer mods from curseforge to modrinth. This project is not affiliated with curseforge or modrinth
(Please make sure you are using java 9+, java 8 will not work)
The first thing you need to know is how to get a curseforge project ID. On the sidebar in the "About Project" tab, you can find that ID. You will need the numerical ID of every curseforge project you want to transfer to modrinth.
You will also need your curseforge username, this is used to verify the ownership of each mod being moved to modrinth, and will be discarded if it does not match. (You must be listed as an author, it's possible to be listed as a contributor but not an author)
Make sure 3rd party downloads are enabled on the project
There is a full -h menu, however the simplest invocation of modifold is
simply java -jar modifold.jar <Owner Name> <Curseforge Project IDs...>. This will walk you through any necessary
steps, with notices along the way, so please read carefully to avoid confusion. The tool will only move entire
projects, not individual files.
Some other common flags would be -l LICENSE to set the default license and -d DISCORD to set the discord link.
License field will be verified by the modrinth team so make sure you update it, its arr by default.
Remember to update the projects once created! Modifold creates the mods as drafts so that you can add sources, issues, delete if needed, ect.
If you want to automate publishing to modrinth I recommend the minotaur plugin (maintained by the modrinth team) or mc-publish.
Q: Will you ever add individual file transfer support?
A: No, that's out of scope for this, and im concerned it would make people rely on this tool instead of properly embracing modrinth.
Q: Is this safe to use?
A: Probably! It uses a proxy for the official 3rd party api, so it should be capable of accessing everything in a normal way.
Q: Modpack support?
A: Not really viable without much more work than I'm willing to put in, please see the amazing packwiz project for a tool that is mostly capable of that.
