Hephaestus
Modify all the things, then do it again! Fabric port of Tinkers' Construct
Quick answer
Which Hephaestus release should I use?
Hephaestus 1.18.2-3.5.2.312 targets 1.18.2 with Fabric. Installation on the client is optional. Installation on the dedicated server is optional. 1 required mod needs a matching file.
Where it goes
Is Hephaestus required on the client, server, or both?
Installation on the client is optional. Installation on the dedicated server is optional.
The source marks this as usable on both the client and server.
What else does Hephaestus 1.18.2-3.5.2.312 need?
1.18.2-3.5.2.312. Change the file and its required mods may change too.
Install Fabric API first, but 1 required mod has no matching file for this setup. Do not mix loader builds to force a match. 2 come through another mod in the chain.
2 extra mods were pulled in by other dependencies. Indented rows show who needs each one. We only count dependency files that match this setup. A file for another loader does not fill the gap.

About this project
What does Hephaestus add?
Hephaestus is a Fabric port of the Forge mod Tinkers' Construct.
Hephaestus is a mod about putting tools together in a wide variety of ways, then modifying them until they turn into something else. The tools never disappear and can be named and changed to your heart's desire. Once you make them, they're yours forever. Many different materials can be used to make your tools.
This mod doesn't add anything besides making it compatible with Fabric, however there are plans later to add some exclusive content and possibly tweak some of the current content. For more info about the mod itself see the Tinkers' Construct page.
1.18.2 builds have critical bugs that may ruin game-play experience. They are effectively archived.
No support will be given if you are using a 1.18.2 build
A 1.19.2 PORT IS NOT HAPPENING!
I don't have the time and motivation to do 1.19.2.
So stop harassing me to support older versions.
