Supercharge Your Modpack with Technic's Solder

Solder helps you lower bandwidth usage, keep old versions of your modpack available to users and provides faster, streamlined updates. You won't know how you managed a modpack before you used Solder.

Over 1100 modpacks are using Solder on the Technic Platform right now!

What is Solder?

TechnicSolder is an API that sits between a modpack repository and the launcher. It allows you to easily manage multiple modpacks in one single location. It's the same API we use to distribute our modpacks!

Using Solder also means your packs will download each mod individually. This means the launcher can check MD5's against each version of a mod and if it hasn't changed, use the cached version of the mod instead. What does this mean? Small incremental updates to your modpack doesn't mean redownloading the whole thing every time!

Solder also interfaces with the Technic Platform using an API key you can generate through your account there. When Solder has this key it can directly interact with your Platform account. When creating new modpacks you will be able to import any packs you have registered in your Solder install. It will also create detailed mod lists on your Platform page! (assuming you have the respective data filled out in Solder) Neat huh?

Technic uses Solder

All of Technic's modpacks on the Technic Platform use Solder for distribution. Solder lets us push updates quickly to millions of players without lighting our servers on fire. Without it, Technic wouldn't be possible!

Solder is not easy

Solder is intended for experienced system administrators and is by no means very easy to setup. You should have at least a small amount of experience in a LEMP environment before getting started with Solder!

Solder is Open Source

Solder is licensed under the MIT License. What does this mean? It means its completely open source and you can do anything you want with it! We also appreciate any help with the development of Solder, so fork away and contribute!
