Flint API Loader (1.21.5, 1.20.1) – An Open-Source Modloader

Flint API Loader (1.21.5, 1.20.1) is a tiny, open-source modloader system, aimed at players playing on Vanilla and Plugin Servers, like Spigot/Paper etc. This is NOT a replacement for Fabric, Quilt, NeoForge or Forge, and will not allow you to run mods made for any of them. Flint has it’s own API for mods. Flint is a hobby/learning project, and is not intended to replace any other modloader out there, and will not allow you to run a server.

How to install:

• Download the Flint API Loader from below.
• Open the installer. In the window you can select the Minecraft version, loader version (latest recommended), and the install location (default recommended).
• To show snapshots in the Minecraft versions dropdown, tick the ‘Show Snapshots’ checkbox.
• The install location is the location of Minecraft Launcher. If you want to change your instance’s directory use Minecraft Launcher’s instance options.
• Press Install. A new game version and profile will be created in the launcher’s menu, which you can now use to launch Flint.
• You may then want to launch your newly created instance once, and then add Flint API to your instance’s modules folder as most mods will need it.
