Wabbajack

Wabbajack is an automated Modlist (modpack) Installer that can reproduce an entire modding setup on another machine without bundling any assets or re-distributing any mods.

To get started, simply download the executable, then select a modlist from the gallery and click install. You will be prompted to log into the Nexus and then the app will automatically download extract, and configure the modlist for you. If the modlist requires downgrading Skyrim to a older version it will be done automatically. All the common mod tasks like MCM configuration, BSA extraction and creation, mod cleaning, ESL flagging, etc. are all handled via Wabbajack. Most modlists require only 5 clicks from a unmodded game to a fully modded game with up to 1500 mods.
