Everything in one place

Built for modding PAYDAY 3

No more dragging .pak files into folders by hand. Modrex handles discovery, install, updates, and launch - so you can get back to the heist.

Browse modworkshop

Search the full PAYDAY 3 catalog with categories, sorting, and rich mod pages - images, changelogs, and dependencies.

One-click install

Install, enable, disable, and remove in a click. Supports .pak, .zip, and .7z, with multi-file mods grouped as one.

Organize in folders

Sort your library into nested folders of any depth, with drag-and-drop reordering that sticks.

Smart updates

Modrex detects out-of-date mods and lets you update them selectively - or all at once.

Launch your way

Boot modded or vanilla straight from the app. Vanilla launches hide your mods and restore them on exit.

Auto-detects your install

Finds PAYDAY 3 across Steam, Epic Games, and the Xbox App - and identifies stray .pak files by hash.
