TauCeti.GG Tools is built to give Marathon players useful support before and between runs. It currently includes three active tools: Item Compare, Loadout Manager, and Quest Tracker. Together, they help you compare gear, build smarter loadouts, and keep track of upgrades, contracts, and materials in one place.

The Item Compare tool is for side-by-side stat checks. It lets you compare item specifications and customize weapons and implants with attachments to see how performance changes. It supports up to four comparison slots, which makes it useful when you are trying to figure out what is actually worth using instead of guessing. 

The Loadout Manager is your build planner and build-sharing tool. It lets players create, customize, and share Marathon builds using weapons, mods, implants, and equipment from the item database. It also includes Runner filters for Assassin, Destroyer, Recon, Rook, Thief, Triage, and Vandal, along with build browsing, tags, and sorting options like Popular, Most Liked, and Latest. 

The Quest Tracker (or Marathon Item Tracker) is built to track materials across faction upgrades and contracts, with a faction selector for Arachne, CyberAcme, MIDA, NuCaloric, Sekiguchi, and Traxus. It also includes progress stats, upgrade and contract filters, completion controls, and checklist management tools.
