Enter two gamertags and this tool looks up both public Xbox Live profiles at once, then lines up their Gamerscore, Account Tier, Reputation, and current Online Status side by side. Any field a profile doesn't expose is shown as unavailable — never guessed or estimated. Gamerscore itself has become enough of a milestone that Microsoft now shows tiered badges for it directly on console and in player profiles (Xbox Wire), which is part of why comparing it head-to-head is worth doing. Because everything runs through the same public profile data the console itself uses, the numbers you see when you compare Xbox Gamertags here match what each player would see on their own device — there's no separate scoring system layered on top.

Opening two separate profile pages and mentally lining up the numbers is slow, and it's easy to lose track of which Gamerscore, tier, or reputation belonged to which player. When you compare Xbox Gamertags with this tool, both lookups run at the same time and land in one shared view, so the higher Gamerscore, the matching Account Tier, and the current Online Status are all visible at a glance instead of split across two browser tabs. This is especially handy for settling a friendly rivalry, checking who's ahead going into a new season of achievement hunting, or simply seeing how a friend's account stacks up against your own before a squad night. If you ever want to change a gamertag before running a fresh comparison, Xbox Support's official guide covers the process end to end: how to change your Xbox gamertag, along with the naming rules and limits explained in the Xbox gamertag update FAQ.
