Badge Twins
Compare two players' badges and see how much they really have in common.
Questions
How does Badge Twins work?
Type two Roblox usernames. It reads both players' badges and counts how many they have in common, then shows which games those shared badges came from.
How is the score worked out?
Shared badges divided by every badge either player has. Two players with identical collections score 100%.
What does earned on the same day mean?
Shared badges both players earned on the same calendar day, in UTC. A high number usually means you played together.
Do both inventories need to be public?
Yes. Roblox only shares badge history for inventories set to Everyone.
Why is it fast if I already used another badge tool?
Your browser keeps each scan for a day, so switching between badge tools only looks up what's new.
