Cs2 Match History Checker

Check instantly if you've played CS2 Premier or Faceit matches with any Steam user — directly from their profile. No logins, no accounts created, no risk.

WHAT IT DOES

• Adds a "CS2 Match History" panel to every Steam profile you visit
• Two tabs: Premier and Faceit
• Finds every match you've played together (teammate or opponent)
• Full scoreboard: map, score, date, K/A/D, MVPs, HS%
• "View on Faceit" link to open the match room
• "Load more matches" pagination to scan deeper history
• Assign a custom alias to any profile (saved locally, only you see it)
• Preference: open Faceit tab by default

USAGE EXAMPLES

• Spot recurring teammates or opponents
• Check if that "random" from last night was actually a smurf
• Tag a player as "cheater", "smurf", "friend" or "duo partner" for next time
• Remember matches you played with friends

Custom aliases:
• Stored only in your local browser storage
• Never synced to any server, never shared
• Visible only to you on your own machine

Steam Web API key (optional):
