Claim your listing
Is Gamma yours?
Claiming binds the listing to your SiteList account: edit the listing, respond to reviews, get a correction window on every publish, and open marketplace offers.
Sign in to bind ownership
The verification challenge is tied to one SiteList account. Sign in first, then prove control of gamma.app with DNS, a homepage meta tag, or a small well-known file.
Claiming is free and doesn't change the score — reviews stay independent either way. See how reviews work.
