All third-party sites are use at own risk.

SteamDB by xPaw, a person that does have very good connections to some big people in the business these days, as long as you do not get caught up clicking a phishing link disguised as the real SteamDB, his site is safe to use.

yes 100%

no its owned by Isra*l

the sight steamdb is safe enough, however if you download something, you never know and you will have to do it at your own risk. Personally I only use it to see what the best sale was on a given product, beyond that I don't really use it.

The site, as is, is as safe as any other website.

Adding free stuff there to your Steam account actually doesn't download anything, it just adds the licenses to the account.

It has a lot more to offer like Sales & Deals, Upcoming releases, Free promotions, Bundles, Price changes, When is next sale?, Free Packages etc. and is safe to use.

It also helps finding different ID's, manifests and many other info's about games, like patch notes, which files have changed in the depots like a history after updates.

It's imo a must-have in the bookmarks regarding Steam-related sites.

As well as steamstat.us is.

What are you downloading from the site itself?
