putty.org your website?No, it isn't, and it never has been. We don't own it; we can't control it; we have no responsibility for anything it does.
putty.org was set up by an opportunist selling a competing SSH client for money, who initially used it to interpose adverts for their own commercial SSH implementation in the course of providing a link to our free one. Then in July 2025 it changed its content to host anti-vaccine propaganda. We have no idea what it might do next.
Since the start of PuTTY, the real PuTTY web site, run by the PuTTY team, has always been at https://www.chiark.greenend.org.uk/~sgtatham/putty/.
We don't recommend that anyone use putty.org as a convenient redirector, or indeed any other convenient landing page that is not ours. There are a few others, some set up in entirely good faith, but you never know.
As of August 2025, we have registered putty.software and made that into an official landing page. If you'd like a short easy URL, that's the one to use, especially if we move the main website there in future.
