it is same to same preev website with a different domain. but yeah. it is good as a backup. just checked the website and it is working smooth. hopefully you'll sustain it for the future. just don't get down like preev dead.
i assume preev shut down their website because of low funding. they were not making any money from the website and obviously no one supported them with donations. so they were left with no options but to shut down the website.
