No Code Flow is a tech company that has found an interesting method to support Ukraine in its border defense war. As they say on their website “the behavior of Putin it is an insult to the free world and cannot be accepted by those who live in a democratic country", so they have developed a small script that you can insert on your site to block access from Russia.
How the No Code Flow script works
To this address find the code to copy/paste into the head of your website. When a user from Russia tries to access your site he will see a message urging the Russian user to protest against Putin and will invite him to make a donation to support Ukraine.
