The manga site Kissmanga was shut down earlier today. Kissmanga had one of the biggest manga collections of Japanese Manga that was free to access. Despite the annoying pop-ups and security checks, it worked for people. However, If you open the site now, it gives you the message that Kissmanga was closed forever due to copyright claims. The entire database is supposedly deleted.
Kissmanga was not the official source for the manga uploaded on their site. Similarly, Kissanime hosted popular anime without any rights to stream these videos. Both sites were claimed for copyright and taken down. It is rumored that other popular non-official sites could meet the same fate.
It is still not clear why the site was shutdown suddenly. Sites like Kissanime have existed for over a decade and came back after persistent attacks. The story was broken on Reddit after the Kissanime support page announced it on their twitter handle. Many fans who prefer this site are now looking for alternatives.
As Kissmanga is no more, here are some of the official and non-official sources to read manga online. Each site has its pros and cons and you will need to visit them to find a suitable replacement.
