What software can read comics for free?

I often use it, so I try to read comics. The cartoons on this software are very clear, and almost all of them are free.

There are also various types of long comics. Many excellent works have been published on this platform, but most of them need to be paid and occasionally limited.

There are two other things that are not commonly used, namely Dong Bo and Enchanting Comics, which have a lot of resources, but I think the picture quality is not very good, and many plots are puzzling.
