List of Matrix servers

Matrix ecosystem consists of many servers which can be used for registration. Since many people joining us ask what server to choose, I've made a list.

It is also known for banning rooms and user accounts without prior notice for minor things such as expressing certain viewpoints. Luckily, changing matrix homeservers is as easy as switching email providers.
