Invisionfree was one of the bigger free forum hosts. The website had over 600 000 boards and has boards that date back to 2002.
Zathyus Networks (the owner of Invisionfree) opened a new forum service, Zetaboards in 2011, and encouraged all users to migrate, although this was not mandatory (but once migrated, there was no way to move back, much to the anger of many users).
In 2018 it was announced (sort of, in a forum thread in the support forums) that everything would be migrating to Tapatalk, meaning forums would lose themes and other aspects. Invisionfree was partially archived alongside Zetaboards as they are very similar, however due to a non-numerical indexing system it is unclear how much was saved.
