A full team wiki with good search and enough knobs to justify Docker.
the catchIt is a flexible wiki, but Slite is easier to adopt and offers more polished hosted search, AI answers and knowledge-maintenance features with no server administration.
the verdict →all Slite alternatives →
A polished wiki, provided you are willing to become its part-time sysadmin.
the catchIt provides a capable wiki but not Nuclino's lightweight canvas, graph and board workflow, and it asks someone to administer a database-backed server.
the verdict →all Nuclino alternatives →
A modern wiki with enough knobs to remind you that you are now the administrator
