Why consider Nuclino alternatives?

There is not a lot of feedback online from customers on Nuclino. Compared to other knowledge-sharing tools, it doesn't have too many reviews on platforms such as G2 and Capterra. However, there are a few things that have popped up as drawbacks.

There are some user experience issues on the back end, as one user writes:

  • "When you create a collection, it creates a page you can't edit, which only has links to and the names of all the pages in the group, which doesn't look very good as a page. It would be better if that were a page that could be edited to function as that collection's home page." (source)

Another user highlighted the limitations of the Kanban board system:

  • "I would like it if the kanban board feature could also be used inside of workspaces, at a lower level, rather than just as a workspace." (source)

Last but not least, the free Nuclino plan is rather limited. With just 50 items and three canvases, you will barely scratch the surface of a solid knowledge base.
