I suggest Coda or Notion. Flexible canvas’s that you can make your own.

I’m not really convinced anymore that I need a “wiki tool” to create a wiki because the old binary definitions of this sector are changing. Plus, with Coda/Notion you can use them for way more than just a Confluence type of use case, which is quite appealing so you don’t have to have a specific tool just for an internal wiki (which means additional training, creds, tribal knowledge, etc.)

Personally I like Coda better because it’s essentially a doc with relational databases (instead of spreasheet-like tables, which pose issues over time), which means you can build pretty powerful referential schemas, often times just as robust — if not more so — than something like Slite.
