I like to use readeck. But that is mostly a read later thing, i think.

Nice! I needed that info for the mobile Firefox settings! Thank you

I definitely think that Silverbullet fits in the same space as Bookstack and Docmost. I recently moved my notes and stuff to Silverbullet, and I really like the fact that it is just .md files on disk, with some very nice organisation around it, and extensibility with lua scripting and css styling. And OIDC - a must in my home lab :)

From a glance, it looks like Silverbullet does almost all the same things, without having features behind a paywall. No build in MCP, but there are third parties, and not as much granularity in the permissions for each user. But OIDC and multiple spaces with real time editing, @ mentions and much more.
