Hey HN, one of the authors here.
Just wanted to specify that the github descriptions talks about "bash snippets", there is nothing specify in the codebase that's related to bash :))
You can install this tool yourself any time, web frontend, api and terminal client, and populate it with any content.
We are using our own live installation (https://ok-b.org) for bash snippets, because we find it such an obvious usecase (we are goldfish when it comes to bash snippets, haha).
