For what you're describing, a place for onboarding, docs, and connecting to dev tools like GitHub, Superthread is a good fit. The layout is a lot more opinionated than Notion to reduce clunky navigation or UI.
It’s a place where docs and tasks are connected, so you're not jumping between a wiki and a task tracker. Specifically for devs it also has sprint functionality.
So far we like the idea of this approach but haven't fully set it up yet
Another benefit: since the docs live in the repo, they’re easy to feed into AI tools.You just drop the relevant Markdown files in as context. This workflow has worked really well for us.
The only real headache was adding auth to our Wiki, but we eventually found a simple solution.
We have so much documentation in Notion for different parts of work: i.e. internal finance, support, marketing, sales, ad-hoc ideas docs. And then when dev and several parts of dev lifecycle are added to it, it looks like a clusterf*ck (excuse my language). Everything is in your face and navigation seems clunky when you organise things one under the other. And for some reason, editing docs feels like I'm typing on a remote server with 300ms delay (on my linux device, works smoothly on Mac).
This is a reason why I like Linear. An opinionated planning product.
