All my dev docs are spread across Notion, Google Drive, a Github repo and text notes in Slack. I'm currently hiring devs and figured I should get these in order first.

A place where you can save dev onboarding, design docs, api docs, devops stuff, emergency handbook, potentially connect Github for code search, connect Linear and maybe other frequently used dev tools. And it all feels effortless to maintain and sync.

In my previous experiences at startups, we used Confluence and Phabricator. Is there anything new startups use these days?
