Has anyone seen Jira done well? And no matter how it's done, it is always slow and bloated.
Confluence is slow but pretty simple, standard wiki otherwise. Obviously, if I had a choice, it'd be nothing Atlassian.
git+markdown limits editing to developers only.
Jira has improved massively the last 2-3 years, it's faster than GitHub now in my experience
The question was about developer documentation, so non-developers was put to the side in my answer. We are also now in the agentic age, so git + markdown is operationally much more aligned with the primary doc producer and consumer. We are more managers and editors these days.
I have not seen the improvement in Jira: if anything, it only feels slower.
GitHub Issues today seem bloated too, so perhaps your frame of reference has moved backwards while you weren't looking and suddenly Jira is fast?
I use Jira daily for ~8 years, it has become faster in it's own comparison over time.
Jira is a highly customizable beast, it does matter how your Jira wizard sets things up
