I haven’t tried Fumadocs yet, but it looks really clean. Curious how it holds up for larger doc sites or more API-heavy use cases. Does it support things like OpenAPI integration or is it mainly markdown-based?

Nuxt Content is not just a documentation tool - it is a structured-content-to-web converting tool in general. Maybe you meant Docus template built atop of it by its authors? And it needs Nuxt to run, so "Vue developers" might as well want to use Vitepress, which doesn't require them to have Nuxt included, is incredibly fast to start and HMR during developing, and it actually is used mainly for building docs sites.

Some nice contenders on this list.
Have you stumbled upon Voiden by any chance?
It's an offline API devtool, enabling devs to spec, test, and document APIs offline in a single place.

Swagger drove me nuts last week 😅 When our legacy API PDFs get updated, I just dump them in ChatGOT - it spit out a summary and let me ask stuff like ‘Show auth flow changes’ instead of Ctrl-F hell. Saved me 2 hours on Monday alone.

Great article. Bookstack is what I have been using. It has good features and functionalities.. Organizing documents is great 👍

Great review, thanks! Please add Antora that usually goes with Asciidoc. In some sense, Antora for Asciidoc is what Hugo/Jekyll/etc. are for Markdown.

Love the hands-on approach here, really tough to actually test that many!
Curious if you found any pain points when switching between these tools or managing long-term documentation across teams?

i’ve enjoyed all of the research you’ve put into this project it adds up
you ever find yourself switching tools again and again or does one actually stick

I used Zudoku for the Outpost docs and am pleased with the flexibility, customisation, and results.

I have been using mdBook for quite sometime and I find it the easiest to work with.
