What are the best GitBook alternatives for internal QA and DevOps documentation?

We’re trying to improve how we document our internal QA processes, test case structures, and some of our CI/CD workflows. We’ve used GitBook in the past, but it’s starting to feel a bit restrictive, especially when it comes to integrating with our testing pipelines and version control.

Any teams here using tools that offer better flexibility or DevOps-friendly features? Ideally, we’d want:

  • Markdown support
  • Easy Git integration
  • Option to self-host (but not a must)
  • Simple team collaboration

Curious what others are using today
