I've used several similar systems including Drupal, Confluence, and Document360, and Archbee has proven the best. Editing and organization of documents is easy. They have markdownbased editor similar to the one Confluence has, but more focused on documentation needs. There is a special workflow block which is excellent for step-by-step instructions. Support has also been very prompt and good in answering questions, and the dev team is actively working to continue to improve the system (I know because I use it every day and get prompts to restart the app when something has changed). Working with Archbee has been a very good experience.

Archbee is so easy to use. I like all native integrations that help us to create notes very quickly.

It has an easy-to-use block-based writing experience that gives you the "Medium.com" experience while writing documentation. But don't get me wrong … it has many more blocks than the mentioned service. Furthermore, you can add your CNAME meaning domain to point to each document(s) and that makes it really neat and white-labeled for that matter (if you need that). It is also good to know that I can onboard more co-writers at any point if the need arises or a project has more than one stakeholder.
