Reviewers mostly see GitBook as an easy, flexible way to write and publish documentation, handbooks, wikis, and even personal sites. Several praise its clean interface, strong output, and features like analytics and Lens for helping teams spot gaps and answer support questions. But criticism is consistent on stability: some say updates break the UI, features and extensions feel half-finished, and the editor can differ from the published result, especially with tables. Founders of
Bucket and
Quash add that their docs stay readable and current.
