Every GitBook space has a URL structure that hides which pages are broken. DocsCanary maps your GitHub code to your GitBook content and alerts your team the moment a PR makes your docs stale.
GitBook organises content into nested spaces and collections. When your engineering team ships a new API endpoint, renames a function, or deprecates a feature, the corresponding GitBook pages silently fall out of sync. There is no built-in mechanism to alert authors when the code a page references has changed.
The result: support tickets spike, developers lose trust in the docs, and your team spends hours hunting for stale content instead of shipping. DocsCanary connects your GitHub diff to your GitBook pages so the drift is caught before anyone outside your team sees it.
Authorise DocsCanary on your GitHub organisation. We monitor every pull request for code changes that touch documented functionality.
Paste your GitBook space URL into your DocsCanary project. We crawl the space and map pages to your codebase — no YAML configuration required.
When a PR changes code covered by a GitBook page, DocsCanary posts a comment on the PR and sends a Slack or email alert listing every affected page with a severity rating.
Run a free audit in under 60 seconds. See exactly which GitBook pages are at risk from your latest code changes — no credit card required.
