ReadMe makes beautiful API docs, but it has no way to know when your codebase changes. DocsCanary bridges that gap — monitoring your Readme.io project for documentation freshness and alerting you the moment drift appears.
Readme.io is purpose-built for API documentation — versioned references, interactive Try It consoles, and auto-generated OpenAPI pages. But when your team updates an endpoint, adds a required field, or changes authentication flows, the manually authored guides and tutorials in ReadMe are not updated automatically. The reference updates, the prose goes stale.
DocsCanary watches your GitHub repository and cross-references every code change against your ReadMe project. When a PR introduces drift, your team gets a precise list of affected pages before the merge — keeping your ReadMe documentation freshness high without slowing down your release cadence.
Install the DocsCanary GitHub app. It inspects every pull request diff for changes that affect documented behaviour.
Enter your ReadMe project slug. DocsCanary uses the ReadMe API to index your guides, reference pages, and changelogs.
When a PR touches code covered by a ReadMe page, DocsCanary comments on the PR and optionally notifies via Slack or email — before the merge.
Free audit in under 60 seconds. See exactly which Readme.io pages are at risk from your latest code changes — no credit card required.
