The DocsCanary Chrome extension surfaces inline freshness badges and stale section highlights directly on your docs site — so you know what to trust before you ship.
When you visit a page on your connected docs site, DocsCanary overlays freshness signals without any extra tools or tab switching.
Overall page score in the top-right corner
Dashed yellow border highlights sections flagged as potentially outdated
One click to the full page health report in DocsCanary
Install once, connect your DocsCanary account, and freshness data flows straight into every page you visit.
Add the DocsCanary extension from the Chrome Web Store. Takes under 30 seconds.
Sign in with your DocsCanary account. The extension syncs your connected docs sites automatically.
Visit any page on a connected docs site. Freshness badges and stale section highlights appear immediately.
Click any badge to jump directly to the full page health report in your DocsCanary dashboard.
A small badge in the top corner of every page shows the overall health score and letter grade — at a glance, without opening the dashboard.
Sections flagged as potentially stale get a subtle yellow dashed border with a tooltip showing the last relevant code change date.
Click any badge to open the full page health report in DocsCanary — with code change history, affected files, and suggested edits.
The extension only activates on docs sites you've already connected to DocsCanary. No activity on unrelated sites, ever.
Built on Chrome's latest extension platform for better security, performance, and longevity. Uses a service worker — not a persistent background page.
Authenticates via your existing DocsCanary session. No passwords stored in the extension. Token refreshes automatically in the background.
The DocsCanary extension is built against Manifest V3 — Chrome's current extension platform — with a minimal permission footprint and a content script that only activates on your connected docs hosts.
Requests only activeTab, storage, and identity. No broad host permissions — activates on connected docs sites only.
Injected declaratively via manifest host_permissions. Fetches page health from the DocsCanary API and overlays the UI non-destructively.
POST /api/extension/page-health returns freshness score, section-level annotations, and a dashboard deep-link URL.
Only the current page URL and org ID are sent to DocsCanary. No page HTML, no content, no browsing history.
