Notion Sites is a website publishing platform built on top of Notion's document and database infrastructure, commonly used by indie makers, startups, and teams who want to publish portfolios, landing pages, documentation, or wikis directly from their Notion workspaces without managing traditional hosting. The platform leaves a distinct technical footprint that AIWebsiteDetector.com's detection engine identifies through a combination of 2 script patterns, 2 HTML patterns, and 1 meta tag pattern embedded in the rendered page source. Detection signals typically include references to Notion's core JavaScript assets served from Notion's own CDN infrastructure, along with characteristic HTML attributes and meta tag signatures that persist across pages built on the platform. These layered signals allow the detector to distinguish native Notion Sites deployments from third-party tools like Super or Potion that merely style Notion content, improving confidence accuracy across varied site configurations. Notion Sites is hosted entirely on Notion's infrastructure under the notion.site domain or custom domains, making it one of the more structurally consistent CMS targets to fingerprint — the absence of self-hosting means the underlying markup patterns remain largely uniform across the ecosystem.
