Key points

  • Blocks AI scrapers by planting invisible links that trigger content safeguards.
  • Server-side injection is recommended so scrapers that don't run JavaScript still see the canary.
  • For React (Next.js, Remix, etc.): add the Canary component from '@fuzzycanary/core/react' to the root layout.
  • For non-React frameworks: use getCanaryHtml() and insert it at the start of the <body> tag.
  • Client-side option: import '@fuzzycanary/core/auto' to auto-inject the canary at runtime for static sites.
  • Tool injects for every visitor including crawlers—test in staging before rolling out to production.
  • Open-source README with license and npm package available.

Why this matters

As AI models scrape public sites for training, site owners lose control of their content. Fuzzy Canary offers a pragmatic, low-cost way to deter automated scrapers by exploiting content safeguards — but it can affect indexing, so validate in staging and weigh SEO trade-offs before production use.
