01 — Why local-first

Your crawls shouldn't be someone else's product.

Cloud auditors built a business on uploading your clients' HTML and charging by the URL. Scannica flips it: the crawler runs on your desktop, results sit in a local SQLite database, and nothing is phoned home.

Cloud auditor

Pay to see your own site.

Upload
Send every URL & HTML response to a vendor server.
Quota
Pay per crawled URL. Forget it — surprise bill.
Data
Lives on a third-party box you don't control.
Speed
Bottlenecked on their crawl workers & your upload link.
Offline
Doesn't work. At all.
Scannica · on your desktop

Own the crawl. Own the data.

Upload
Zero bytes leave your laptop. The network is only for fetching the site you're auditing.
Quota
None. Crawl a million URLs if your disk holds it.
Data
A portable .scannica file you own, archive, and share.
Speed
Rust workers + SQLite WAL. Saturates your bandwidth, not their queue.
Offline
Open an old crawl on a plane. Works fine.
GEO · generative engine optimization

Built for the LLM era.

Traditional SEO auditors stop at title tags and canonicals. Scannica also checks what matters when Google's AI Overviews, ChatGPT, and Perplexity read your page: entity density, author signals, citation markup, llms.txt, Speakable schema, FAQ and Article structured data.

Nine GEO checks. No other desktop auditor ships them.

  • GEO_LOW_ENTITY_DENSITY
  • GEO_NO_ARTICLE_SCHEMA
  • GEO_NO_AUTHOR_ENTITY
  • GEO_NO_FAQ_SCHEMA
  • GEO_NO_LLMS_TXT
  • GEO_SPEAKABLE_MISSING
  • GEO_NO_CITE_ELEMENT
  • GEO_NO_CITE_SIGNALS
  • GEO_NO_EXTERNAL_CITATIONS
