invisit is a cookieless analytics tool that shows where every visit started, including which AI assistant cited the site, which thread or README linked it, what the visitor read and whether they paid.

The free tier covers 20,000 events a month plus 5,000 error reports, and paid plans start at $14 a month for 100,000 events, rising to $199 for 10 million, with every feature included.
Only visitor events are billed: crawler hits, web vitals and engagement pings are recorded and itemised but never count toward the event limit, and yearly billing is 25% cheaper.
Funnels, heatmaps, revenue by source, alerts, an API and MCP access all ship on the paid plans, alongside a tracker that is open source.

Setup is one script tag on Next.js, Astro, SvelteKit, WordPress or Cloudflare Workers, and no cookie banner is needed because nothing is stored on the visitor's device.
