fiveb.ar

AI-first, cookieless, EU-hosted web analytics. It gives AI agents access to a site's traffic, client and server errors, and page speed, with a one-script-tag install and no cookie banner or free-trial friction. Data is monitored across networks of websites and API/MCP endpoints, served through the project's own custom CDN so no data is at rest in the US or with a US company.
