Clairvio

The product is an on-demand session replay and diagnostics tool that records what users see in the browser along with console output, network requests, and navigation events to reproduce bugs without relying on vague reports. It sells to engineering and support teams in software companies that handle customer bug reports. It is delivered as a SaaS with a dormant under-1 kB loader that only activates the full capture library when a magic link is opened, avoiding always-on tracking.
