// EDITOR'S TAKE

OpenReplay is the closest on the part people actually use Hotjar for, with detailed session replay plus network and console context, and it is designed to be self-hosted so recordings never leave your infrastructure. PostHog gives you replay alongside product analytics and flags if you want one tool for everything, while Fathom Analytics is privacy-friendly traffic reporting only and will not replace the replay or feedback side at all.
