Watch how your users actually use your product

Dozor records real browser sessions with rrweb and lets you replay them in pixel-perfect detail. Self-hosted, framework-agnostic, free forever.

What it does

Built on rrweb, designed for teams who want to understand their users without shipping their data to a third-party vendor.

Pixel-perfect session replay
Every DOM mutation, mouse move, and input event captured and reconstructed in a sandboxed iframe. Scrub, skip idle time, jump by page — the replay player treats long sessions as first-class.
Tracked users and traits
Link sessions to your end users through a simple `identify()` call. Traits, activity timelines, and per-user session history — all derived from your own SDK payloads.
Slices for long sessions
Sessions automatically split on navigation or idle gaps, each slice independently replayable. No more scrubbing through a 40-minute tab that was open in the background.
Your data, your database
No third-party processors, no hidden telemetry. Point the SDK at your own dashboard, host on your own Postgres, own every byte.
