It's pretty basic and missing a lot of features, but the session recording core is there.

For now, I built the backend just using Java, SpringBoot, PostgreSQL, Jooq.

The recording part uses rrewb: https://github.com/rrweb-io/rrweb

The frontend in general is just React, TanStack Query, TypeScript, and TailwindCSS.

Looking for early users, feedback, etc!
