RePlaya is a self-hosted session replay tool that stores each session as a single S2 stream, eliminating the need for a separate database, message bus, or object store. It enables live tailing of active sessions and supports filtering, export, and secure deployment, leveraging S2's streaming primitives for a streamlined architecture.
