NATS Tapedeck

NATS Tapedeck is a focused tool for capturing NATS traffic and playing it back later—like a tape deck for your server.

Record
Connect to your NATS server, choose topics, and record messages into a single .natr file you can keep, share, or archive.

Replay
Open a recording and play it back with familiar controls: timeline scrub, speed, and optional looping—useful for demos, QA, and reproducing issues without a live feed. Recordings can be shared and do not contain broker or authentication information - only the recorded messages.

Organize
Browse your library of recordings, rename and manage them, and open .natr files.

Built for developers
Whether you work on IoT, home automation, or backend services, NATS Tapedeck helps you inspect message flow and repeat scenarios without re-rigging hardware or staging environments. Recordings can be saved and shared via a .natr file.

Note: You need network access to an NATS server. Server configuration, TLS, and authentication depend on your environment.
