- TabSub is a JavaScript PubSub tool that uses local storage for message sharing without requiring a server.
- It works on the same domain due to browser security measures separating local storage by domains.
- TabSub has been tested with 10 concurrent writers, showing no message loss and correct message order, though no warranty is provided.
- The tool is available on GitHub under the MIT license.
- Example usage includes syncing song playback across tabs and basic PubSub operations like publish, subscribe, and state retrieval.
