Magic Wormhole Mailbox Server

Build Status Windows Build Status

This repository holds the code for the main server that Magic-Wormhole clients connect to. The server performs store-and-forward delivery for small key-exchange and control messages. Bulk data is sent over a direct TCP connection, or through a transit-relay.

Clients connect with WebSockets, for low-latency delivery in the happy case where both clients are attached at the same time. Message are stored in to enable non-simultaneous clients to make forward progress. The server uses a small SQLite database for persistence (and clients will reconnect automatically, allowing the server to be rebooted without losing state). An optional "usage DB" tracks historical activity for status monitoring and operational maintenance.

Running A Server

Note that the standard Magic-Wormhole command-line tool is preconfigured to use a mailbox server hosted by the project, so running your own server is only necessary for custom applications that use magic-wormhole as a library.

The mailbox server is deployed as a twist/twistd plugin. Running a basic server looks like this:

twist wormhole-mailbox --usage-db=usage.sqlite

Use twist wormhole-mailbox --help for more details.

If you use the default --port=tcp:4000, on a machine named, then clients can reach your server with the following option:

wormhole --relay-url=ws:// send FILENAME
