WAMP clients as separate works
------------------------------

We see any code which connects to Crossbar.io via WAMP as a separate
work. The Crossbar.io license (the AGPL v3) does not apply to WAMP
clients. This applies irrespective of where these run, i.e. also to
components which are run side-by-side within an native worker of type
router, which are run in a native worker of type container or in a guest
worker. We promise to stand by this view of the license. If you need
further assurance, you can email us at contact@crossbario.com for a
signed letter asserting the above promise.

We release all our client libraries (those provided by the `Autobahn
project <https://crossbar.io/autobahn/>`__ under non-copyleft licenses, which
allow their use for closed-source & commercial software. For other
client libraries see their respective licenses (these appear to be
universally non-copyleft as well).
