Tubewarder acts a central outbound message gateway/hub by moving the clutter from applications which send messages automatically to a centric system. It provides channels for sending emails, text messages/sms, Facebook and Twitter direct messages, or triggering web services. Tubewarder cares for templating, logging, archiving, error handling, and user access. Make your applications cleaner by delegating automatic message sending to Tubewarder.

Tubewarder as a central message gateway/outbound message hub


Tubewarder is the bridge between your applications sending automatically generated messages (like user-welcome-mails, weekly reports, or newsletters) and the systems doing the actual work (like email servers or web services). Configuration is done using an easy-to-use integrated web interface. Applications send messages over it using a SOAP/XML or REST/JSON service.

The software is licensed under the terms of the GPLv3. You can use the Tubewarde for free for commercial and non-commercial purposes. We provide professional support in case you need it.
