title: Open Source alternative for Confluent Kafka Connect MQTT Source and Sink connectors
body: <p>I want to connect by MQTT broker to Apache Kafka (non enterprise version and no confluent kafka managed service used). </p>
  
  <p>I was using Confluent's Kafka Connect MQTT source and sink but I realized it comes with a trial period of 30 days after which it requires a license. </p>
  
  <p>Are there any other open source / free options to use as a bidirectional bridge between Apache Kafka and mqtt broker.</p>
