UltraESB is a lightweight enterprise service bus (ESB) capable of supporting many transports and message formats natively. It allows messages to be mediated via Java or JSR 223 scripting languages through an API,[1] and is the first ESB to claim support for Zero-Copy proxying[2] of messages with Non-Blocking IO capabilities. In 2013, it was selected as the ESB and API Management platform by a recent Fortune #1 company based on its performance and stability.

The initial version was published in January 2010 [3] and the code was subsequently open sourced under the OSI approved Affero General Public License (AGPL) in 24th of August 2010.[4] Continuous nightly builds[5] are there to ensure the performance of latest development code.


Some of the key features of UltraESB are:

  • Use any IDE – Allowing users to choose any IDE for development significantly reduces the learning curve for development
  • Ability to unit test, along with close to 50% code coverage[6]
  • Easily extensible via third-party libraries, Spring configured beans and custom code
  • Support for number of message formats and transformations[7]
  • Support for payloads and protocols such as AS2, HL7, SOAP, REST, FIX transports such as MLLP/S, JMS, AMQP, FTP/S, SFTP and WS-Security, XACML and JTA XA transactions
  • Very light weight download of ~42MB for complete distribution (Minimal version < 9MB)
  • Support for clustering and fail-over for high-availability
  • Built-in metrics and JMX, CLI and Web based management

Supporting tools[edit]
