Lucee Server

Lucee Server (or simply Lucee) is a dynamic, Java based, tag and scripting language used for rapid web application development.

Lucee simplifies technologies like webservices (REST, SOAP, HTTP), ORM (Hibernate), searching (Lucene), datasources (MSSQL, Oracle, MySQL and others), caching (infinispan, ehcache, and memcached) and many more.

Lucee provides a compatibility layer for Adobe ColdFusion © CFML using less resources and delivering better performance.

You can build Lucee from source or grab one of our distributions:

Alternatively try the super-useful CommandBox standalone developer tools for CFML powered by Lucee.

Building Lucee from Source

You can find detailed instructions on how to build Lucee from source.

Lucee has a lot of testcases, there are a number of handy build flags which can be used to avoid running the entire Lucee test suite (which takes a while) when you are working on a specific feature (Lucee 6.+ only).

Lucee uses TestBox as our test framework, we have a customised CFML wrapper around TestBox which can be found in the root directory under /test.

The test suites use a range of Test Services, like s3, database, ftp, etc. You can see how they are configured in _setupTestServices.cfc via the source code.

System Requirements

Lucee is a JVM language running as a servlet on just about any servlet container; including Apache Tomcat, Eclipse Jetty, JBoss AS, and GlassFish.

We standardise on Apache Tomcat for installers and Docker containers as there is only so much time in the day.


The Lucee team “treats slowness as a bug". Many performance tests have shown Lucee to perform faster than other CFML engines.

Lucee attempts to resolve many inconsistencies found in traditional CFML; either forcing changes in language behavior, or providing configurable options in the Lucee Administrator.

For more peruse the Lucee Manifesto.

The Lucee team is always open to feedback and active at CFML community events, and is keen to remind people that Lucee is a community project.
