Micronaut is an open source JVM-based framework for building lightweight microservices.

It is designed to avoid reflection, thus reducing memory consumption and improving start times. Features which would typically be implemented at run-time are instead pre-computed at compile time.

It was created by Graeme Rocher, who also created the Grails framework. In June 2020, Rocher co-founded the Micronaut Foundation, which aims to "advance innovation and adoption of Micronaut". Micronaut is continually developed and maintained by Object Computing Inc.
