# lighty.io

> lighty.io is a lightweight SDK powered by OpenDaylight for building Software-Defined Networking (SDN) controllers in plain Java SE — no OSGi, no Karaf, no container overhead. Developed by PANTHEON.tech.

lighty.io repackages OpenDaylight's core components (MD-SAL, YANG Tools, Controller) to run standalone in Java SE, with optional northbound (RESTCONF, NETCONF, gNMI) and southbound (NETCONF, OpenFlow, SNMP, gNMI) plugins. It boots faster and uses less memory than a standard OpenDaylight/Karaf distribution, and lets developers use any Java framework (Spring Boot, Quarkus, Micronaut) alongside their controller logic.
