# OT Fabric

**Website:** https://otfabric.io/  
**APIs profiled:** 2

OT Fabric (otfabric.io) builds open-source, MIT-licensed, pure-Go protocol libraries, command-line tools and Dockerized interoperability test suites for industrial operational technology (OT): Modbus, OPC UA, BACnet/IP, IEC 60870-5-104, IEC 61850, Siemens S7, OpenADR, OCPP, DNP3, IEEE 2030.5, EtherNet/IP, PROFINET, CANopen on CAN bus and KNX, plus SunSpec Modbus and IEC 61850 information models and Sparkplug B over MQTT. Its stated goal is 'unified data for industrial operations': breaking down OT data silos so industrial data is easy to discover, access and use across systems, sites and teams. It publishes libraries and CLIs rather than a hosted web API.
