The Future of Industrial Automation is OpenPLC

A flexible and modern industrial control stack. Open-source and hardware-agnostic by design, from microcontrollers to industrial servers.

Deploy a PLC in 60 seconds

The open standard for controls engineers worldwide

Trusted by engineers and academic institutions from early research to mission-critical manufacturing.

What open software-defined controls buy you

Decouple control logic from the hardware and change how your team works, what it returns, and how long it lasts.

Version control, collaboration and AI, in a browser

Real branches, commits and diffs on your control logic. Teams, permissions and shared libraries. CoPilot writes and reads ST, Python and C++ alongside you. Nothing to install, no dongle, no activation server.

Open-source core, with enterprise reliability

An open runtime, IDE and compiler carry no per-device licence to renew, and the difference compounds as the estate grows. Enterprise support, SLAs, compliance and fleet capabilities from Autonomy engineers.

Fleet-scale deployment

Push a validated program to one machine or to every line in every plant from the same place, with version history behind each deployment.

Continuity you can count on

Full source availability means a twenty-year asset never depends on one supplier staying in business, or on a roadmap you do not control. Extend it, fork it, or run it yourself: the platform stays yours.

Four ways to run the same toolchain

OpenPLC Editor, Autonomy Node, Autonomy Edge and Edge on-prem are one IEC 61131-3 toolchain in four places. What changes is where it runs and what it depends on, so this is the fastest way to find the one that fits how you work.

"The OpenPLC IDE sets the benchmark for quality and rigor in open industrial control. Integrating it into our DevOps platform has been instrumental in bringing this technology to enterprise customers"

Josef Waltl · CEO, Software Defined Automation

"In industrial cybersecurity research, OpenPLC has proven itself hardened and resilient. Its open architecture allows rigorous threat analysis and security testing, which is what makes it a trusted foundation for next-generation ICS defense."

Dr. Thomas Morris · Eminent Scholar, Professor & Director, The University of Alabama in Huntsville

"OpenPLC gives us a competitive edge on high-ROI automation projects. We deploy top-tier control logic quickly, and keep hardware choices open for our clients."

Vinicius Dias · CEO, Grupo Setta

"OpenPLC bridges traditional industrial operations and modern software engineering. It brings the elegance and software-defined capability of IT to the OT world, without giving up real-time control."

Dr. Stuart Evans · Distinguished Service Professor, Carnegie Mellon University

"OpenPLC has revolutionized how we teach industrial automation. The new v4 interface makes it accessible to students while maintaining the power professionals need."

Dr. Rishabh Das · Assistant Professor, Ohio University
