compact-logic-control: Embedded PLC, Visual programming for microcontroller

Hi Product Hunt! I’m Steffen, the developer behind Compact Logic Control.

CL grew out of my work on industrial automation and embedded systems. I wanted a practical way to build control and measurement applications on compact hardware—and keep them understandable and easy to change years later.

With CL, you connect function blocks to read sensors, control outputs, build sequences and create user interfaces. You can inspect live values and adjust the logic while it runs. The same workflow brings together hardware setup, control, visualization and diagnostics.

A few things that matter to me:
• Start without hardware using the integrated simulator.
• Run applications on supported microcontrollers, including ESP32-S3 and ESP32-P4.
• Keep the complete project on the controller and in its backups, so future changes don’t depend on the original development PC.

CL has evolved through more than 10 years of practical development and use in over 50 applications. I’m now sharing it with a wider community of makers, embedded developers and automation engineers.

It’s free for personal projects, education and testing. Commercial and OEM use have separate licensing options.

The images and videos show existing examples from the system. I’d love to hear: What would you build with CL, and what would you need to see to try it on your own project?

Thanks for taking a look!
