OpenMES

Judgement

What it is

Complete system

What it does

A manufacturing execution system for small shops with tablet screens for operators, production planning, work orders, quality checks, downtime tracking and MQTT machine data.

Adopt it when

A small woodworking, metal or assembly shop wants shop-floor tracking without enterprise MES licences.

Watch out

Under a year old and still at version 0.x, so expect changes; AGPL applies if you modify and host it for others.

Ready for

Experimental

Runs as

Self-hosted server and cloud service

Built with

PHP, Laravel, PostgreSQL and MQTT

How established

Young: started 8 months ago, latest release v0.28.0.

What the license allows

Use inside your business is unrestricted. If you change it and let customers use it over the internet, you must publish your changes.

Judged on 2026-11-03 from the project's README and GitHub data. The license and age lines are worked out directly.

Built from

Follow it down: OpenMES → Php-src → GCC → LLVM project → runs on a microchip
