Carbon vs FUXA
Carbon and FUXA are both manufacturing (mrp/mes) software. Carbon is open source under AGPL-3.0, with 2.8k GitHub stars. FUXA is open source under MIT, with 5.2k GitHub stars.
Which to pick
- Pick Carbon when
- You make complex assemblies or high-mix, low-volume parts and want ERP, MES and quality in one system you can self-host or buy as Carbon Cloud.
- Pick FUXA when
- A plant or integrator wants browser-based HMI screens without licensing a commercial SCADA package.
Side by side
A manufacturing system that keeps quoting, orders, purchasing, inventory, MRP planning with finite-capacity scheduling, shop-floor travelers and labour capture, quality records and lot and serial traceability in one Postgres database.
A web-based SCADA and HMI tool for drawing process screens and dashboards connected to PLCs and devices over Modbus, OPC UA, MQTT and Siemens S7.
It is open core: the enterprise files, API keys and the MCP server need a paid plan or, when self-hosted, a commercial licence.
Fine for monitoring and light control, but it lacks the redundancy and certification that safety-critical sites expect.
