Carbon
Carbon combines ERP, MRP, MES, and QMS functions for manufacturers planning materials, running production, managing quality, and tracking actual costs. Product rules can generate bills of materials, routings, and quoted prices, with revision control and effectivity dates. Shop-floor tools include digital travelers, work instructions, QR and barcode tracking, and finite-capacity scheduling. First articles, nonconformances, CAPAs, and calibrations can be linked to production records, serials, and lots. Carbon is aimed at discrete manufacturers, including makers in defense, aerospace, automotive, medical devices, electronics, robotics, energy, space, semiconductors, and industrial equipment. Integrations include Onshape, SolidWorks, Slack, Jira, QuickBooks, Xero, and others. It provides REST endpoints, webhooks, an MCP server, and typed client generation for several languages. Deployment options include managed cloud, customer cloud accounts, Docker, on-premises, and air-gapped networks; air-gapped deployment is an Enterprise feature. Community includes core functionality under AGPL-3.0. Starter costs $40 a month, billed per user monthly, and a 30-day trial is listed.
