## What it is
Carbon is an open-core manufacturing operating system combining ERP, MES, and QMS functionality in a single web application built on Supabase, React Router, and TypeScript. It covers quoting, sales orders, MRP planning, purchasing, shop-floor execution, quality inspection, shipping, invoicing, and accounting, with a REST API, webhooks, and an MCP server for AI clients.

## Use cases
- run a manufacturing ERP for make-to-order production
- track shop floor jobs and work instructions with an MES
- manage quality inspections, FAI and NCRs
- generate MRP plans and purchase orders from sales demand
- configure-to-order bills of materials with rules
- query manufacturing data from Claude or Cursor via MCP
- self-host an open-source alternative to legacy ERP systems
- trace serialized parts and lots through production

## When to choose
- you run discrete manufacturing (assembly, contract manufacturing, high-volume, configure-to-order) and want a modern API-first system
- you want ERP, MES, and QMS unified on one data model instead of separate tools
- you want to self-host or extend an open-core platform with your own apps via REST API or MCP
- you need traceability, nested BoMs, and realtime shop-floor data

## When to avoid
- you need process manufacturing (chemicals, food batching) rather than discrete assembly
- you need capacity planning or simulation, which are still on the roadmap
- you want a turnkey on-premise product without Supabase/Postgres infrastructure to manage
- you require a permissively licensed OSS project - the license is custom (NOASSERTION) open-core
