Carbon is the open-source manufacturing ERP/MES/QMS. Quote, plan, buy, build, inspect and ship on one live model of your factory — from a ten-person prototype shop to a rate-production line.
And some of the world's most innovative manufacturers
Best ERP/MRP/MES system I've ever seen in a 22-year career across defense and automotive. Native Onshape integration means we synchronize all our data without extra PLM connectors — good UX, modern integrations, open source, open API and MCP, cloud or on-prem. We run our whole electric-vehicle engineering and manufacturing business on Carbon, and I couldn't imagine going back to a legacy system.

Configure to order
Unfork your BOM.
Parameterize the part, not the paperwork. Rules drive the bill of materials, the routing, the price before you quote it.
→ Rule-based BOM and routing generation
→ Revision control with effectivity dates
→ Rolled-up cost at any configuration

Manufacturing execution
Real-time, real cost shop floor.
Every part, hour, barcode, and deviation tracked and handled in real-time.
→ Digital travelers with work instructions
→ QR and barcode tracking on every unit
→ Finite capacity scheduling that reacts

Quality
Traceability is the default state.
First article inspection, non-conformance, CAPA and gauge calibration sit on the same records as production. Pull any serial number and get its full genealogy — material certs, operators, measurements, deviations.
→ Serial and lot genealogy, forwards and back
→ NCR to CAPA workflow with sign-off
→ Certificates generated from live data

Multi-entity · Multi-location
Every site on one ledger.
Carbon allows you to a scale from a single-entity, single-location operation, to a multi-national, multi-location manufacturing engine with consolidated accounts.
→ Multi-entity accounting with intercompany transactions
→ Per-entity currency, COA and tax, consolidated books
→ Multi-location planning with inter-site transfers

If it has a bill of materials, Carbon runs it.
Regulated or not, one-off or rate production — the primitives are the same. The configuration is yours.
Keep CUI inside your own boundary. Deploy on a single box, your own VPC, or fully air-gapped for defense programs that have to meet CMMC and ITAR requirements.
Your database
One Postgres schema, and it's yours
ERP, MRP, MES and QMS on a single database you control, with row-level security. Your data never leaves your perimeter — no vendor cloud, no third-party data lake.

Audit it before you deploy it
The whole application is on GitHub — the Community edition under AGPL-3.0. Read every line, run a security review, and extend it to fit your process.
Trusted
Auditable by construction.

Ask your agent what it thinks
Carbon's source code is available. Copy the prompt below into your favorite LLM.
I'm deciding whether Carbon would be the approach for my manufacturing business. Download the repo https://github.com/crbnos/carbon and do an audit of the capabilities. Then interview me about my manufacturing process, goals, and tools I use. Finish with 3-5 specific things Carbon could do for me.
Generated straight from Carbon's schema — 381 resources and 1,641 endpoints, with typed clients for TypeScript, Python, C#, and cURL.
MCP server
Agent-ready by default
A built-in MCP server exposes 1,374 operations across 15 modules through three discovery tools. Permissions are baked in — an agent can never do what its identity can't.
