Show HN: An open-source manufacturing ERP/MES/QMS
The whole system of record — ERP, MRP, MES and QMS — on Postgres you own. On-prem, in your VPC, or fully air-gapped. Open source, so you can audit every line before it ever touches your most sensitive records.
Two hard tech unicorns run Carbon on their own servers.
Defense and aerospace manufacturers handling CUI can't ship their record of production to someone else's cloud. Self-hosting Carbon keeps that data inside your own CMMC boundary — and for Enterprise deployments we hand you the SSP, POA&M and SPRS inputs an assessor will ask for.
Run a single shop or a multi-national manufacturing engine from one Postgres database inside your perimeter. Per-entity currency, chart of accounts and tax; consolidated books; inter-site transfers — none of it leaving your network.
Pull any serial number and get its full genealogy — material certs, operators, measurements, deviations — from a database that sits behind your own firewall. First article, NCR, CAPA and calibration on the same records as production.
Digital travelers, operator terminals, barcode tracking and finite-capacity scheduling — all executing against the copy of Carbon you host. No cloud dependency between the floor and the record.
The same source runs from a single Docker host to a multi-region deployment in your own cloud. No proprietary runtime, no lock-in.
→ Full deployment guides live in the documentation.
Self-hosted Carbon is the same codebase that runs the managed cloud — the Community edition free under AGPL-3.0, Enterprise features unlocked with a commercial license.
The whole application is on GitHub — a typed TypeScript monorepo on Postgres. The Community edition is licensed AGPL-3.0 and free to self-host; Enterprise modules and air-gapped licensing require a commercial license. Audit it against your security requirements before a single record ever lands in it.
