An open-source manufacturing ERP/MES/QMS

In plain words

Carbon is an open-source manufacturing platform that combines ERP, MRP, MES, and QMS functionality on a PostgreSQL database users control and host themselves. It runs on-premises, in private VPCs, or air-gapped environments, making it suitable for defense and aerospace manufacturers handling controlled unclassified information who need to keep production records within their own security boundaries. The source code is available for audit under AGPL-3.0, and enterprise deployments include compliance documentation support.

From the sources

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. 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…from carbon.ms

  Neosync – Open-Source Data Anonymization for Postgres and MySQL2024 · github.com · ▲246

  Hey HN, we're Evis and Nick and we're excited to be launching Neosync (https://www.github.com/nucleuscloud/neosync). Neosync is an open source platform that helps developers anonymize production data, generate synthetic data and sync it across their environments for better testing, debugging and developer experience. Most developers and teams have some version of a database seed script that creates some mock data for their local and stage databases. The problem is that production data is messy and it’s very difficult to replicate that with mock data. This causes two big…

  Talanoa▲343

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
