An open-source manufacturing ERP system designed for secure, self-hosted deployment

Why self-hosted ERP matters for regulated manufacturing

A new open-source enterprise resource planning platform has been released that integrates ERP, MRP, MES, and QMS functions into a single system running on PostgreSQL. Designed for on-premises, virtual private cloud, or air-gapped environments, it allows manufacturers to maintain full control over their data within compliance boundaries such as CMMC. The software is freely available for inspection and modification before deployment.

The system positions itself as a complete system of record for manufacturing operations, combining core business functions typically handled by separate proprietary tools. By running on PostgreSQL—a database the user owns and manages—it eliminates reliance on external vendors for data storage and processing. This architecture supports organizations with strict data sovereignty or cybersecurity requirements, particularly those in defense contracting or regulated industries where external SaaS solutions may pose risks. The developers emphasize transparency, inviting users to audit every line of code before it interacts with sensitive production or financial data.

How does open-source licensing affect long-term usability

Manufacturers in sectors like aerospace, defense, and medical devices often face stringent cybersecurity mandates that limit their use of cloud-based software. Traditional ERP systems frequently require internet connectivity or third-party hosting, creating potential vulnerabilities. This open-source alternative addresses those concerns by enabling deployment in isolated networks where data never leaves the organization’s infrastructure. The ability to run the system in an air-gapped setup means it can operate without any external network connection, a critical feature for facilities handling classified or export-controlled information. Early adopters highlight the flexibility to customize workflows without waiting for vendor updates or facing licensing restrictions.

Unlike proprietary ERP platforms that lock users into subscription models and vendor-specific upgrade paths, this system’s open-source nature allows perpetual use without ongoing fees. Organizations can modify the code to match their unique processes, add integrations with legacy machinery, or adapt reporting tools to internal standards. While the core software is free, the project offers optional licensed support and hosted console access for teams preferring assisted deployment. This hybrid model aims to balance accessibility with sustainability, ensuring the project can continue development while remaining accessible to smaller shops that lack large IT teams. The absence of vendor lock-in also reduces long-term total cost of ownership compared to traditional enterprise systems.

What compliance standards does this system support? The software is designed to operate within CMMC boundaries and supports air-gapped deployment, helping organizations meet data protection requirements for controlled unclassified information.

Frequently Asked Questions

Is technical expertise required to install and maintain it? Basic PostgreSQL and Linux administration skills are needed for self-hosting, though optional console services are available to simplify setup and monitoring for less experienced teams.

Can it integrate with existing shop floor equipment? Yes, the MES component allows connection to machines and sensors via standard protocols, enabling real-time production tracking without replacing current hardware.
