OSI-licensed open source
Quality management systems (QMS) manage controlled documents, audits, non-conformances and corrective actions for standards like ISO 9001. Dedicated open-source QMS products are rare, so this page also covers general open-source tools teams assemble into a QMS.
Seven options are listed: two ERP-based quality modules (ERPNext, OCA Quality Control), OpenQMS, and four building blocks (Redmine, Paperless-ngx, BookStack, Mayan EDMS). Regulated industries should validate any tool against their own requirements. This page broadens beyond turnkey QMS products because few exist.

Quick answers to common questions
Few turnkey ones exist; most teams combine ERP modules, document management and issue tracking.
ISO 9001 does not mandate a tool, but you must control documents and records. Validate any tool yourself.
It is a small project, so evaluate carefully.

List it on TechLogHub and we'll review it for this guide.
