Quality OS v0.4.1 | Self-hosted Quality Management for regulated manufacturing.

Over the last several months I’ve been developing a personal project called Quality OS where I have been building the Quality Management System I have always wanted.

It started as a way to explore better document control and change management for regulated manufacturing environments. Since then it has grown into a self-hosted Quality Management platform designed around practical quality system workflows rather than generic document storage.

Current capabilities include:

Controlled document lifecycle
Integrated change control and RFC workflow
Deterministic document comparison
Structured comparison of references, responsibilities and CCPs
AI-assisted review summaries using a locally hosted LLM (Ollama)
Review queue and document history
Local processing with no cloud dependency

One of the design goals has been ensuring that AI assists reviewers rather than replacing them. Document comparisons are generated deterministically first, with AI producing a review summary from verified changes, maintaining traceability throughout the review process.

There is still plenty to build, including a side-by-side review cockpit, electronic approvals and additional QMS modules, but it’s been rewarding to see the platform evolve from an idea into something I use every week.
