I built a free, self-hosted CMMS called Workshop Control Center (WCC)

Developer David Zoltan Csiki released Workshop Control Center (WCC), a free, self-hosted computerized maintenance management system (CMMS) under an open-source license, with unlimited seats, 34 languages, a fully offline Android companion app, and AI agent readiness via dedicated documentation files. The software, currently in Open Beta (OB1.0.0), targets real workshops and factories by removing per-seat pricing and providing features such as work order lifecycle tracking, preventive maintenance, inventory ledger, procurement, reliability KPIs, and granular role-based access control.

Free. Unlimited seats. Source available.

A modern CMMS built for real workshops and factories.

Most maintenance software charges per seat.

That forces teams to share logins — and destroys data quality.

WCC removes the seat meter completely.
