Built by us
More than the apps. A workshop that ships.
HandelOS is one operator's studio. Alongside the trade apps, that's meant live products with real deployments, sites for real businesses, and a stack of AI systems that research, build and run the work. Here's all of it — nothing dressed up as more than it is.

This site · brand + apps
The umbrella brand site you're reading now — the front door to the whole trade-app family.
The flagship · manufacturing
WerkOS — the AI operating system for your factory.
Our manufacturing flagship for metal fab, CNC and auto-ancillary job shops. Not another dashboard: one vital sign, the Plant Pulse, showing exactly where the plant leaks money.
🏭 Plant Pulse
Early access
📍 Built for the shop floor
- Beyond the office door. Accounting stops at billing — WerkOS runs the shop floor.
- One price for the whole plant. No per-seat maths, no setup that dies on day two.
- The one number, before month-end. Scrap, idle machines and late jobs surface while you can still fix them.
For real businesses
Client work.
Sites and platforms built for real companies — some live, some mid-build. Labelled as they actually are.

Reviewed & appreciated · Berlin
Berlin businesses vouch for the work.
Shree Living (student-housing operations) and a Berlin sport-brand wholesaler (website & online store) — real platforms we built end-to-end, used and reviewed by the teams they run. Still in build, and labelled honestly.
The engine room
AI systems that do the work.
Under the products sits a stack of AI systems — agent crews that research markets, write code, grade their own runs, and market what gets built. This is how one operator ships like a studio.

The Studio
Design-firm mode
A principal-design-engineer workflow: audit → redesign → verify, hard-stopping at a localhost preview so nothing ships without sign-off.
