One engineer · two product lines · offline
Two product lines, one workshop: process-control engineering software that produces real drawings, and Mac utilities that do their job without an account.
Free during launch Every app is free for a limited period right now — macOS, Windows and browser builds, and the iOS build by sideloading. No account, no key.

01Two lines
They look unrelated until you notice both are built to be used offline, by one person, for years.

Mac tools
Specific annoyances, fixed properly. Small apps that open fast, work without a network, and stay out of the menu bar unless they belong there.
02Selected work
Each shows a different part of the method: a drawing pipeline, a viewer that respects your files, and a search index that lives in one SQLite database.
03Local-first
Both lines run on the hardware in front of you. There is no account to create, no upload step, and no telemetry to switch off.
Install, unplug the network, keep working. IntelliLogic ships a single-file offline web build, RungCraft runs from a folder in the browser, and Wiretoss moves files over your own LAN.
Findarium indexes into a SQLite library in a folder you choose. Models are opened from disk. Nothing is copied to a server we run, because we do not run one.
ShadowFS is early access and is labelled that way. Cable-tray design exists in NWD Studio's repository but not in the shipping build. We would rather list the gaps than pad a feature table.
04Services
Some problems are specific enough to warrant a purpose-built instrument. That is usually a conversation, then a build.
Services · digital twin
A reduced-order model of a multi-stack alkaline electrolyser, its gas-liquid separation, lye circulation and heat exchange — every actuator and instrument exposed over OPC UA, running at wall-clock speed.
Services · studies
With several electrolysers feeding one separation system, what Cv do the outlet valves need, and how does the control strategy behave when load moves? Valve OTS answers that with a dynamic model instead of a spreadsheet.
Services · custom
If a workflow can be described precisely, it can usually be built. One engineer, a short path from problem to working tool, and no platform to adopt first.
05Pro edition
Sold directly from this site, alongside the free builds. The feature split and the price are published when it goes on sale — no tier names invented before then.

Licence pricing is being finalised. Until it is published we quote directly — and the open-source products can be read before you decide.
