CAD and BIM
for engineers who'd
rather own their tools.
Local-first. No subscription. No cloud lock-in. Built by an engineer, for the work. Buy it, install it, draft. Your files live on your disk in formats you control.
Modern where it helps. Boring where it matters.
One payment. Yours.
No subscription, no annual renewal, no per-seat tax.
Your disk. Your files.
Local-first storage. DXF, PDF, SVG out — formats you own.
I&C is first-class
Instruments, loops, P&ID symbols treated as data, not as blocks.
AI is optional
Bring your own key, or switch it off. Every workflow is complete without it.

Long-term"Every tool here started as a problem we couldn't find a good answer to. We built the answer and priced it like we'd want to pay for it. No subscriptions, no investors, no slide decks. Just you, the tools, and whatever comes next."
