What we're building

Open source tools and games — free to use, free to fork, free to build on.

Why we build this way

⛰️ For the People

Every tool and game we build comes from our own frustrations as developers and players. If it helps us, it'll help you. We don't build to extract — we build to share.

🔓 Open Source, Always

Our code ships under GPLv3. Use it, fork it, learn from it, build on it. The only thing you can't do is close the source. We believe great tools should be free.

🚫 No Ads. No Tracking.

We will never run ads, sell your data, or track your behavior. Our tools work for you, not for advertisers. If you like what we do, you can buy us lunch.

Where we're headed

Couloir is more than a studio. We're building a home base in Leavenworth, Washington — games, tools, and community under one roof.

Werkhaus

German: "workshop"

A CrossFit and strength training gym in the heart of Leavenworth's Bavarian village. Train hard, build something, come back stronger.

Leavenworth, WA
