blacksmith.cx is an independent New York app studio that makes small, well-made apps. We are blacksmith.cx LLC, a New York limited liability company formed on November 2, 2026.
We build apps for ourselves and our clients. Most stay small on purpose. We believe in apps that are useful, sharp, and stand alone—each with its own name, its own people, and its own place in the world.
