Software studio

We build software that doesn’t bite.

Snowfox Builds is a small software studio. Right now we're focused on AI tools that make hard software easier to build.

What we’re building

SilverquiLLM

Active

An open benchmark that tests how well coding agents turn new Magic: The Gathering sets into code.

Why it matters. MTG is a brutal stress test for coding agents — long rules, weird edge cases, and state that changes every turn. It's a thorough yet affordable test for long-running coding agents.
How it’s built. Python, Docker, and pytest, so anyone can run it reproducibly.

Snowfox Builds is just getting started. SilverquiLLM is the first of several tools and experiments — expect more projects, write-ups in the future.

A one-person studio that likes to tackle difficult problems. (And yes, there’s a real dog behind the mascot .)
