Just Unknown

About

A small studio with a systems mindset.

Just Unknown started in 2026 to build the tools we wanted and the games we wanted to play, and to keep both honest by shipping.

Principles

How we work

Build the tool, ship the product

Every engine feature exists because a game needed it. Every package is extracted from something that shipped.

Performance is a feature

Fixed timesteps, zero-GC hot paths and measured frame budgets, on phones and on microcontrollers alike.

Open by default

The engine and the just_* packages are BSD-3 licensed and developed in public.
