Beyond the game

A short teaser of the real thing.

Journi DevOS is the full platform behind the voyage. The game shows a sliver of what it does; here’s the rest.

Governed

A fleet you can steer

One place to see every agent, set the rules they work under, and keep them on course — instead of a dozen tools running loose.

Equipped

Memory that carries over

Agents stop re-learning your codebase from scratch each session. Structure and past work persist, so every task starts informed.

Measured

Savings you can prove

Every run is priced — so the cost of AI coding becomes a number you can watch, the same one the game lets you feel.
