Free while it's rough. Fair when it isn't.

Open beta runs for 1 more days. Every account gets the full Max-tier engine free until then. When OX Alpha's window closes, paid plans switch on and everyone drops to whichever tier they picked.

Why is everything free right now?

The engine currently runs on our own model, OX Alpha, which costs us nothing while it's in development. You get frontier access; we get real-world stress testing.

What happens on day 1?

Beta ends. Your account becomes a Free account automatically — nothing breaks, your projects stay. Pick Pro or Max whenever a build you need needs a heavier tier.

Which engine should I use?

Fast handles small systems and quick fixes. Standard is the default for complete multi-file features. Max adds a self-review pass for anything touching economy or persistence. Switching is one click in Studio.
