Ooni Koda 2 vs Karu 12: Gas or Multi-Fuel?

The Ooni Koda 2 and the Ooni Karu 12 split on fuel before anything else: the Koda 2 runs on propane only, while the Karu 12 burns wood or charcoal by default, with Ooni's gas burner attachment available as a separate purchase. Past that, the Koda 2 takes a larger 14-inch pizza against the Karu 12's 12-inch deck, and the Karu 12 is the lighter of the two ovens. Both are cordierite-stone-deck ovens from the same maker, which is why fuel and size end up doing most of the work in telling them apart.

The short answer

Choose the Koda 2 if…

• You want a propane oven with no burner attachment to buy or fit — gas is the only fuel it runs on.
• A 14-inch pizza is the size you want, and a built-in burner matters more than a live-fire feel.
• You'd rather not shop for wood or charcoal before every bake.

Choose the Karu 12 if…

• You want the option of wood or charcoal, with gas available later if you add Ooni's burner attachment.
• A 12-inch pizza suits how you cook, and the lighter of the two — 12 kg (26 lb) — matters for moving or storing it.
• You're comfortable managing a live fire — loading wood or charcoal and tending it through the bake.

Where they differ

Fuel

The Koda 2 is a single-fuel propane oven: gas in, no other option, and the burner is part of the oven rather than a separate accessory. The Karu 12 is Ooni's multi-fuel design — it burns wood or charcoal out of the box, and a gas burner attachment exists for it but is sold separately, so running the Karu 12 on gas is an added purchase, not something it ships with.

That split is also a split in how each oven is run: the Koda 2's propane burner lights and shuts off with a dial, while the Karu 12's wood or charcoal needs to be loaded and the fire tended through the bake.

It's also a split in what you have to keep on hand. The Koda 2 needs a propane tank, refilled or exchanged like any other gas appliance. The Karu 12 needs a supply of wood or charcoal, which is a different kind of restocking question — more like keeping a grill stocked than keeping a gas tank full — and it's worth thinking through before the fuel choice rather than after, since it isn't something the Karu 12's optional gas burner changes unless you've also bought that attachment.

Pizza size

The Koda 2 takes pizzas up to 14 inches; the Karu 12 takes pizzas up to 12 inches, a 2-inch difference in deck size between the two. Like the fuel split, this is a fixed property of each oven rather than something technique changes — the Karu 12's deck doesn't grow if you switch it to gas, and the Koda 2's doesn't shrink if you cook something other than pizza on it.

Two inches is a modest gap next to the fuel question, so if wood or charcoal versus propane is already decided for you, pizza size is unlikely to be the thing that changes your mind back the other way. It matters more if you're choosing between these two on size alone and fuel is genuinely open either way.

Weight and footprint

The Karu 12 is the lighter of the two at 12 kg (26 lb), against the Koda 2's 16 kg (35 lb). Footprint doesn't follow the same pattern: the Koda 2's published footprint is 54.5 x 47.2 x 33.3 cm, while the Karu 12's is 40 x 80 x 77 cm — narrower across the front than the Koda 2, but considerably deeper and taller. Judge the two by the shape of the space you have rather than by weight alone.

The Karu 12's extra height and depth are worth measuring against wherever you plan to put it — a spot that comfortably fits the Koda 2's 33.3 cm height may not clear the Karu 12's 77 cm height, regardless of which oven is lighter to carry there.

Published maximum temperature

Ooni rates the Koda 2 to 510 °C (950 °F) and the Karu 12 to 500 °C (932 °F), a 10 °C (18 °F) gap in the gas oven's favor. Both are well above a domestic kitchen oven's typical 250–290 °C (480–555 °F) ceiling, and the gap between the two Ooni ovens is small next to that.

What neither tells you

Ooni doesn't publish a maximum floor temperature for either oven, so that figure isn't available to compare at all.

Preheat time is published for only one of the two: Ooni states the Karu 12 reaches its working temperature in about 15 minutes. No equivalent figure is published for the Koda 2, so there's nothing on its spec sheet to set that 15-minute figure against — a gap in what's published, not a claim that one oven preheats faster than the other.

Both ovens sit on the outdoor pizza oven hub alongside the rest of the gas and wood-fired lineup, if fuel type or size still leaves you between more than these two. Whichever one you bake on, if leopard spotting isn't showing up on the crust, no leopard spots on pizza crust covers what that char pattern actually needs — a floor around 400 °C (750 °F) and a well-fermented dough.
