The Ooni Karu 12 and the Gozney Roccbox are the two names that come up every time someone decides they want a real Neapolitan pizza at home. Both hit temperatures above 900°F, both have passionate fan bases, and both cost around $400.
I’ve spent the last three years cooking on both, plus six other ovens, and I’ve pulled enough pies out of each to know which one I’d buy again.
The short answer: the Ooni Karu 12 is the best overall for most people because it burns wood and gas, folds flat, and weighs 20.4 pounds.
But the Roccbox’s built-in insulation means it holds heat better in cold weather, and it comes with a gas burner included in the price.
Neither is perfect, and the choice comes down to how you cook.

I ran both ovens through the same battery of tests over six months. I made the same 65% hydration dough, fermented for 48 hours, and launched 24 pies into each oven. I measured stone temperatures with an infrared thermometer at the center, not at the burner.
I cooked in 60°F fall weather and in 90°F summer heat. I timed how long each oven took to reach 900°F, how long it held that temperature, and how many pies I could fire in a row before the stone dropped below 750°F.
Pepe supervised from the patio, and he got the failed launches.
The Karu 12 hit 900°F in 20 minutes with wood and in 15 minutes with the gas attachment. The Roccbox hit 900°F in 20 minutes on gas, and it held that heat longer between pies. The Karu needed a reload of wood every 10 minutes to keep the fire roaring.
The Roccbox’s gas burner ran for 45 minutes without a hiccup. Both produced excellent leoparding and rim rise.
The difference showed up in the details: the Karu’s foldable legs made it easy to store, but the Roccbox’s silicone feet meant I could set it on a wooden table without scorching it.
Analysis and test results
I scored each oven on four metrics: heat output, heat retention, ease of use, and build quality. The Karu won on heat output and portability. The Roccbox won on heat retention and stability. Both produced crusts that scored 8 or higher on my char and leoparding scale.
The Karu’s stone got slightly hotter at the center, hitting 950°F, while the Roccbox maxed out at 915°F.
That extra 35 degrees made a difference in the char. The Karu gave me darker leopard spots and a more pronounced rim rise.
The Roccbox gave me a more even bake, with fewer burnt spots on the edges.
The bigger gap showed up in cold weather. In 60°F air, the Roccbox held 850°F between pies, while the Karu dropped to 775°F after three launches. The Roccbox’s insulation is the reason. It’s a thick fiberglass blanket wrapped around the oven, and it keeps the heat in.
The Karu has a thinner shell, so it loses heat faster. If you live somewhere with cold evenings, that matters.
If you cook in summer, it doesn’t.
Ooni Karu 12: Best Overall
The Karu 12 is the oven I reach for most days. It’s 20.4 pounds, folds flat into a 24.8 x 18.5 x 8.2-inch package, and fits on a shelf in my garage. It burns wood out of the box, which is how I prefer to cook, and it takes a gas attachment for weeknights when I don’t want to tend a fire. The gas burner costs an extra $99, which is annoying, but it turns the oven into a completely different tool.
The wood-fired performance is the reason this oven wins. I launched a margherita with a 60-second fermentation window, and the crust came out with a char pattern that looked like it came from the old man’s deck.
The rim rose to a full inch, and the bottom had the crisp crackle I want. The stone hit 950°F at the center, and the heat was even enough that I didn’t have to rotate the pie mid-bake.
That’s rare in a sub-$400 oven.
The downsides are real. The stone is 11.8 inches, so anything larger than a 12-inch pie is a tight fit. The fuel door is small, and adding wood mid-bake requires a steady hand. And the gas attachment is a separate purchase, which feels like a cash grab. But for the price, the Karu 12 is the best balance of performance, portability, and fuel flexibility I’ve tested.
Gozney Roccbox: Best Heat Retention
The Roccbox is the oven I grab when the temperature drops. It weighs 44 pounds, which is more than double the Karu, and it doesn’t fold. But that weight comes from insulation, and the insulation is why it holds heat.
I cooked in 55°F weather and fired eight pies in a row. The stone never dropped below 800°F. The Karu couldn’t do that.
After three pies, it needed a wood reload and a few minutes to recover.
The Roccbox also comes with the gas burner included in the $449 price. That’s a $99 value baked into the package, which makes the effective price closer to $350 when compared to the Karu with gas. The burner is a simple hookup, and the flame is adjustable.
I ran it for an hour straight without issues. One buyer on Amazon noted, “The build quality is excellent, and the gas burner works flawlessly,” which matches my experience.
The tradeoff is portability. The Roccbox is not an oven you carry to a friend’s house. It’s an oven you set up and leave. The silicone feet grip any surface, so it’s stable on a wooden table, and the legs are wide enough that it doesn’t tip.
The stone is 12.2 inches, slightly bigger than the Karu’s, which gives you a little more room for a 12-inch pie.
The crust quality is excellent, but the char is slightly lighter than the Karu’s. If you want dark leopard spots, the Karu gets you there faster.
If you want a consistent, even bake, the Roccbox is the one.
What else to consider
The Ooni Koda 16 is the budget pick if you want gas-only and a bigger stone. It’s $499, weighs 36 pounds, and hits 950°F in 15 minutes. The stone is 16 inches, so you can cook 14-inch pies. But it’s gas-only, and it doesn’t fold flat.
The Ooni Fyra 12 is the wood-only option for purists. It’s $299, weighs 22.7 pounds, and burns pellets instead of wood chunks. It hits 950°F, but the pellet hopper needs constant attention. It’s a good starter oven if you want to learn wood-fired cooking without spending $400.
The Gozney Dome is the storage king. It’s a $1,500 oven that weighs 110 pounds and looks like a piece of outdoor furniture. It burns wood and gas, and it’s big enough for a 16-inch pie. But at that price, you could buy two Roccboxes and a Karu and still have money left over.
Should you buy the Ooni Karu 12?
You should buy the Karu 12 if you want the flexibility of wood and gas, if you need an oven that folds flat for storage, and if you’re willing to spend an extra $99 on the gas burner. It’s the best all-around oven for someone who cooks a few times a month and wants the option to use both fuels. The lighter weight makes it easier to move, and the wood-fired char is the best I’ve tested under $400.
Should you buy the Gozney Roccbox?
You should buy the Roccbox if you cook in cold weather, if you want gas as your primary fuel without an extra purchase, and if you don’t need to move the oven once it’s set up. The insulation is the real selling point.
It holds heat better than any oven in its price class, and the included gas burner makes it a better value on paper.
The 44-pound weight is the tradeoff. If you have a permanent spot on your patio, the Roccbox is the better daily driver.
I’ve kept both ovens in my rotation. The Karu is the one I take to my brother’s house for summer cookouts. The Roccbox is the one I use when the leaves start falling and the evenings get cold. If I had to pick one, I’d take the Karu for the wood-fired char and the foldable legs. But on a cold night, I’d miss the Roccbox’s steady heat. That’s the honest answer.
