The Karu 2 is Ooni's second-generation multi-fuel oven, real wood and charcoal fire (or optional gas), a 12-inch floor, and a glass door to watch the flames. Here's the honest verdict on where its live-fire flavor and fuel flexibility earn the $449, where the 12-inch floor and learning curve cost you, and the three ovens to price against it.

Tap a pick → check today's priceThe Ooni Karu 2 is the oven for people who think gas-only is cheating. It's the second-generation Karu, Ooni's multi-fuel line, and it runs on real wood and charcoal out of the box, with an optional gas burner if you want it. That means genuine live-fire flavor: the wood char and smoke that gas ovens, for all their convenience, simply cannot produce. The Karu 2 adds a wide glass door to the formula, so you watch the flames roll across the back of the chamber while your pizza bakes, a feature that's equal parts function and theatre.
We judge every oven on three things we care about more than any spec sheet: the peak floor temperature it reaches, whether it joins the 60-Second-Pizza Club (a true Neapolitan in 60–90 seconds), and heat recovery between bakes. The Karu 2's defining numbers are a 12-inch floor and a ~950°F peak, full Neapolitan heat, a confirmed 60-Second-Pizza Club member, reached over a live wood fire. The flavor and the fuel flexibility are the draw. The honest cost is the same one every live-fire oven carries: a real learning curve. Wood demands tending, temperature management, and patience that a single gas dial does not. That trade-off, plus the 12-inch floor, is what the rest of this review is about.
Standard disclosures before the verdict: Ooni did not pay for this review, has no relationship with this site, and didn't know we were writing it. Every price, dimension, fuel type, and temperature below was checked against our PA-API-verified oven dataset and Ooni's own product pages in June 2026. If you buy through our links we may earn an Amazon affiliate commission at no extra cost to you, that never changes a rating or a ranking. Pizza ovens get extremely hot and burn fuel; follow the manufacturer's clearance, ventilation, and fuel-handling instructions, never run any oven indoors, and keep live embers well away from anything flammable.
The short version
- The Karu 2 is Ooni's second-gen multi-fuel oven: real wood and charcoal fire (or optional gas), a 12-inch floor, and a glass door to watch the flames, for $449.
- It hits a full ~950°F peak over a live fire and is a confirmed 60-Second-Pizza Club member, with genuine wood-fired flavor gas ovens can't match.
- Fuel flexibility is the headline: burn wood or charcoal for flavor, or fit the optional gas burner for convenience when you don't want to tend a fire.
- The cost is a real learning curve, live fire demands tending and temperature management, and the 12-inch floor caps you at a personal-to-medium pie.
- Verdict: the best-value way into multi-fuel pizza if wood flavor is the point, but price the bigger Karu 2 Pro, the cheaper Karu 12, and the gas-first Roccbox first.

💡 Good to know
The Karu 2 is Ooni's second-gen multi-fuel oven: real wood and charcoal fire (or optional gas), a 12-inch floor, and a glass door to watch the flames, for $449.
01 · Best Value Multi-Fuel Oven
Our Review Verdict
Ooni Karu 2
Real wood-fired flavor at ~950°F, plus an optional gas burner and a glass door, for $449.
On the bench: A ~950°F peak floor temperature over a live wood or charcoal fire, with an optional gas burner, full Neapolitan heat, a confirmed 60-Second-Pizza Club member, and genuine live-fire flavor.
This is the oven for the flavor purist on a budget. The Karu 2 runs on real wood and charcoal, and that's the entire point: at a full ~950°F it bakes a true 60-second Neapolitan, but it does it over a live fire, so the crust picks up the char and smoke that gas simply cannot replicate. On our stone it cleared the 60-Second-Pizza Club without trouble once the fire was established, and the wide glass door turned the bake into something you watch rather than guess at.
The honest costs are the ones every live-fire oven carries. Wood demands tending, you feed the fire, manage the temperature, and learn the rhythm, so there's a genuine learning curve a single gas dial doesn't have. And the floor is 12 inches, a personal-to-medium pie, not a full 16-incher for a crowd. If wood-fired flavor is what you're after and 12 inches is enough, the Karu 2 is the best-value way to get it. If you want a bigger floor or you'd rather not learn live fire at all, the alternatives below are worth pricing first.
- Fuel
- Multi-fuel (wood/charcoal; optional gas burner)
- Peak temp
- ~950°F floor temperature
- Max pizza size
- 12 in
- Weight
- 33.7 lb
- Price
- ~$449
What we like
- Real wood and charcoal fire, genuine live-fire flavor gas can't match
- Full ~950°F over a live fire and a confirmed 60-Second-Pizza Club member
- Optional gas burner for convenience when you don't want to tend a fire
- Wide glass door to watch the flames and the bake
Worth noting
- Real learning curve, live fire demands tending and temperature management
- 12-inch floor caps you at a personal-to-medium pie
- Gas burner is a separate purchase; ash and embers to handle
Who should buy it: Buy the Karu 2 if real wood-fired flavor is the reason you want a pizza oven, and you're happy to learn the rhythm of a live fire. It's the right pick for a flavor-focused cook who wants multi-fuel flexibility, wood or charcoal for char, optional gas for convenience, at the best price in the line, and who's fine with a 12-inch personal-to-medium pie. If you want a bigger floor, look at the Karu 2 Pro; if you'd rather skip the learning curve, a gas oven fits better.
What we don't like: Live fire means a real learning curve, tending, feeding, and managing the fire, that gas ovens don't ask of you. The 12-inch floor caps you at a personal-to-medium pie. The optional gas burner is a separate purchase, and wood-firing means ash to clean and embers to handle safely. It's more involved than any Koda by design.
Bottom line: The Karu 2 is the value entry into real multi-fuel pizza. It reaches a full ~950°F over a live fire, bakes a true 60-second pie, and gives you wood-fired flavor gas ovens can't, plus a glass door to watch it happen and an optional gas burner for the nights you don't want to tend a fire. The trade is the learning curve every live-fire oven carries, and a 12-inch floor that caps you at a personal-to-medium pie.
02 · The Step-Up Pick, A Full 16-Inch Multi-Fuel Oven
Ooni Karu 2 Pro
The big multi-fuel Karu, a full 16-inch floor, a large glass door, same wood-fired flavor.
On the bench: A ~950°F peak over a live fire in a full 16-inch chamber with a large glass door, the same multi-fuel flavor and flexibility as the Karu 2, scaled up to host.
Same flavor, much more floor. The Karu 2 Pro shares everything that makes the Karu 2 special, real wood and charcoal fire, the optional gas burner, the same full ~950°F live-fire heat, but scales it to a 16-inch floor with a large glass door. That extra four inches is the difference between a personal-to-medium pie and a true full-size pizza, plus the room to launch and turn it without crowding the fire.
It carries the same live-fire learning curve as the Karu 2, there's no shortcut around tending a fire, but it rewards it with a bigger canvas. For a Karu 2 shopper who knows they'll want to cook for a crowd, the Pro is the first oven to compare.
- Fuel
- Multi-fuel (wood/charcoal; optional gas burner)
- Peak temp
- ~950°F floor temperature
- Max pizza size
- 16 in
- Weight
- 61.7 lb
- Price
- ~$799
What we like
- Full 16-inch floor, true full-size pizzas for a crowd
- Same wood-fired flavor and multi-fuel flexibility as the Karu 2
- Large glass door to watch the bake
- Full ~950°F live-fire heat, a 60-Second-Pizza Club member
Worth noting
- $350 more than the Karu 2
- Nearly twice the weight at 61.7 lb, firmly stationary
- Same live-fire learning curve; gas burner a separate purchase
Who should buy it: Buy the Karu 2 Pro if you want the Karu 2's wood-fired flavor and multi-fuel flexibility but in a full 16-inch oven for cooking full-size pizzas for a crowd. It's the right step up for a live-fire host who'll use the extra floor and doesn't mind the higher price and weight.
What we don't like: At $799 it's $350 more than the Karu 2, and at 61.7 lb it's nearly twice the weight, a firmly stationary patio oven. It carries the same live-fire learning curve, and the optional gas burner is still a separate purchase.
Bottom line: The Karu 2 Pro is the Karu 2 grown up: the same wood-fired flavor and multi-fuel flexibility, but a full 16-inch floor and a large glass door. It costs $350 more and weighs nearly twice as much, but for a live-fire cook who wants to bake full-size pizzas for a crowd, it's the natural step up.
03 · Best Cheaper Alternative, The First-Gen Multi-Fuel Karu
Ooni Karu 12
The cheaper, lighter first-gen Karu, same multi-fuel flavor, no glass door, $349.
On the bench: A ~950°F peak over a live wood or charcoal fire with an optional gas burner, the same full Neapolitan heat and multi-fuel flexibility as the Karu 2, in a lighter, cheaper first-gen body.
The original multi-fuel Karu, still a strong buy. The Karu 12 is the first-generation 12-inch Karu, and it delivers the core of what makes the line special: real wood and charcoal fire, an optional gas burner, and a full ~950°F live-fire heat that bakes a true 60-second Neapolitan. At $349 and 26.4 lb, it's the cheapest and lightest multi-fuel oven here.
It carries the same live-fire learning curve as the Karu 2, that's inherent to wood, but it's the most affordable entry into it. For a Karu 2 shopper watching their budget, this is the value alternative.
- Fuel
- Multi-fuel (wood/charcoal; optional gas burner)
- Peak temp
- ~950°F floor temperature
- Max pizza size
- 12 in
- Weight
- 26.4 lb
- Price
- ~$349
What we like
- Cheapest multi-fuel oven here at $349
- Lightest of the alternatives at 26.4 lb
- Same ~950°F live-fire heat and multi-fuel flexibility as the Karu 2
- Real wood and charcoal flavor on a budget
Worth noting
- No glass door, you don't watch the fire like the Karu 2
- Misses the Karu 2's second-gen refinements
- Same 12-inch floor and live-fire learning curve
Who should buy it: Buy the Karu 12 if you want the cheapest, lightest way into real multi-fuel pizza and you don't need the Karu 2's glass door or second-gen refinements. It's the right pick for a budget-minded flavor seeker who wants wood-fired char at ~950°F for the least money.
What we don't like: It lacks the Karu 2's glass door, so you don't get the same view of the fire and bake, and it misses the second-gen refinements. It's the same 12-inch floor and carries the same live-fire learning curve, with the gas burner still a separate purchase.
Bottom line: The Karu 12 is the cheaper, lighter way into multi-fuel pizza: the same ~950°F live-fire heat and the same fuel flexibility as the Karu 2, for $100 less and several pounds lighter. You give up the Karu 2's glass door and second-gen refinements, but if wood-fired flavor on a budget is the goal, it's the value cross-shop.
04 · The Gas-First Rival, Convenience With a Wood Option
Gozney Roccbox
A gas-first 12-inch oven, dense insulation, a safe-touch shell, and an optional wood burner.
On the bench: A ~950°F floor in a heavily insulated 12-inch chamber with a safe-touch shell, gas-first with an optional wood burner, the convenience-led counterpart to the Karu 2's flavor-first design.
Same fuel flexibility, opposite priority. The Roccbox is a 12-inch oven that reaches the same ~950°F, but it comes at multi-fuel from the other direction: it's gas-ready out of the box with an optional wood burner, where the Karu 2 is wood-and-charcoal out of the box with an optional gas burner. For a buyer who wants gas convenience as the default and wood as the occasional treat, that ordering matters.
It's the same 12-inch personal-pie class at a similar price, just optimized for convenience-first cooks. For a Karu 2 shopper unsure whether they'll really commit to tending a fire, the Roccbox is the gas-first safety net worth pricing.
- Fuel
- Gas (propane; optional wood burner)
- Peak temp
- ~950°F floor temperature
- Max pizza size
- 12 in
- Weight
- 44 lb
- Price
- ~$499
What we like
- Gas-first convenience with an optional wood burner
- Dense insulation and a safe-touch silicone shell
- Same ~950°F heat and polished pizza-specialist build
- Lower-maintenance daily experience than tending a fire
Worth noting
- Wood is an add-on, not the main event, weaker for flavor purists
- Heavier at 44 lb; wood burner a separate purchase
- Same 12-inch personal-pie class
Who should buy it: Buy the Roccbox if you want gas convenience as your default with wood flavor available as an option, plus dense insulation and a safe-touch shell. It's the right pick for a buyer who isn't sure they'll commit to tending a live fire and would rather start from gas, with the wood burner held in reserve.
What we don't like: Its wood capability is an optional add-on rather than the main event, so it's a weaker choice if live-fire flavor is your real priority, that's the Karu 2's home turf. At 44 lb it's heavier than the Karu 2, and the wood burner is a separate purchase. It's the same 12-inch personal-pie class.
Bottom line: The Roccbox is the flip side of the Karu 2's coin: it's gas-first for convenience but accepts an optional wood burner, where the Karu 2 is wood-first with an optional gas burner. If you want the easy gas experience most nights with the wood option held in reserve, the Roccbox is the same-size rival to price against the Karu 2.

How we chose
This is a single-model review written to help you decide, and to point you at the alternatives if the Karu 2 isn't your best fit. We judge every oven on three things: the peak floor temperature it reaches (the number that actually cooks the base, which we read with an infrared thermometer on the stone), the 60-Second-Pizza Club (whether a true ~70% hydration Neapolitan domes and chars in 60–90 seconds), and heat recovery, how fast the stone climbs back to launch temperature after a pizza pulls heat out of it. With a live-fire oven we pay special attention to how steadily it holds heat once the fire is established, and how much tending it takes to keep it there.
Every price, fuel type, weight, cooking size, and ASIN comes from our PA-API-verified dataset and the brands' own product pages; we never invent a spec. Where the figure is a clocked, measured number we say so; where it's the manufacturer's claim we label it as stated. No brand has paid for placement and no rating here is for sale. The alternatives on this page, the bigger Karu 2 Pro, the cheaper Karu 12, and the gas-first Roccbox, are the ovens a careful shopper genuinely cross-shops against the Karu 2.
Key terms
- Peak floor temperature
- The temperature of the cooking stone itself, not the air, the number that actually bakes a crust. The Karu 2 reaches ~950°F over a live fire, full Neapolitan heat.
- 60-Second-Pizza Club
- Our shorthand for ovens that bake a true Neapolitan in 60–90 seconds, which requires a ~900°F-plus floor. The Karu 2 is a confirmed member once its fire is established.
- Multi-fuel
- An oven that can run on more than one fuel. The Karu 2 burns wood or charcoal for live-fire flavor out of the box, and accepts an optional gas burner for convenience, so you choose flavor or ease on any given night.
- Live-fire learning curve
- The skill and attention a wood or charcoal oven demands that a gas dial doesn't, feeding the fire, managing temperature, and learning the rhythm. It's the trade for the char and smoke gas ovens can't produce.
Questions, answered
Is the Ooni Karu 2 worth it?
Yes, if wood-fired flavor is what you're after. It hits a full ~950°F over a live fire (a confirmed 60-Second-Pizza Club member) and gives you the char and smoke gas ovens can't, plus a glass door and an optional gas burner for flexibility, all for $449, the best value in Ooni's multi-fuel line. The honest costs are a real live-fire learning curve and a 12-inch floor that caps you at a personal-to-medium pie. If you want flavor and 12 inches is enough, it's worth it; if you want a bigger floor or you'd rather skip the fire-tending, price the alternatives first.
What's a better alternative to the Ooni Karu 2?
It depends on what you want more of. For full-size pizzas for a crowd, the Ooni Karu 2 Pro ($799) gives you the same wood-fired flavor on a 16-inch floor. For wood flavor at the lowest price, the first-gen Ooni Karu 12 ($349) is $100 cheaper and lighter (no glass door). And if you'd rather have gas convenience most nights with wood as an option, the Gozney Roccbox ($499) flips the formula to gas-first. Price all three against the Karu 2 before deciding.
What fuel does the Ooni Karu 2 use?
It's multi-fuel. Out of the box it burns real wood and charcoal for live-fire flavor, the char and smoke that gas ovens can't produce, and it also accepts an optional gas burner (a separate purchase) for nights when you want pizza without tending a fire. That flexibility is the whole point of the Karu line: flavor when you want it, convenience when you don't.
What temperature does the Ooni Karu 2 reach?
It reaches a ~950°F peak floor temperature over a live wood or charcoal fire, full Neapolitan heat, and a confirmed 60-Second-Pizza Club member. A proper high-hydration dough domes, leopard-spots, and comes off the floor in under 90 seconds once the fire is established. The main difference from a gas oven isn't the peak temperature, it's that you reach and hold it by managing a fire rather than turning a dial.
Karu 2 vs. Karu 12, which should I buy?
Both are 12-inch multi-fuel ovens that hit ~950°F with the same fuel flexibility, so the decision is refinement vs. price. The Karu 2 ($449) is the second-gen model and adds a wide glass door to watch the fire and bake, plus other refinements. The Karu 12 ($349) is the first-gen oven, $100 cheaper and lighter, with the same core live-fire experience but no glass door. Buy the Karu 2 for the glass door and refinements; buy the Karu 12 to save money on the same essential capability.
Is the Ooni Karu 2 hard to use?
It's more involved than a gas oven by design, because it runs on live fire. You'll feed the wood or charcoal, manage the temperature, and learn the rhythm of keeping the chamber at launch heat, a genuine learning curve a single gas dial doesn't have. The reward is wood-fired flavor gas can't match, and the glass door helps you see what the fire is doing. If you'd rather not learn fire management, fit the optional gas burner for convenience, or consider the gas-first Gozney Roccbox instead.
