“Ooni Karu vs Ninja Woodfire” is the comparison people search for, and it is two different kinds of oven. The Ooni Karu burns real wood or charcoal. The Ninja Woodfire is an electric oven with a small box of wood pellets for smoke. Both say wood on the box, and both make good pizza, but one asks you to tend a fire and the other asks for an outlet.
So this page splits them the way the choice actually splits: do you want to cook on fire, or plug in? In each lane we name the best oven, and in each lane we name the popular one to skip. We read all seven listings signed in on the same day with their recent critical reviews, read each maker’s warranty in its own words, and checked every tester’s quote on the tester’s own page.
This is a Catchweight showdown — compared by fuel, not price. The gas-only ovens (Ooni Koda, Gozney Roccbox and Arc) have their own division ladder.
The short version:
🏆 Best wood-fired: Ooni Karu 2 — a 12 in oven that burns wood or charcoal, tested at a 750°F stone in 10–12 minutes, with a glass door and a five-year registered warranty. Gas is a paid extra.
🔌 Best electric: Ninja Artisan — plug in, pick a crust preset, walk away. 700°F, no smoke, and the best owner rating on the page.
💰 Wood-fired value pick: Ooni Karu 12 — the first-generation Karu, marked down, with no door glass and no thermometer.
🍕 Big-pie pick: Ooni Karu 2 Pro — the only 16 in oven here, measured at a 760°F stone on wood and on gas.
💨 Electric with smoke pick: Ninja Woodfire — the plug-in oven that also smokes, with a lifespan record you should read first.
⛔ Skip: Ooni Volt 2 — indoor use only, by Ooni’s own page, and the owners’ most common complaint is a cracked stone.
⛔ Skip: BIG HORN 12 in pellet oven — Amazon’s best seller, untested by anyone credentialed, and its maker’s warranty excludes Amazon purchases.

The max temperature column is the maker’s claim, and the one below is not. Here is what testers actually measured, and what each number is a temperature of — the stone, which is what cooks the base, or the air:
| Oven | What was measured | Result | Tester |
|---|---|---|---|
| Ooni Karu 2 Pro | Stone, wood / propane | 760.4°F / 759.4°F | America’s Test Kitchen |
| Ooni Karu 2 | Stone, average | 825°F, 1.8-minute bakes | TechGearLab |
| Ooni Karu 2 | Stone, charcoal and wood | 750°F in 10–12 min | Tom’s Guide |
| Ninja Artisan | Oven setting | 700°F in 18–20 min | Tom’s Guide |
| Ooni Volt 2 | Oven setting | 850°F in 25 min | Engadget |
| Ninja Woodfire | — | No stone reading published | — |
| BIG HORN 12 in | — | No credentialed test | — |
The gauges read the air, not the stone. Tom’s Guide says the Karu 2’s gauge only measures ambient temperature, and the Karu 2 Pro’s Bluetooth hub reads the air too. The stone is what bakes the base, so budget for an infrared thermometer with any of the Ooni ovens.
Is the Ninja Woodfire really wood-fired?
No, and Ninja does not claim otherwise in the small print: the pellets are for flavor, not fuel. The oven heats with a 120 V element, like the Artisan. The Woodfire adds a small box on the side where a half cup of pellets smolders and the smoke is drawn through.
Whether that smoke reaches a pizza is the question, and the testers’ answer is: barely. Reviewed.com “didn’t notice an intense smoke flavor in quick-cooking food like pizza or seared pork chops” and recommends the box for longer cooks, where it found “a smoke presence that was just as aromatic and vibrant as when we’ve cooked chickens on a dedicated smoker.” A pizza is in and out in about three minutes.
The twist is that real wood does not flavor a pizza much either. It bakes too fast. A Karu 12 owner who switched from charcoal to the gas burner wrote: “Once I hooked up propane, it was cleaner and way faster and I could not tell the difference in taste.” What a wood fire gives you is heat — the stone temperatures above — and the part of making pizza that many people buy one of these for: cooking on a fire.
So choose on that. If you want to tend a fire, buy a Karu. If you want the pizza and not the fire, buy an electric. And if you want smoked chicken as well as pizza from one box, that is the case for the Woodfire.
Best wood-fired: Ooni Karu 2
A 12 in oven that burns wood or charcoal, with a glass door, folding legs and 33.7 lb to carry. It is the tested favorite of this class: Tom’s Guide measured its stone at 750°F in 10–12 minutes on charcoal and wood and wrote that it “makes tasty pies worthy of a restaurant or pizzeria,” and TechGearLab scored it 83 out of 100 with an 825°F average stone. It is the Karu that used to be called the 12G.
On Amazon it is sold by Ooni itself at $449, with 4.5 stars from 215 owners and 12 critical reviews. Ooni’s warranty is one year, or five if you register within 60 days, and the text has no retailer restriction — the only Ooni limit is that you live in a region it ships to.
Not for you if you want gas in the box, or a fire you can ignore. “Multi-fuel” means wood and charcoal until you buy Ooni’s gas burner, and that is what the critical reviews say first. A live fire needs feeding every few minutes, and the heat moves with it — Tom’s Guide’s own con is that you’ll need to stay on top of temperature. An owner’s version: “it is a little bit hard to regulate the temperature and get it hot enough.” One owner reports a cracked stone and a door that stopped closing inside eight months.

Pro review “The Ooni Karu 2 is a versatile pizza oven that makes tasty pies worthy of a restaurant or pizzeria.”— Peter Wolinski, Tom's Guide
- Burns wood or charcoal out of the box, and takes Ooni's gas burner if you want it later
- Tested at a 750°F stone in 10–12 minutes (Tom's Guide) and an 825°F average (TechGearLab)
- Glass door, so you watch the pie without letting the heat out
- Five-year warranty if you register it within 60 days, with no retailer restriction in the text
- Sold on Amazon by Ooni itself
- 'Multi-fuel' ships wood-and-charcoal only — the gas burner is $120 more
- A live fire needs feeding every few minutes, and the heat swings with it
- The gauge reads the air, not the stone, so you need an infrared thermometer
- Owners report a cracked stone and a door that stopped closing inside a year
What 'multi-fuel' means — owners expected gas in the box and found the burner sold separately — then fire management and build: a cracked stone, a door that stopped closing, and heat that is hard to hold on wood.

Best electric: Ninja Artisan
An electric oven that happens to live outside. It preheats to 700°F in 18 to 20 minutes, then you pick a crust preset — Neapolitan, New York, pan, thin or custom — slide the pie in and shut the door. It also bakes, broils, warms and proofs dough. Tom’s Guide’s verdict: “The NInja Artisan Outdoor Pizza Oven delivers fast, hot, bubbling pies, though it’s missing wood smoke flavor.” (The typo is theirs.)
It has the best owner rating on this page, 4.7 stars from 509, and the smallest share of critical reviews of the three electrics. It is sold and shipped by Amazon at $300, which matters because SharkNinja’s one-year warranty “applies to purchases made from authorized retailers.” It is also Amazon’s number-two outdoor oven.
Not for you if you want Neapolitan char or any smoke. 700°F makes a good pizza in about three minutes; it is not the 900°F-and-90-seconds style. It needs an outdoor outlet. The critical reviews are about cleaning — toppings bake onto the stone and the cavity — and two owners report a door or hinge that broke within a few months.
Ninja Artisan Outdoor Pizza Oven (MO201)
Best electric ovenYour pick if you want pizza night without a fire — plug in, pick a crust preset, walk away — from the oven Tom's Guide calls fast and hands-off at 4.7★; you accept 700°F rather than 900°F and no smoke at all.
“It was also surprisingly easy to set up and figure out right away. There wasn’t a big learning curve — we were able to start making pizza pretty much immediately.”— Verified Purchase owner, Amazon · Verified owner
Pro review “The NInja Artisan Outdoor Pizza Oven delivers fast, hot, bubbling pies, though it’s missing wood smoke flavor.”— Kelly Woo, Tom's Guide
- No fuel to buy or tend — plug it in and pick a crust preset
- Tom's Guide: 18–20 minutes to 700°F, then it holds steady
- Bakes, broils, warms and proofs dough as well as pizza
- Sold and shipped by Amazon itself, which settles the authorized-retailer question
- Tops out at 700°F — hot enough for good pizza, short of the 900°F Neapolitan crowd
- No smoke flavor of any kind
- Needs an outdoor outlet — there is no battery or fuel option
- Owners find it hard to clean, and two report a door or hinge that broke
Cleaning — toppings bake onto the stone and the cavity — and two owners whose door or hinge broke within a few months. The rest is learning the launch.

Wood-fired value pick: Ooni Karu 12
The first-generation Karu, still sold by Ooni and marked down to $249 from $349. It burns the same wood and charcoal, takes the same gas burner as the Karu 2, and carries the same five-year registered warranty. It has the deepest owner record of the Karu line: 4.6 stars from 650.
What you give up is the door glass and any thermometer at all, and Tom’s Guide says it burns fuel a little quicker than the Karu 2. America’s Test Kitchen still lists it as Highly Recommended.
Not for you if you do not own an infrared thermometer. With no gauge of any kind, you cannot tell when the stone is ready. The critical reviews add the same gas-burner surprise as the Karu 2, and one owner whose oven never got near the advertised 950°F.
Ooni Karu 12 Multi-Fuel Pizza Oven (1st Generation)
Wood-fired value pickYour pick if you want a real wood-fired oven for the least money from a maker that stands behind it — the deepest owner record of the current Karu line, at 4.6★ — and you are fine with no door glass and no thermometer.
“Love this oven. I highly recommend that you buy the external propane connection. I tried cooking pizza pizzas with the Uni charcoal, and it was quite messy and it took a long time to get the oven up to temperature. Once I hooked up propane, it was cleaner and way faster and I could not tell the difference in taste.”— Verified Purchase owner, Amazon · Verified owner
- The cheapest way into a real wood or charcoal oven from Ooni, marked down from $349
- The deepest owner base of the current Karu line, at 650 ratings
- Same five-year registered warranty as the Karu 2
- Lightest here at 26.4 lb
- No thermometer of any kind — you need an infrared gun from day one
- No glass door, and Tom's Guide says it burns fuel a little quicker than the Karu 2
- Gas is a $120 add-on, and several owners bought it expecting gas in the box
- Owners report the folding legs tip easily during assembly
Missing expectations more than failures — the gas burner is not included, there is no thermometer, and one owner's oven never approached the advertised 950°F.

Big-pie pick: Ooni Karu 2 Pro
The 16 in Karu, which replaced the Karu 16. America’s Test Kitchen rated it Highly Recommended — “This large multifuel oven was easy to set up and a pleasure to use” — and measured its stone at 760.4°F on wood and 759.4°F on propane: the same heat either way, which is the point of a multi-fuel oven. It has a glass door and a Bluetooth hub, and sells for $849.
Not for you unless you need 16 in pies. It is the most expensive oven here before the gas burner, and four of the ten newest critical reviews say the same thing: “It’s not multi fuel. You have to purchase adapters to make it multi fuel.” A bigger fire also means more wood and more attention. One owner’s honest version: “The ideal of making pizza in a wood burning oven, sounds good - but may not necessarily translate for most users.”
Ooni Karu 2 Pro Multi-Fuel Pizza Oven
Big-pie wood-fired pickYour pick if you cook 14–16 in pies for a crowd and want the wood-fired oven America's Test Kitchen measured at a 760°F stone on both wood and gas; you accept paying $849 before the $140 gas burner.
“I love it, but it does take some time to understand how to use it. The ideal of making pizza in a wood burning oven, sounds good - but may not necessarily translate for most users.”— Verified Purchase owner, Amazon · Verified owner
Pro review “This large multifuel oven was easy to set up and a pleasure to use.”— America's Test Kitchen
- Takes a 16 in pizza, where the Karu 2 and Karu 12 take 12 in
- America's Test Kitchen measured the stone at 760°F on wood and on propane — the same heat either way
- Glass door and a Bluetooth temperature hub
- Five-year warranty on registration, with no retailer restriction in the text
- $849, and the gas burner is $140 more — four of the ten newest critical reviews say they expected it in the box
- The hub reads the air, not the stone
- Big enough that the fire takes more wood and more attention than the 12 in ovens
- Owners call it overpriced for the build
'Not multi-fuel out of the box' — the gas burner is sold separately, and four of the ten newest critical reviews say so. After that: price, and heat that drops after a few pies.

Electric with smoke pick: Ninja Woodfire
The Artisan’s sibling with a pellet smoke box, a taller cavity and eight functions — pizza, max roast, specialty roast, broil, bake, smoker, dehydrate and keep warm. Reviewed.com: “we can wholeheartedly recommend this to anyone who enjoys cooking outdoors.” It has 4.6 stars from 851 owners, every card we read from a US buyer, and is selling well under its list price at $295.
Read the critical reviews before you buy it. 77 of its 851 ratings are critical, the highest share of the electrics after the Volt 2, and five of the ten most recent describe a unit that stopped working: “I had three of them and they all died without warning, the last after barely 3 weeks,” “Buttons stop working after 3 months,” “Quit working after 18 months.” The warranty is one year and limited to SharkNinja’s authorized retailers; on Amazon the buy box was held by Woot the day we read it, with Amazon.com also selling it new. Tom’s Guide also found it does not get as hot as the Artisan.
If you want pizza, the Artisan is the better Ninja. If you want one box for pizza and a smoked chicken, this is the only one here that does both — buy it where a return is easy, and register it.
Ninja Woodfire Outdoor Oven (OO101)
Electric with smokeYour pick if you want one plug-in box that makes pizza and genuinely smokes a chicken, at 4.6★; you accept that the smoke barely reaches a three-minute pizza and that owners report the electronics dying, some just past the one-year warranty.
“I purchased the Ninja Pizza Oven/Smoker about two years ago, and it’s easily one of the best kitchen investments I’ve ever made. I was initially hesitant about whether I’d use it enough to justify the cost—but now, after making over 100 pizzas and smoking countless meals, I can say without a doubt that it was more than worth it.”— Verified Purchase owner, Amazon · Verified owner
Pro review “we can wholeheartedly recommend this to anyone who enjoys cooking outdoors.”— Lindsay D. Mattison, Reviewed
- Smokes, roasts and dehydrates as well as baking pizza
- Reviewed.com found real smoke on a 55-minute chicken
- A deep owner base, at 851 ratings, all from US buyers
- Selling well under its $399.99 list price
- Five of the ten newest critical reviews say it stopped working — at three weeks, three months, a year and 18 months
- One-year warranty, limited to SharkNinja's authorized retailers; the buy box on Amazon is Woot
- The smoke barely shows on pizza — Reviewed.com noticed no intense smoke flavor on a quick cook
- Tom's Guide: it does not get as hot as the Ninja Artisan
It stops working — dead controls or no power at three weeks, three months, a year and 18 months; one owner went through three. Then a small smoke box and a firebox handle that broke.

Skip: Ooni Volt 2
First, what it is not: an outdoor oven. Ooni’s own page answers “Can I use Volt 2 outdoors?” with “Volt 2 is suitable for indoor use only.” It is here because Ninja Artisan vs Ooni Volt is what people search when they want a plug-in oven, and if your plan is the patio, that settles it.
For a kitchen counter, the steelman is real: 850°F with no fire, and Engadget scored it 88 out of 100 — “There’s no sophomore slump here.”
The owners report something the testers did not. Its listing has 3.8 stars from 62 ratings, one in five of them a single star, and six of the ten newest critical reviews are the same failure: the pizza stone cracks — on arrival, on the first bake, or within three — and replacing it meant returning the oven. One owner went through three units: “the glass exploded during seasoning process.” At $699 for a 12 in oven, that is too high a rate of the one part that matters. Ooni’s three-year registered warranty would cover it; we would rather not need it.
Your pick if you want Neapolitan heat on a kitchen counter — Ooni rates it for indoor use only — from the oven testers rate highest; you accept paying $699 for an oven whose owners keep reporting the stone cracked in the box or on the first bake.
“The first oven I bought came in with the broken stone so I returned and got second one. Second ooni came in with big dent on a side and broken stone. I returned it and got the third one. Third one came in with broken handle, a dent on a side. In addition to it the glass exploded during seasoning process. I am done with Ooni at this point.”— Verified Purchase owner, Amazon · Verified owner
Pro review “There's no sophomore slump here.”— Billy Steele, Engadget
- 850°F on a kitchen counter, hotter than either Ninja
- Testers like it: Engadget scored it 88 out of 100
- Three-year warranty on registration
- Six of the ten newest critical reviews report a cracked stone — several on arrival or the first use
- One owner reports the door glass shattered during seasoning
- 3.8 stars, with one rating in five a single star
- $699 for a 12 in electric oven
- Indoor use only, per Ooni — it is not an outdoor oven
The pizza stone cracks — on arrival, on the first use or within three — and replacing it meant returning the whole oven. Also dents in the box and one shattered door glass.

Skip: BIG HORN 12 in Wood Pellet Pizza Oven
Amazon’s number-one outdoor oven, at $130, with 4.4 stars from 2,652 owners. The steelman: it is the cheapest way to find out whether you like making pizza on fire, and owners who stick with it love it. One of them, rating it five stars, still leads with the warning: “Beware-It absolutely has a learning curve on both the lighting and heat management.”
We skip it for three reasons. No credentialed outlet has tested it, so every temperature claim is the listing’s own, including 1,110°F. Owners report the opposite of that claim — pellets that fight you to light and heat that will not hold; one wrote “The stone never got hotter than 450.”* And the maker’s warranty does not cover the listing you would buy. BIG HORN’s own product page says “24 Months Warranty” and, under it, “Only valid on bighornoutdoor.com purchases.” The “3-in-1” in its sibling listing’s title means a gas burner and an electric element sold separately. The rating is also one pool across five colours and a bundle.
Your pick if you want to find out whether you even like making pizza for about $130, and you enjoy a project; you accept pellets that fight you to light, a stone owners say may never pass 450°F, and a maker whose warranty does not cover an Amazon purchase.
“Beware-It absolutely has a learning curve on both the lighting and heat management.”— Verified Purchase owner, Amazon · Verified owner
- About $130
- Amazon's #1 best-selling outdoor oven, with owners who love it once they learn it
- Light, at 24.9 lb
- BIG HORN's own site says its 24-month warranty is 'Only valid on bighornoutdoor.com purchases' — not Amazon
- Owners report pellets that are hard to light and heat that will not hold; one says the stone never passed 450°F
- The '3-in-1' gas burner and electric element are extra-cost parts
- No credentialed outlet has tested it
It will not get or stay hot — pellets hard to light, heat that drops, one stone that never passed 450°F — and the '3-in-1' parts are sold separately.

Read and not carded
PIZZELLO 16 in wood oven: 4.2 stars from 862, but one rating pooled across its 12 and 16 in sizes, no thermometer, and critical reviews about one side burning and a door that warps. Gozney Roccbox: a gas oven first; its wood burner is sold out on Gozney’s US store, so it stays in the gas division. Ooni Fyra 12: gone from Ooni’s US catalogue. Bertello’s new oven: pre-order only. Solo Stove Pi Fire: it only works sitting on a Solo Stove fire pit. A second Ninja listing titled OO100: 10 ratings, sold by an individual reseller; SharkNinja lists OO100 only as the series name for the Woodfire.
What a pizza night costs in fuel
Electric: well under 50 cents. The Artisan’s listing rates it at 1,760 W. Run flat out for an hour, that is 1.76 kWh — about 32 cents at EIA’s June 2026 U.S. residential average of 18.34 cents per kWh — and the element cycles once it is hot, so a real session costs less. The Woodfire adds its pellets, which Ninja puts at half a cup a session.
Wood: a few dollars, and a job. Tom’s Guide cooked five pizzas in the Karu 2 on “2-3 handfuls of lumpwood charcoal and 5-6 small logs — not much.” Kiln-dried hardwood, not pellets, and never treated or painted wood.
Gas: a burner first. Ooni sells the gas burner separately — $120 for the 12 in ovens, $140 for the 16 in — and after that it runs off a standard propane tank.
Where these fit on the site
The Karu line sits on price beside our gas ovens — the Karu 2 near the Lightweight Roccbox and Koda 2, the Karu 2 Pro near the Middleweight Koda 2 Pro and Arc — but a Karu only fights a gas oven after you buy its burner, so we keep them apart. If you already know you want gas, start with the gas division ladder; if you want the flagship end, see the Heavyweight showdown.
FAQ
Is the Ooni Karu or the Ninja Woodfire better?
They are different ovens for different people. The Ooni Karu burns real wood or charcoal and tested stone temperatures above 750°F; the Ninja Woodfire is an electric oven that tops out at 700°F and adds wood-pellet smoke for flavor. For pizza, the Ooni Karu 2 is the better oven — 4.5★ from 215 owners and a top pick at Tom's Guide. If you do not want to tend a fire, the better Ninja for pizza is the Artisan, not the Woodfire.
Is the Ninja Woodfire pizza oven really wood-fired?
No. It heats with electricity. The wood pellets go in a small box for smoke flavor, and Ninja's own wording is that they are for flavor, not fuel. Reviewed.com, which tested it, noticed no intense smoke flavor on quick-cooking food like pizza and found real smoke on a chicken cooked for 55 minutes.
Does the Ooni Karu come with a gas burner?
No. The Karu 12, Karu 2 and Karu 2 Pro ship ready for wood and charcoal only; gas needs Ooni's burner, sold separately. It is the most common complaint in their critical reviews — owners bought a multi-fuel oven and found the gas part was extra.
What is the best electric outdoor pizza oven?
The Ninja Artisan, at 4.7★ from 509 owners and sold by Amazon itself. Tom's Guide measured 18 to 20 minutes to 700°F and called cooking basically hands-off. The Ooni Volt 2 gets hotter, to 850°F, but Ooni rates it for indoor use only, and six of the ten newest critical reviews on its listing report a cracked pizza stone.
Is the BIG HORN pizza oven any good?
It is Amazon's best-selling outdoor oven and owners who learn it like it, at 4.4★ from 2,652. We still skip it: no credentialed outlet has tested it, owners report pellets that are hard to light and heat that will not hold, and BIG HORN's own site says its 24-month warranty is only valid on bighornoutdoor.com purchases — not the Amazon listing most people buy.
Does a wood-fired oven make pizza taste smoky?
Less than you would think. A Neapolitan pizza bakes in 60 to 90 seconds, and one Karu 12 owner who switched from charcoal to gas wrote that they could not tell the difference in taste. What wood gives you is heat — the Karu line tested at stone temperatures of 750°F and more, about 50°F or more above the 700°F ceiling of either Ninja.
