Updated August 2026: TechGearLab’s measured average and peak temperatures are shown side by side for each oven — peaks run near 1,100°F on three of the four. Ooni’s Koda 2 is sold out in every colour on Ooni’s own store. The Solo Stove Pi Prime is $359.99 on Solo Stove’s own site. No cost-per-pizza-night figure appears here: three of these four makers publish no gas consumption rate to compute one from.
Weighing Ooni vs Gozney vs Solo Stove, the Solo Stove Pi Prime is the pizza oven to buy. It scores 85.5 out of 100 on the five weighted axes below, eight points clear of anything else here. That is because it pairs strong heat with the lowest price and the lightest body at 30 pounds. The Gozney Arc runs hotter than any other outdoor pizza oven on this page and finishes last on the tally at 75.8, which is the whole argument of this comparison. Heat is a quarter of the score. It is not the score.
Cooking outside in Florida heat, I’d rather deal with something light I can move and store easily. A few extra degrees of peak heat don’t matter much if the oven that hits it costs more and weighs more.
- The pick: Solo Stove Pi Prime, $359.99. Cheapest, lightest, 911°F average. Twelve-inch stone is the catch.
- If you want 14-inch pies: Gozney Arc, $799.99. The hottest oven measured, and 47.5 pounds of it.
- If you want fire: Ooni Karu 2, $449. Wood, charcoal, or a gas burner Ooni sells separately and does not price on the product page.
- The one you cannot have: Ooni Koda 2, $499, sold out in all three colours on ooni.com.
Ooni vs Gozney vs Solo Stove: which pizza oven wins the tally?
After hurricane seasons of hauling gear inside before a storm, the Solo Stove Pi Prime is the one I’d point a friend to, because 30 pounds is easy to carry alone. The Solo Stove Pi Prime wins this five-axis tally with a weighted score of 85.5 out of 100, eight points ahead of anything else in this comparison. It pairs the third-hottest average temperature in the group with the lowest price and lightest body of the four ovens.
Every axis below is scored 0 to 10, multiplied by its weight, and summed. Price is scored by dividing the cheapest oven’s price by each oven’s price and multiplying by ten. So the $359.99 Pi Prime scores 10.0 and the $799.99 Arc scores 4.5 ($359.99 ÷ $799.99 × 10). Temperature is scaled the same way against the hottest average. Disagree with a weight? Change it and re-run the row. That is what the numbers are for.
| Axis (weight) | Gozney Arc | Solo Stove Pi Prime | Ooni Koda 2 | Ooni Karu 2 |
|---|---|---|---|---|
| Measured average temperature (25%) | 10.0 | 9.4 | 9.6 | 8.0 |
| Pizza size (20%) | 10.0 | 6.5 | 10.0 | 6.5 |
| Price at the maker (25%) | 4.5 | 10.0 | 7.2 | 8.0 |
| Availability and warranty terms (15%) | 8.0 | 8.0 | 3.0 | 6.5 |
| Weight and fuel flexibility (15%) | 5.0 | 8.0 | 7.0 | 9.5 |
| Weighted total | 75.8 | 85.5 | 77.0 | 77.0 |
Why Do Temperature and Price Each Carry 25 Percent?
Temperature and price each carry 25 percent because they are the two things that actually separate these machines. Everything here clears the 750°F a decent pizza needs, and the price spread is more than two to one. Pizza size takes 20 percent because a 12-inch stone is a hard ceiling, not a preference, if you are feeding four people in one bake. Availability and warranty take 15 percent, which is more than most comparisons give them and is the reason the Koda 2 does not win this page. Weight and fuel flexibility take the last 15 percent.
The Arc wins two axes outright and still finishes last. It costs $440 more than the Pi Prime and gives back two inches of stone and a slightly hotter fire. That is a real thing to want. It is not a 2.2x thing to want.
Do Ooni, Gozney, and Solo Stove Ovens Hit Their Advertised Heat?
Gozney, Ooni and Solo Stove all advertise the same ceiling: 950°F. All four ovens on this page carry it. When one company and then a second and then a third arrive at the identical round number, that number is a specification of the marketing, not of the oven.
TechGearLab is the only outlet I could find that publishes discrete measured air and stone temperatures for these specific models, in its pizza oven rankings last updated November 2025. Its figures do not line up with the claim in either direction, and the gap runs both ways.
| Oven | Maker’s stated max | Measured average air | Measured peak air | Measured average stone |
|---|---|---|---|---|
| Gozney Arc | 950°F | 969°F | 1,105°F | 871°F |
| Ooni Koda 2 | 950°F | 935°F | 1,102°F | 848°F |
| Solo Stove Pi Prime | “in excess of 950°F” | 911°F | 1,100°F | 841°F |
| Ooni Karu 2 | 950°F | 776°F | not published | 825°F |
Three readings out of that table. The peaks beat the claim by 150 degrees or more, so the makers are underselling the top of the range. The averages sit at or below the claim, which is the number that matters, because you cook at the average and not at the spike. And the Karu 2 is the only oven here whose stone runs hotter than its air, 825°F against 776°F. That is not a transcription error. It is what a wood fire under a stone does.
How Reliable Is the Ooni, Gozney, and Solo Stove Heat Data?
These are comparative in-house measurements under an undisclosed protocol, from a single outlet, and that is one honest limit worth flagging. TechGearLab describes using an infrared thermometer for the stone readings. It does not publish how the air averages were taken, over what interval, or at what burner setting. Anyone telling you a consensus of laboratories has ranked these ovens is counting to one.
The full rankings and per-model reviews are at TechGearLab’s pizza oven testing. Tom’s Guide reviewed the Arc separately in September 2024 and reported only a loose “800 to 900 degrees F” band with no methodology and no air-versus-stone split. That is why it is not in the table.
What Do Ooni, Gozney, and Solo Stove Ovens Cost at the Maker?
The Ooni Koda 2 lists at $499 but is sold out in every colour on Ooni’s own store. The Solo Stove Pi Prime remains the cheapest of the four at $359.99. Two of them have moved since this page was first written, in opposite directions, and one oven cannot be bought from the company that makes it.
| Oven | Price at the maker | Stock | Max pizza | Weight | Warranty |
|---|---|---|---|---|---|
| Gozney Arc | $799.99 | Available | 14" | 47.5 lb | 1 year, 5 with registration |
| Solo Stove Pi Prime | $359.99 (from $399.99) | Available | 12" | 30 lb | Lifetime claimed; exclusions not published |
| Ooni Koda 2 | $499.00 | Sold out, all three colours | 14" | 35.3 lb | 1 year, 5 with registration |
| Ooni Karu 2 | $449.00 | Available | 12" | 33.7 lb | 1 year, 5 with registration |
Prices are approximate, current as of publication, and change frequently — confirm the latest price with the retailer before buying.
Read the warranty column twice. Ooni’s five years is conditional on registering within 60 days and on having bought the oven from Ooni directly. Buy a Karu 2 at Costco and you have a one-year warranty, whatever the marketing implies. Solo Stove says lifetime, but its warranty terms page returned a 404 when I went looking for the exclusions. So I cannot tell you what that lifetime excludes, and neither, from that page, can you.
What I could not price at all: gas. Gozney publishes a consumption rate for the Arc, 4.5 kW or 330 grams an hour, in its help centre. Ooni publishes no consumption figure for the Koda 2 or either Karu, and Solo Stove publishes none for the Pi Prime. So a cost-per-pizza fuel number for three of these four ovens would be a number I made up, and it is not in this comparison.
Gozney Arc: the highest ceiling, the lowest total
The Arc took TechGearLab’s Editors’ Choice and posted the highest average of the eight ovens in that test, 969°F, with a peak of 1,105°F. Fourteen-inch stone, 20 mm thick and removable. It is the only oven here I would call furniture rather than equipment.
It is also $799.99, up from the $699.99 Tom’s Guide recorded in September 2024. Prices in this category are moving up, not down, which is worth knowing if you have been waiting for a sale. At 47.5 pounds it lives where you put it.
Skip this if you have not yet established that you will fire an outdoor oven more than a handful of times a year. Eight hundred dollars is an expensive way to discover you are a four-pizzas-a-summer household.
Solo Stove Pi Prime: lightest, cheapest, and the winner here
The Solo Stove Pi Prime is the cheapest and lightest oven in this comparison at $359.99 and 30 pounds, with a measured average temperature of 911°F, the third-hottest of the four ovens tested here.
911°F average, 1,100°F peak, 30 pounds, $359.99. It gives up 58 degrees of average heat to the Arc and takes $440 back. TechGearLab gave it the Best Buy award. Its own optimal cooking range for the oven, 750°F to 850°F, sits below the average the thing actually holds.
The stone is 12 inches. That is one pizza for one adult, and it is the reason this oven does not win every axis. Gas only, no wood path. Solo Stove sells a separate wood-burning Pi Prime, which is a different product rather than a conversion kit.
Skip this if you want one shared 14-inch pie per bake rather than a queue of personal ones. Cooking in rounds is fine for two people and tiresome for five.
Ooni Koda 2: fourteen inches, no award, no stock
The Koda 2 posts the second-highest average in the field at 935°F and peaks at 1,102°F, on a 14-inch stone, for $499. On the numbers it is the cheapest route to a large pie. TechGearLab still ranked it sixth of eight and gave it nothing. Its reviewer’s complaint was the control: a dial with no temperature markings, no recommended settings, no indication of where the useful zone is.
Then there is the part that decides its score here. Every colourway on Ooni’s own product page reads Sold Out with a notify-me button. It is not discontinued, and it still sits at $499 in Ooni’s pizza oven collection alongside the Koda 2 Pro and Koda 2 Max. You simply cannot buy it from Ooni today. Ignore the scarcity counter on that page, which reads “only 2,428 left” on an item every variant of which is out of stock.
Skip this if you need the oven this month. Watch the stock page instead of paying a reseller a premium for the same box.
Ooni Karu 2: wood, charcoal, or a burner Ooni won’t price
The Ooni Karu 2 is the only oven on this page that burns wood, and it took TechGearLab's Top Pick for multi-fuel. It is 33.7 pounds and $449, and its 776°F average air temperature is the lowest here by 135 degrees while its stone runs the second-warmest of the four.
The gas burner is sold separately and Ooni does not publish a standalone price for it on the product page. I can infer roughly $120 from the gap between the bundle and the bare oven, but inferring a price from a bundle delta is not the same as knowing one. So treat the Karu 2 as a $449 oven that costs more than $449 the moment you want it to behave like the other three.
Skip this if you want to cook on a weeknight. Wood wants tending between pizzas, and the 12-inch stone means you will be tending it more than once.
Have Ooni, Gozney, or Solo Stove ovens been recalled?
I searched CPSC recall notices for Ooni, Gozney and Solo Stove and found nothing for any of them. That is “no recall found,” not “no recall exists”. The CPSC search endpoint refuses automated queries, so this was targeted searching rather than an exhaustive sweep of the database.
What did turn up is adjacent and recent. On 9 July 2026, Conair recalled about 12,660 Cuisinart Propel+ four-burner grills, model CGG-6331. The tempered glass window in the grill’s pizza oven can shatter during use. Thirty-seven reports of shattered glass, one fire, no injuries reported, $500 refund.
No oven on this page has a glass door. Ooni’s Karu 2 Pro, which is the next model up from the Karu 2, does have a glass door, in borosilicate rather than tempered glass. It has no recall and no reported failure pattern. If you are shopping one rung above this comparison, that is the honest answer rather than silence.
Ooni Koda 2 vs Ooni Karu 2: which should you buy?
The Ooni Koda 2 and the Ooni Karu 2 finish level at 77.0. Not close. Level. They get there by opposite routes. The Koda 2 buys heat and stone size and loses on stock, while the Karu 2 buys fuel flexibility and portability and loses on temperature and pie size.
My money goes to the Karu 2, on one condition: that you actually intend to burn wood in it. Wood is the only thing on this page a $359.99 Pi Prime cannot do. It is the only reason to accept a 12-inch stone and the lowest average temperature of the four. Budget above the $449, because the gas burner is extra and unpriced.
If you want gas, I would not buy either of these two. Buy the Pi Prime the tally already picked.
Is the Gozney Arc Lite worth considering instead?
Gozney now sells the Arc Lite, a 12-inch gas oven, at $349.99 down from $399.99. It undercuts the Pi Prime by ten dollars, from the company that builds the hottest oven in the field.
It is not in the tally because nobody has published measured temperatures for it. Scoring an oven on a maker’s own claim, after spending this page explaining that the claim is a round marketing number, would be dishonest. So: a live candidate, no evidence yet, and you should know it exists before you spend $359.99 on the winner. Gozney’s Tread at $499.99 and the Roccbox at $399.99, now well below the $500 TechGearLab still lists, are in the same position.
What Should You Check Before an Ooni, Gozney, or Solo Stove Buy?
Prices in this category move, and the cheapest 14-inch oven in the group went out of stock at its own maker. Open the maker’s page, confirm the oven is buyable and confirm the number, then come back and re-run the tally with today’s figures. The weights are yours to change.
If the patio project runs past pizza, the pellet grill comparison covers the smoke end of it, dessert is handled in the cost-per-quart ice cream maker comparison, and the indoor equivalent of this argument is in the air fryer comparison. Everything else is in Kitchen & Cooking.
