Solo Stove Pi vs Ooni Karu 12G — Wood-Fired Portable Showdown
The Solo Stove Pi and Ooni Karu 2 are the two flagship wood-capable portable pizza ovens at the sub-$550 price point. Both run wood. Both run gas (with the right accessory). Both target the patio-and-tailgate buyer who wants full Neapolitan capability without the weight or cost of a Roccbox or Karu 2 Pro. The differences hide in fuel-handling design, build aesthetic, and a $75 price gap.
Spec-by-spec head-to-head below.

Where the Karu 2 wins
The Ooni Karu 2 is the more capable oven on paper at every dimension that matters for Neapolitan cooking. 950°F max temp clears the Neapolitan threshold cleanly; the Solo Stove Pi caps at 850°F, putting it in "Neapolitan-style" territory rather than full VPN compliance. That 100°F gap shows up in the cornicione leoparding pattern — the Karu's cornicione develops the dark, blistered spots that define the style; the Pi's stays more uniformly browned.
Fuel flexibility is the second Karu advantage. The Karu 2 ships with native support for gas, wood, and charcoal — buy one oven, run all three. The Solo Stove Pi ships wood-only by default; the gas burner is a separate accessory. That accessory adds $200+ to the Pi's $525 base price, pushing the all-in cost above the Karu's $449 sticker.
Weight favours the Karu too — 33.6 lbs vs Pi's 30.5 lbs. Both are nominally portable; the 3-lb gap matters most on extended carries (camping, trail-tailgating).
Where the Pi wins
The Solo Stove Pi's strongest argument is aesthetic and build presence. The 304 stainless-steel demi-dome construction is genuinely beautiful in a way the Karu's more utilitarian sheet-metal-and-vent design isn't. For buyers who want the oven to look like a centerpiece on the patio rather than a tool tucked in the corner, the Pi has a real edge.
The Pi's circular geometry also gives it more even radiant heat distribution at lower flame settings — a small but real advantage for cooks who often run wood-only at sub-Neapolitan temperatures (NY-style at 700°F, for example). The Karu's rectangular chamber concentrates heat at the rear flame more aggressively.
Solo Stove's accessory ecosystem also matters. The Pi pairs with the broader Solo Stove fire-pit family — Bonfire, Yukon, Ranger — which means a buyer already in the Solo Stove ecosystem benefits from accessory cross-compatibility.
Where they're roughly tied
- Build durability — both 304-grade stainless steel; both designed for outdoor exposure with proper covering
- Cooking experience at NY-style and Detroit temperatures (700°F and below); the temperature gap doesn't matter at these styles
- Stone quality — both use cordierite at 13"
- Outdoor-only — neither is indoor-rated; both require open-air operation
Decision rules
- If you cook Neapolitan more than 50% of the time — Karu 2. The 100°F max-temp advantage matters.
- If you cook NY-style + Detroit + occasional Neapolitan — Either works. Pick on aesthetic.
- If you'll buy the gas accessory for the Pi anyway — Karu 2. The all-in cost favours it.
- If you're already in the Solo Stove ecosystem — Pi. Cross-compatibility with fire-pit accessories.
- If you want the most beautiful oven on the patio — Pi. Genuine aesthetic edge.
- If you want the most capable oven on the patio — Karu 2. Spec sheet leads at every dimension.
The verdict
For most buyers cross-shopping these two, the Ooni Karu 2 is the rational pick — better max temp, native multi-fuel, lighter, cheaper. The Solo Stove Pi wins on aesthetic and ecosystem cross-compatibility, which are real but secondary considerations for a cooking tool. If aesthetics tip the decision for you, the Pi is a defensible choice; if you want the best-cooking oven at this price point, the Karu 2 is the answer.
FAQ
Does the Solo Stove Pi gas accessory bring it to 950°F?
The accessory adds the gas-burner option but doesn't raise the oven's thermal ceiling. The Pi caps at 850°F regardless of fuel type — that's a chamber-design constraint, not a fuel-availability one.
Can I run charcoal on the Solo Stove Pi?
The Pi is officially wood-fueled (or gas with accessory). Charcoal isn't a documented fuel option — running it would be off-spec and may damage the chamber. The Karu 2 supports charcoal natively.
Which has faster recovery between pies?
Both are in the 1-2 minute recovery range with their respective fuel types. Wood-mode adds ~1 minute over gas-mode for both. Hosting throughput differences between the two are marginal.
Can either run during winter?
Yes for both — they're outdoor-rated stainless steel. Cold air slows preheat by 2-5 minutes vs summer. Always store the cordierite stone indoors after each cook to prevent moisture absorption.
