If you are shopping for an outdoor pizza oven in the UK, two names dominate the conversation: Ooni and Ninja. Ooni built the category and still sets the benchmark for pizza purists. Ninja arrived later with the Woodfire and did something clever — it turned the pizza oven into a whole outdoor cooker. They look like direct rivals, but they are actually built for two different types of buyer, and picking the wrong one is the most common mistake I see people make. This guide breaks down exactly who each one is for.
The short answer
Buy the Ninja Woodfire Outdoor Oven if you want one appliance that makes decent pizza and roasts, bakes, smokes and grills — a versatile all-rounder for a family that will use it for far more than pizza. Buy an Ooni if pizza is the point, you want the best possible crust, and you are happy to run a dedicated oven that does one job superbly. Most families are better served by the Ninja; most pizza obsessives will be happier with the Ooni.
What each one actually is
Ninja Woodfire — the outdoor multi-cooker
The Ninja Woodfire at around £350 is electric, with a small pellet tray that adds a genuine hint of woodfired smoke. Its headline trick is versatility: it hits pizza temperatures but also runs as an air fryer, a roaster, a baker and a cold-and-hot smoker. It plugs into a standard 13A socket, so there is no gas bottle to manage, and it works on a covered patio or balcony where an open-flame oven would not be safe. The trade-off is that its top temperature (around 370–400°C) is lower than a dedicated gas oven, so pizzas take a little longer and the leopard-spotted char is harder to achieve.
Ooni — the dedicated pizza specialist
Ooni makes a range, but the Koda 16 (gas, £499) is the one most directly compared to the Ninja. It reaches 500°C+, which cooks a proper 60-second Neapolitan pizza with the puffed, charred cornicione that defines the style. It does nothing except pizza — no roasting, no smoking — but it does pizza better than anything else at the price. Ooni also offers the electric Volt 2 for indoor/outdoor use and the multi-fuel Karu 12G if you want real wood-fire flavour.

Pizza quality: the honest verdict
There is no getting around the physics here. Authentic Neapolitan pizza is defined by a very hot, very fast bake — the Associazione Verace Pizza Napoletana specifies a floor temperature around 430°C and a bake of 60–90 seconds. The Ooni Koda 16 hits that comfortably. The Ninja, running cooler, gives you a very good pizza in four to six minutes — crisp base, melted top, a light smokiness from the pellets — but it is a slightly different, more "home-baked" result than the blistered, airy crust an Ooni produces.
If you have eaten a lot of proper pizza and you care about that specific texture, you will notice the difference and the Ooni is worth the extra £150. If you just want a genuinely tasty homemade pizza that beats anything from a supermarket or a chain, the Ninja delivers that easily, and most people at a garden gathering could not tell you which oven it came out of.
Versatility: where the Ninja pulls ahead
This is the Ninja's trump card and it is a big one. For the same money as a pizza-only Ooni, you get an appliance that will also cook a Sunday roast chicken, bake bread, smoke a brisket, and air-fry a tray of chips — outdoors, without heating up the kitchen in summer. If you are the kind of household that will use it once a week for all sorts of cooking, the Ninja's cost-per-use is far lower because it replaces several appliances rather than sitting idle between pizza nights. If you fancy building the Ninja into a wider setup, our outdoor kitchen cost guide covers how the numbers stack up.
Running costs and practicality
The Ninja runs on electricity — a pizza session costs pennies and there is no gas bottle to buy, store or run out of mid-cook. The Ooni Koda 16 needs a propane bottle; the gas itself is cheap per pizza, but you have to manage the bottle and store it safely. For flats, balconies and covered patios, the electric Ninja is often the only one of the two you can legally and safely use, since open-flame gas ovens need proper outdoor ventilation and clearance.
On heat-up, both are quick: the Ninja is ready in around 10–15 minutes, the Koda 16 in 15–20. Neither is a slow burner like a wood-fired dome. If you are weighing fuel types more broadly, our gas vs wood-fired guide goes deeper on the flavour-versus-convenience trade-off.
Which should you buy?
Choose the Ninja Woodfire if…
- You want one appliance for pizza and roasting, baking, grilling and smoking
- You do not want to deal with a gas bottle, or you are on a balcony or covered patio
- You want the lower price and the lower cost-per-use of a do-everything cooker
- "Very good" pizza is plenty — you are not chasing competition-grade Neapolitan crust
Choose an Ooni if…
- Pizza is the whole point and you want the best crust money can buy at this price
- You want to cook 16" pizzas or run 500°C+ for a true 60-second bake
- You already have a barbecue or oven for everything else
- You value doing one thing brilliantly over doing many things well
The verdict
These two ovens are not really competitors — they are answers to different questions. The Ninja Woodfire is the smarter buy for a family that wants versatile outdoor cooking and treats great pizza as one feature among many. The Ooni is the better buy for a pizza enthusiast who wants the definitive result and does not need the oven to do anything else. Decide which of those two people you are, and the choice makes itself.
