COBI and LEGO barely compete. COBI builds the tanks, warships and military aircraft LEGO has chosen never to make, while LEGO owns licensed fiction, Technic and the resale market. This guide covers what each brand makes, whether the bricks fit together, stickers versus printing, price per piece, and which to buy for ships, jets, Jeeps and classic cars.
COBI and LEGO are not really rivals. COBI builds the things LEGO has decided never to make: Tiger tanks, battleships, fighter jets and the soldiers who crewed them. LEGO builds almost everything else, from Star Wars to Technic supercars, and has by far the larger resale market. The only real choice comes where they overlap, on the Titanic, civil aircraft, Jeeps and classic cars, and this guide walks through each one.
Who COBI is
COBI is a Polish company founded in Warsaw in April 1987. It started with puzzles and board games, began making plastic construction blocks in 1992 and has built its sets since 1997 in its own factory in Mielec, in south-eastern Poland, where it designs and manufactures every model. LEGO took COBI to court in Poland, and the case was dismissed in 2001, so COBI has spent more than two decades selling its own designs on the same brick standard.
Its range follows history rather than fiction: collections for World War I, World War II, the Korean and Vietnam wars, the Cold War and present-day armed forces, plus civilian cars and aircraft. Its licenses are with real manufacturers and studios, among them Boeing, Lockheed Martin, Northrop Grumman, Sikorsky, Dassault Aviation, Jeep, Volkswagen, Audi, Fiat, Maserati, Škoda, Toyota and Paramount's Top Gun.
Why LEGO does not make what COBI makes
LEGO has a long-standing policy of avoiding realistic modern weaponry. Its stated aim is to avoid realistic weapons and military equipment that children may recognize from hot spots around the world and to refrain from showing violent or frightening situations. LEGO keeps weapons inside fantasy settings: castles, pirates, Star Wars. That one decision is why COBI exists as a serious brand. If you want a Tiger tank, a Super Hornet or the Bismarck in bricks, there is no official LEGO alternative to weigh it against.
Do COBI bricks work with LEGO?
Yes, for the bricks. COBI says its blocks are fully compatible with other leading brands, and the studs and spacing match, so a COBI wall will sit on a LEGO baseplate. Builder reviews describe COBI's clutch as firm, if anything a little tighter than LEGO's.
The figures are the bigger difference. COBI figures have more realistic proportions, shorter legs and period uniforms and equipment, which suits a diorama and can look out of place beside a classic LEGO minifigure. If you plan to mix the two on one shelf, keep each brand's figures with its own models.
The finish differs too. COBI says more than 90 percent of its sets use printed elements instead of stickers, and its Bismarck and Graf Zeppelin ships list no stickers at all. LEGO uses a mix of printed pieces and sticker sheets.
Where they overlap: the Titanic
This is the cleanest head-to-head. LEGO's Titanic is one of its largest sets, a display piece over a meter long that splits into three sections. COBI's RMS Titanic is built at 1:450 scale, a fraction of the size, with a more detailed Executive Edition at the same scale. Choose LEGO for a centrepiece, COBI for a Titanic that fits an ordinary shelf.

Where they overlap: aircraft
LEGO builds civil and space aircraft; COBI builds mostly military ones, many under license from their manufacturers. If the aircraft you want carries weapons, COBI is the only option. If it carried passengers or astronauts, LEGO's display models are the natural choice.

The Concorde is expected to leave LEGO's shelves at the end of 2026, so it is the one to decide on first. On the COBI side, its Top Gun license covers the F/A-18E Super Hornet flown in the film.

Where they overlap: Jeeps and classic cars
Both brands hold car licenses, and here the choice is about era. COBI's Jeep license covers the wartime Willys MB, which it builds at several scales including a large 1:12 model. LEGO's Jeeps are modern Wranglers, such as the Technic Wrangler Rubicon.

For classic cars, LEGO's display models include the Ford Model T and the Porsche 911, and COBI's licensed cars cover a different list of makes, including Fiat, Škoda and Maserati.

Porsche 911 Turbo and 911 Targa: one build, two versions of the classic 911 to choose between.
Only COBI: tanks, warships and military vehicles
This is COBI's home ground and LEGO has no answer by design. The Historical Collection covers WWII tanks and vehicles, and the Executive Edition warships are the brand's showpieces: the Battleship Bismarck and the Battleship Yamato are both built at 1:300 scale and run close to three feet long.

Price, resale and where to buy
Price per piece usually favors COBI, but the gap is modest. A June 2025 sample of several sets per brand by Geek Native put COBI at about 7p a brick against about 9p for LEGO. Prices vary by set and retailer, so check the piece count on the box against the price.
Resale is where LEGO pulls away. Retired LEGO sets trade on a large, well tracked secondary market, and some sell for more than they cost new. COBI has nothing comparable, so treat a COBI set as something to build and display, not to hold. COBI sells through its own stores, including one for the US, and through Amazon; LEGO is sold everywhere.
Which should you buy?
- A WWII tank, warship or military jet: COBI. LEGO does not make one.
- The Titanic as a centrepiece: LEGO, if you have the room. COBI if you want it on a normal shelf.
- Civil or space aircraft: LEGO's display models.
- A wartime Jeep: COBI's Willys MB. A modern one with working functions: LEGO Technic.
- Something that might hold its value: LEGO.
- No stickers: COBI, in most sets.
