The NiD.29 was an equal-span biplane with ailerons on both upper and lower wings. It had a fixed tailskid landing gear, a nose-mounted engine and a single open cockpit for the pilot. The prototype NiD 29 first flew on the 21 August 1918 powered by a Hispano-Suiza 8Fb engine piston engine, it performed well in test but could not achieve the required ceiling. The second prototype was modified with an increased wingspan and on achieving the required ceiling it was ordered into production in 1920, becoming the fastest service fighter in the world at that time. Production aircraft did not have ailerons on the upper wing and the lower wing ailerons were increased in size.

The first deliveries were made in 1922 to the French Air Force and the type was popular although it did have a tendency to enter a flat spin. The French military bought 250 aircraft which were built by Nieuport and seven other companies. The Ni-D 29 was to become an important fighter in the 1920s with purchases of 30 by Spain (including 10 Spanish licence built aircraft), 108 by Belgium (87 licensed built by SABCA). The Italian Regia Aeronuatica bought 175 aircraft including 95 built by Macchi as the Macchi-Nieuport 29 and 80 built by Caproni. Sweden bought nine aircraft and designated them J 2. The Japanese company Nakajima bought a pattern aircraft and built 608 for the Imperial Japanese Army as the Ko-4.

Racing versions of the aircraft were developed and they gained eight world speed records and won the 1920 Gordon Bennett Trophy and the 1922 Coupe Deutsche de la Meurthe races.
