Uniswap is a decentralized exchange (DEX) trading platform that uses automated market makers (AMMs) and smart contracts to handle trades without the need for a central middleman.
Coinbase and Binance, on the other hand, are centralized trading platforms run by central authorities or any company. These platforms connect the buyer and seller.
Because of the decentralized feature of Uniswap, users have the authority of their funds, unlike centralized exchanges that hold user assets.
Lower fees are usually associated with trading on Uniswap, mainly gas fees (blockchain transaction costs), which vary according to network activity.
