# Introduction to TronGrid
TronGrid provides an API interface into the TRON Network.
Similar to <a href="https://infura.io/" target="_blank">Infura</a> on the Ethereum platform, Tron Grid provides Tron clients running in the cloud, so you don't have to run one yourself to work with Tron. Tron Grid allows developers to access important tools to develop decentralized applications on the Tron protocol.
