# Log-in tool

Improve your user experience by incorporating the Gravity SDK into your game. We understand that a fragmented ecosystem with separate login forms poses a major hurdle for user onboarding, and we aim to overcome it.

By integrating Gravity SDK services, your game can offer a seamless "click and play" experience for new players. Our Auth Services provide user authentication and seamlessly integrate with Gravity features, offering simple and easy-to-implement add-ons for your game.

This tool currently supports Unity and Unreal Engine 4 developments, but we are actively working to expand compatibility with additional development engines.

It's also compatible with every Metamask & WalletConnect supported chain.
