# Overview

Bridgefy creates mesh networks in which devices connect directly to each other in a decentralized manner. This allows users to communicate with nearby devices within a certain range, forming a network without the need for a centralized server or Internet access.

The Bridgefy SDK provides a set of tools and APIs that developers can use to incorporate offline messaging, data transfer, and real-time communication features into their applications. It allows users to send data directly to other nearby devices using Bluetooth Low Energy.
