iroh

Iroh is an open-source toolkit designed for building distributed applications, offering seamless syncing across devices without requiring a central server. It establishes direct connections, effectively handling network address translation (NAT) and ensuring high connection rates. This allows developers to create dynamic shared environments with instant read and write operations, simplifying the development process. Iroh supports data transfer of any magnitude, maintaining peak performance even when individual device capacities are exceeded.

The toolkit facilitates zero-cost tooling by enabling direct connections without incurring bills. It also allows users to build self-sustaining networks, making it possible to transfer data between devices effortlessly. For instance, users can start a movie on their computer and continue watching it on their phone, carrying the data along.

Iroh supports multiple programming languages, integrating nodes directly into projects without the need for external APIs. Developers can connect to a global network of Iroh nodes for seamless cloud backing, ensuring data availability at all times. The toolkit includes projects like "dumb pipe" for direct device connections and "sendme" for free file transfers without an account.

For quick setup, developers can install the CLI and follow the quickstart guide provided on the product's website.
