Rainway

Rainway is a developer platform for interactive application streaming, letting you embed and run native apps anywhere in a few lines of code. Its Stream SDK is built on WebRTC and ships runtimes for the Web, React, Node.js (native), .NET and C++, handling secure peer connections, low-latency media streaming, network adaptation and input. A small RESTful Hub API exposes the active peers connected to the Rainway Network, authenticated with an API key pair, for building multi-peer architectures. Rainway originated as a consumer game-streaming app (2017; consumer app wound down in 2022) and pivoted to the Stream SDK; the docs, Hub, and published packages remain live.

Rainway publishes 1 API on the APIs.io network: Peers API. Tagged areas include Company, Streaming, Application Streaming, WebRTC, and Game Streaming.

Rainway’s developer surface includes documentation, getting-started guide, API reference, signup flow, authentication, and 17 more developer resources.
