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.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/rainway: open an issue to ask a question, or submit a pull request to add artifacts.
