Plane is a container orchestrator for ambitious browser-based applications. Plane implements an architecture we call session backends.
tl;dr: Plane lets you spin up instances of any HTTP-speaking container via an API. Plane assigns a unique subdomain to each instance, through which it proxies HTTPS/WebSocket connections. When all inbound connections to a container are dropped, Plane shuts it down. Plane is MIT-licensed and written in Rust.
