About Stremio

Stremio Web is the browser-based front end of Stremio, a media center that brings video entertainment together in one place. Content is discovered through catalogs supplied by addons, and a user's library and Continue Watching list follow their Stremio account across devices.

The interface covers casting to Chromecast, subtitles from addons or local files with adjustable styling, a keyboard-driven player, and community translations into more than 50 languages. It can be installed as a standalone progressive web app. Behind the scenes, the UI is a React application, while state and addon logic live in stremio-core, a Rust engine compiled to WebAssembly and run in a Web Worker.

The code is released under the GPL-2.0 license. To work on it you need a recent Node.js and pnpm, and the repository documents a development server, production build, tests and linting, along with a Docker option. A hosted copy of the web app is available at web.stremio.com.
