Stremio — Open-Source Streaming Media Center with Add-On Ecosystem

Introduction

Stremio is a media center application that organizes and streams video content from multiple sources. Its add-on architecture allows community developers to build content providers without modifying the core application.

What Stremio Does

• Aggregates movies, series, and live channels in a unified interface
• Manages a personal library with watch progress tracking across devices
• Supports community add-ons for content discovery and streaming
• Provides subtitle search and integration from OpenSubtitles
• Streams via HTTP, BitTorrent, and other protocols through add-ons

Architecture Overview

Stremio uses a client-server model. The web frontend is built with React and communicates with a local streaming server that handles media transport. Add-ons are standalone HTTP services conforming to the Stremio Add-On SDK protocol, returning JSON manifests and content catalogs.

Self-Hosting & Configuration

• Deploy stremio-web behind any static file server or CDN
• The streaming server runs locally or on a dedicated host
• Add-ons can be self-hosted as Node.js HTTP microservices
• User accounts sync libraries across devices via Stremio cloud
• Configuration is managed through the settings UI or environment variables

Key Features

• Cross-platform: desktop (Electron), Android, iOS, Samsung TV, and web
• Add-on SDK lets anyone build and publish content sources
• Chromecast and DLNA casting support built in
• Calendar view for tracking upcoming episode releases
• Local file playback alongside streamed content
