# Smelter

> Smelter is a low-latency, real-time video compositing toolkit built by Software Mansion. Combine multimedia from different sources into a single video or live stream, enrich it with text, custom shaders, and embedded websites — using React components (TypeScript SDK) or directly via an HTTP API. Common uses: live streaming, broadcasting, and video conferencing.

## For AI coding assistants

If you are building with the Smelter **TypeScript SDK** (`@swmansion/smelter` and its runtime packages `@swmansion/smelter-node`, `@swmansion/smelter-web-client`, `@swmansion/smelter-web-wasm`), install the official **`smelter-ts-docs`** Agent Skill instead of scraping these pages. It is the complete, versioned API reference — components, inputs, outputs, hooks, encoders, shaders, and side-channel processing — so you don't have to guess prop names, defaults, or runtime availability.
