The Skavelo SDK is a small, framework-agnostic TypeScript package. It renders inside a Shadow DOM, does nothing during server rendering, and needs no API key: the agent ID and your [allowed sites](/docs/installing/allowed-sites) are enough. Install it from npm as [`@skavelo/sdk`](https://www.npmjs.com/package/@skavelo/sdk), or use the script tag.

For an overview of what developers can do with Skavelo, see [skavelo.com/developers](https://skavelo.com/developers).
