# isComponent

Checks the Astro component brand without executing a candidate component.
Used by renderer discovery so probing does not run another framework's setup.

## Signatures

```ts
export declare function isComponent(value: unknown): value is Fx.Fx<RenderEvent, unknown, Services> | ((props: Record<string, unknown>, slots: Slots) => Fx.Fx<RenderEvent, unknown, Services>);
```
