HyperFrames is an open-source framework that turns HTML into video. You make the request; an AI agent builds an editable project; HyperFrames plays or renders it.

## What can it make?

Every tile below is a finished HyperFrames film. Open one to watch it with sound.

<ShowcaseWall />

## Three things to know

**Agent-built.** You describe the video; the agent writes the HTML, CSS, and JavaScript. You do not need to write code for this path.

**Editable.** The result is a project folder, not a flattened black box. An agent, Studio, and your own tools can work on the same files.

**Reliable render.** HyperFrames asks the project for each exact frame instead of
depending on live playback, so a slow machine does not drop moments from the
finished video.

## Make one
