description: "Create HyperFrames video drafts in Open Design — the open-source, BYOK Claude-Design alternative — then refine in any AI coding agent."
---

[Open Design](https://github.com/nexu-io/open-design) is an open-source, local-first alternative to Claude Design. It runs on your laptop with `pnpm tools-dev`, deploys the web layer to Vercel, and delegates to whichever coding-agent CLI you already have on your `PATH` (Claude Code, Codex, Cursor Agent, Gemini CLI, OpenCode, Qwen, Copilot, Hermes, Kimi, Pi) — or to any OpenAI-compatible BYOK endpoint.

Open Design produces a **valid first draft** of a HyperFrames composition — palette, scene content, GSAP entrance tweens, mid-scene activity, and shader transitions. You then download the project and refine in any AI coding agent with linting and live preview.

## Get started

<Steps>
  <Step title="Download the instruction file">
    Open [`open-design-hyperframes.md`](https://github.com/heygen-com/hyperframes/blob/main/docs/guides/open-design-hyperframes.md) on GitHub and click the download button (↓) to save it.
  </Step>
  <Step title="Run Open Design locally">
    ```bash
    git clone https://github.com/nexu-io/open-design.git
    cd open-design
    pnpm install
    pnpm tools-dev run web
    # open the web URL printed by tools-dev
    ```
  </Step>
  <Step title="Drop the file into a skill, or attach it to chat">
    **Recommended:** copy `open-design-hyperframes.md` to `skills/hyperframes-handoff/SKILL.md` inside the Open Design repo. The daemon auto-discovers it on the next request and exposes it as a skill in the picker. **Or:** start a new chat and attach the file directly — Open Design reads attachments natively.
  </Step>
  <Step title="Describe your video">
    Pick the `hyperframes-handoff` skill (or your active prototype skill), pick a design system or visual direction, and type the brief. Include screenshots, brand assets, or a palette if you have them.
  </Step>
  <Step title="Save the project to disk">
    Open Design writes `index.html`, `preview.html`, `README.md`, and a `DESIGN.md` snapshot into `.od/projects/<id>/`. Click **Save to disk** or download as a project ZIP.
  </Step>
  <Step title="Refine in any AI coding agent">
    The Open Design project folder is already a real on-disk working directory. Hand it off to Claude Code, Cursor, Codex, or any agent with terminal access:
    ```bash
    cd .od/projects/<id>
    npx skills add heygen-com/hyperframes   # install skills (one-time)
    npx hyperframes lint                     # should pass with zero errors
    npx hyperframes preview                  # open the studio
    ```
  </Step>
</Steps>

<Tip>
  **Drop into `skills/`, don't paste into chat.** Open Design's daemon reads `SKILL.md` files at request time and injects the side files (templates, references) automatically. A pasted URL or chat attachment works, but the skill path gives you the full pre-flight pipeline (template injection + 5-dimensional self-critique gate).
</Tip>

## Which setup to use

| Surface                                | Recommended setup                                                                                                                                                            |
| -------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Open Design (open-source)              | Drop [`open-design-hyperframes.md`](https://github.com/heygen-com/hyperframes/blob/main/docs/guides/open-design-hyperframes.md) into `skills/hyperframes-handoff/SKILL.md`   |
| Claude Code                            | `npx skills add heygen-com/hyperframes`, then use `/hyperframes`                                                                                                             |
| Cursor / Codex / Gemini CLI            | `npx skills add heygen-com/hyperframes`                                                                                                                                       |
| Claude Design (closed-source)          | Attach [`claude-design-hyperframes.md`](https://github.com/heygen-com/hyperframes/blob/main/docs/guides/claude-design-hyperframes.md) to your chat                          |

## How it works

The instruction file gives Open Design **pre-valid HTML skeletons** — the structural rules (data attributes, timeline registration, scene visibility, preview token forwarding) are already embedded. Open Design fills in the creative work:

1. **Palette + typography** — driven by the active `DESIGN.md` (Open Design ships 72 systems out of the box, plus 5 deterministic visual directions when no brand is named) bound onto `:root`
2. **Scene content** — text, images, layout inside `.scene-content` wrappers
3. **Animations** — GSAP entrance tweens and mid-scene activity
4. **Transitions** — hard cuts for most scenes, shader transitions at 2-3 key moments

Open Design's [5-dimensional self-critique](https://github.com/nexu-io/open-design/blob/main/apps/web/src/prompts/discovery.ts) runs before emission, so the artifact arrives lint-clean and your coding agent can start refining immediately without structural fixes.

## Example prompts

  <Card title="Feature announcement">
    ```text
    Use the hyperframes-handoff skill. I just shipped dark mode for my app.
    Make me a 15-second Instagram reel announcing it.

    - App name: Taskflow
    - Primary color: #6C5CE7
    - The vibe is clean, minimal, dark
    - Key stat: "47% of users requested this"
    ```
  </Card>
  <Card title="Founder pitch (BYOK with your own CLI)">
    ```text
    Use the hyperframes-handoff skill on Codex CLI. 25-second LinkedIn video.

    Problem: Sales teams waste 3 hours/day on manual CRM updates.
    Solution: AutoCRM — AI that logs every call, email, and meeting.
    Traction: 200+ teams, $1.2M ARR, 18% MoM growth.
    CTA: autocrmhq.com

    Use the Linear design system. Professional but not corporate.
    ```
  </Card>
  <Card title="Brand-driven (use one of the 72 design systems)">
    ```text
    Use the hyperframes-handoff skill. Design system: Stripe. 10-second reel.
    One big number: "$4.2 billion processed in Q1 2026"

    Dark background, the number animates up from zero. Subtle, confident.
    End with logo placeholder and "stripe.com"
    ```
  </Card>
  <Card title="Sparse brief (let it ask)">
    ```text
    Use the hyperframes-handoff skill. 30-second launch video for Orbit.
    ```

    Open Design's `RULE 1` always opens with a `<question-form>` before emitting code, so a sparse brief turns into one short question form (surface · audience · tone · brand · scale) instead of an AI-freestyle render.

## What to include in your prompt

Open Design reads inputs in this order of reliability: **active DESIGN.md > attachments > pasted content > web research > URLs**.

| Input type | What it gives Open Design |
| --- | --- |
| Active design system (72 shipped, switchable from picker) | Full 9-section spec (color, typography, spacing, layout, components, motion, voice, brand, anti-patterns) — strongest source |
| Screenshots / PDFs / brand guides | Palette, typography, UI patterns, tone — read by the agent natively |
| Pasted hex codes, typefaces, copy | Authoritative for what they cover |
| Brand name (well-known) | Open Design can `WebFetch` blogs, press, Wikipedia |
| SPA URL (React/Vue homepage) | Returns near-empty shell — pivot to blog/press instead |

The more specific your prompt, the better the output. Pick a design system or visual direction up front, then describe content.

## Why use Open Design vs. Claude Design

| | Claude Design | **Open Design** |
| --- | --- | --- |
| License | Closed | Apache-2.0 |
| Cost | Pro / Max / Team | BYOK (free with your own CLI / API key) |
| Form factor | Web (claude.ai) only | Web app + local daemon (or deploy to Vercel) |
| Agent runtime | Anthropic only (Opus 4.7) | 10 CLI adapters + OpenAI-compatible BYOK proxy |
| Skills | Proprietary | 31 file-based `SKILL.md` bundles, droppable |
| Design systems | Proprietary | 72 shipped `DESIGN.md` systems |
| Filesystem-grade workspace | ❌ | ✅ Real `cwd`, real `Read` / `Write` / `Bash` / `WebFetch` |

If you want the Claude Design loop without lock-in, Open Design is the same artifact-first mental model — open, local, BYOK.

## Known limitations

- **Render still happens locally** — Open Design produces the HTML; `npx hyperframes render` and HDR encoding still need FFmpeg + Node 22+ on your machine.
- **In-pane preview is sandboxed iframe** — full browser playback is reliable; for frame-accurate scrubbing use `npx hyperframes preview` after handoff.
- **Shader passthrough requires WebGL** — same as the Claude Design path; Open Design's iframe sandbox supports it.
- **Skill pre-flight is daemon-side** — if you bypass the skill picker and paste raw HTML into chat, you lose the side-file injection and 5-dim critique gate. Use the skill.

## The handoff to your coding agent

Open Design's project folder is the agent's `cwd`. There's no "export then re-import" step — open Claude Code, Cursor, Codex, or any AI coding agent against the same directory:

```bash
cd .od/projects/<your-project-id>
npx skills add heygen-com/hyperframes   # one-time setup
npx hyperframes lint                     # verify structure
npx hyperframes preview                  # open the studio
```

Then iterate the same way as the Claude Design path:

- "Make scene 3's entrance snappier"
- "Add a counter animation to the stat in scene 5"
- "Tighten the pacing — scenes 4 and 6 feel too long"
- "Change the shader on transition 2 to glitch"
