HyperFrames is a free, open-source framework for turning HTML, CSS, media, and seekable animations into deterministic MP4 videos. Use it locally with the CLI, from AI coding agents with skills, or as the rendering core behind hosted authoring workflows.

The HyperFrames Studio app is free to use as well; its Pro plan adds HeyGen's top video, image, voice and music models.

Using Claude Code, Codex, Cursor, or another coding agent? Run npx hyperframes skills update once, then ask your agent to make a video.

Quick Start

With an AI coding agent

For Claude Code, install the versioned plugin:

claude plugin marketplace add heygen-com/hyperframes

claude plugin install hyperframes@hyperframes

To enable auto-update for the hyperframes marketplace, run claude in a terminal in your project. In Claude Code's terminal UI, run /plugin, then select Marketplaces → hyperframes → Enable auto-update. Afterward, use /hyperframes:hyperframes. See the plugin guide for Copilot, VS Code, Cursor, Gemini CLI, updates, and migration.

For standalone skills (including OpenCode), use:

npx skills add heygen-com/hyperframes

The picker opens with nothing pre-selected — the Core Skills group is all you need; /slideshow, /remotion-to-hyperframes and /figma install on demand. Without the picker (a script or a CI job), npx hyperframes skills update installs exactly the core set, whereas skills add --all installs all 9 published skills. The six repo-internal skills under .claude/skills / .agents/skills are excluded by default. For the full published set use npx hyperframes skills.

skills add resolves the skills.sh registry blob, which can lag main by hours. npx hyperframes skills update installs the skills from the release tag that matches your CLI version, so they match the CLI that runs them.

Run project-local installs from your video project's directory. From a HyperFrames checkout, use npx hyperframes skills update for a global install instead: a project-local installer target can overlap the tracked skills/ source and overwrite uncommitted edits. See contributor setup.

Try a prompt like:

Using /hyperframes, create a 10-second product intro with a fade-in title, a background video, and subtle background music.

The skills teach agents the HyperFrames production loop: plan the video, write valid HTML, wire seekable animations, add media, lint, preview, and render. They work with Claude Code, Codex, Cursor, Gemini CLI, IBM Bob, and other coding agents that support skills.

Skills

HyperFrames ships 9 skills. Make any video by asking for it; the /hyperframes skill carries the contract and the references (film, captions, overlays, motion, look). Read it first.

For standalone installation, default to the core set (/hyperframes, /hyperframes-cli, /hyperframes-registry, /media-use, /reverse-any-video, /style-sampling). npx hyperframes skills update installs exactly that from anywhere; the interactive picker (npx skills add heygen-com/hyperframes) lists it as the "Core Skills" group, nothing pre-selected. The picker is interactive-only — a non-interactive or agent run without --skill installs all 9. Use npx skills add heygen-com/hyperframes --all to install the complete published set deliberately (skips the picker), or npx skills add heygen-com/hyperframes --skill for just one (bare name, no leading /).

Standalone installs stay lean after that: npx hyperframes init installs the core set only when it is missing and never touches a skill you already have (npx hyperframes skills update refreshes them, and never removes one); /figma, /slideshow and /remotion-to-hyperframes install on demand with npx hyperframes skills update . Nothing re-pulls the full set behind your back.

Plugin packages

Plugins bundle the full skill catalog and use their agent's update manager. bun run package:agent-plugin builds the committed portable ZIP, source metadata, and SHA-256 checksum. See the maintainer checklist.

Upload to Codex

Build the upload-ready Codex plugin archive from the committed HEAD version of the manifest, brand assets, and skills:

bun run package:codex-plugin

This writes dist/hyperframes-plugin.zip with a hyperframes/ root folder and fails if the archive exceeds Codex's 100 MB upload limit.

Core set

On demand

For visual design handoff workflows, see the Claude Design guide and Open Design guide.

Manually with the CLI

npx hyperframes init my-video

cd my-video npx hyperframes preview # preview in browser with live reload npx hyperframes render # render to MP4

Requirements: Node.js 22+, FFmpeg
