Comparison
HyperFrames is for developers who want an open-source HTML-to-video framework they can script and run anywhere. Truca is for Mac users who want their agent to build the animation while they direct it on a storyboard and a timeline, see every format side by side, then share it for client comments.
Facts about HyperFrames last checked on November 8, 2026 · Sources
Same starting point, HTML scenes built by an agent. Truca wraps it in a studio you direct, from the first storyboard to the client’s last comment.
Unlike HyperFrames, where a composition has one width and height, a Truca scene holds its 16:9, 9:16, 4:5 and 1:1 versions. Switch to All formats and they sit next to each other, each at its own resolution, playing together as you edit. Change them all at once, or one with This format only.
Truca’s MCP server gives Claude Code, Codex, Cursor, Gemini CLI or VS Code 40 tools that work on the open project. Every change shows up in the app as it happens, and the engine checks it first: an invalid change is refused and your file stays intact.
Plan your scenes in the Storyboard, then cut them on a timeline with chapters, music and sound effects. Animations are data, not scripts, so you can fine-tune any timing by hand in the scene editor.
Share a private link without exporting first: the video plays in the browser. Clients pin comments on the frame, they land in the app, and your agent can read them, see the frame and reply.

|---|---|---|
| Formats while you edit | Truca stands out: Every format of a scene side by side (16:9, 9:16, 1:1, 4:5…), each at its own resolution, playing together on one timeline; edit them all at once or one at a time | A composition has one width and height; the documentation describes no side-by-side view of several formats |
| Platform | Native Mac app, macOS 14 or later, Apple silicon | Open-source framework and CLI (Node.js 22+, FFmpeg); Studio app for Mac, Windows and Linux |
| How scenes are made | Truca stands out: Your agent builds HTML and CSS scenes through MCP tools. Animations are data played by the engine: no animation script to write or debug | Your agent writes HTML, CSS and JavaScript compositions, timed with data attributes and a paused animation timeline (GSAP, CSS, Lottie, Three.js…) |
| AI agents | MCP server with 40 tools, connected from the app to Claude Code, Claude, Codex, Cursor, Gemini CLI or VS Code | Agent skills for Claude Code, Codex, Cursor, Gemini CLI and others; hosted MCP connector for Claude and ChatGPT, in beta |
| Editing by hand | Truca stands out: Storyboard, scene editor and a timeline with chapters, music and sound effects | Studio: chat, preview and editor in one window; edit by typing, pointing, drawing or commenting |
| Client review | Truca stands out: Private link that plays the video in the browser, no export needed; optional password and expiry; comments come back to the app and to your agent | Review page made from the latest MP4 export, with comment or view-only access; sharing needs a HeyGen account |

We’d rather you pick the right tool. HyperFrames makes sense if one of these matters most to you.
You work on Windows or Linux. Truca is Mac only; the HyperFrames CLI and Studio run on all three.
You want open source to build on. HyperFrames is Apache 2.0, with a CLI you can script and render on your own servers or AWS Lambda.
You need HeyGen’s generative media. AI voices, avatars and video clips come with a HeyGen account.
You only use a chat app. Its hosted connector makes videos from Claude or ChatGPT with nothing to install.
Connect Claude Code, Codex or Cursor from the app, open the sample project and ask your agent for a first storyboard.
Yes, on a Mac. Both turn HTML scenes made by an AI agent into video. Truca adds a storyboard, a timeline with music and chapters, and review links whose comments reach your agent.
Yes. Truca connects to them over MCP from its Connect an agent sheet, as well as to Claude, Gemini CLI and VS Code.
No. Truca is a native Mac app and needs macOS 14 or later on Apple silicon.
Truca is free during the beta.
