AI agent builds it. superviewer shows it.
Your AI agent just made something: a screenshot, a chart, a rendered HTML page, a short clip. Now what? Usually you go dig through Finder, or open a browser tab, or switch windows to find the file. superviewer skips all of that. It's a small desktop app that sits quietly in the background and pops the result straight in front of you the moment it's ready.
Your agent builds it.
It just appears.
No digging through Finder, no opening a browser, no switching apps. A single show() call from Claude Code renders the artifact instantly in a persistent desktop viewer.
# your agent generates a chart, then: show(source="./out/revenue.html",type="html",) → rendered on your desktop in <100ms

Frequently asked questions
What is superviewer?
superviewer is a desktop viewer, built with Tauri, that instantly renders artifacts your AI agents generate: images, HTML, video, audio, markdown, and documents. Instead of hunting through Finder or opening a browser, your agent makes a single MCP call and the content appears right on your desktop. It's shipping for macOS today, with Windows and Linux on the way.
How does it work with Claude Code?
Install superviewer, open Settings → MCP, and click Install. From then on, Claude Code (or any MCP client) can call show(), show_group(), or capture() and the result renders instantly in superviewer. There's nothing else to configure.
Which file types are supported?
Images (png, jpg, gif, webp, svg, avif, and more), HTML, video (mp4, mov, webm, mkv), audio (mp3, wav, flac, m4a, ogg), and documents (pdf, markdown, txt, json, csv).
Do I need a server or cloud account?
No. superviewer is fully local and symmetric: every device both serves and views. There is no central server and no account to create.
Can I send artifacts to another machine?
Yes. You can send a rendered artifact to any peer on your network over Tailscale or LAN. Resources are served ephemerally with a configurable TTL.
Which platforms does superviewer support?
superviewer is available for macOS today. Windows and Linux builds are in progress.
