Apps, sites, artifacts. Built by your agent, hosted by a URL.

Whatever you need built for the moment, your agent makes it. Pane hosts it by URL and feeds your answer back, no app to install on either side.

Frequently asked questions

How agent-built, URL-hosted personal software works, and what you can build with it.

What is Pane?

Pane is a round-trip UI channel between AI agents and humans. Your coding agent builds a rich interactive UI, like a form, dashboard, tool, or HTML artifact. Pane hosts it at a URL, and when you interact with it your answer comes back to the agent as structured data. No GUI host app is needed on either side.

Can my AI agent build me an app or tool?

Yes. Tell your agent to use Pane and it builds the app, dashboard, or page you need for the moment and hands you a URL: a meal planner, a budget reconciler, a baby-feeding log, a habit tracker, a reading list, an event page, a portfolio, a slide presentation, or a data visualization. It's personal software your agent builds on demand.

How do I host an HTML artifact?

Have your agent build the HTML and hand it to Pane, and you get a shareable URL back instantly. No build step, no deploy pipeline, and no app to install. It's the fastest way to host an HTML artifact, a landing page, an interactive report, or a one-off microsite.

Does Pane work with Claude Code, Cursor, and other agents?

Yes, any coding agent. Install the skill with npx skills add aerolalit/paneui --skill pane; it auto-detects Claude Code, Cursor, Codex, Gemini, GitHub Copilot, Windsurf, and Continue. Pane runs inside your agent, not in the browser.

How does the agent get my answer back?

When a pane captures input, like a form submit, a picker, a button, or an approval, Pane delivers it back to your agent as structured data over WebSocket, polling, or webhook. That's the round-trip: the agent shows you a UI and acts on what you do with it.

Do I need to install an app or sign up?

No app on either side and no signup to try it. Your agent talks to a small relay over outbound calls only, with no inbound port and no public address of its own. The CLI needs Node 20+.

Is Pane open source? Can I self-host it?

Yes. Pane is open-core and MIT licensed. Self-host the relay with a single Docker container backed by SQLite, or use the hosted relay at relay.paneui.com. The source lives on GitHub.

What can I build with Pane?

Anything that's better seen than described: forms, pickers, dashboards, document or diff review, approvals, status pages your agent updates, multi-step wizards, and file uploads. Plus personal apps like meal plans, habit trackers, trip packing lists, and chore charts, and shareable artifacts like event pages, portfolios, presentations, digital postcards, and visualizations.
