The first AI-native web composition layer
A new way to build the web is taking shape
What if your web team could move at the speed of AI...without letting AI run wild?
P1 by Pantheon is a new operating system for the web—bringing marketers, developers, and AI agents together in one governed environment. Build with shared components and guardrails, and launch only when your site is ready for primetime.
Sandbox
This is a sandbox. The editor is real; the P1 platform behind it is simulated, and nothing you do leaves your browser.
Go ahead. Break it
This page is built on P1. As you scroll, it will hand you the editor: rewrite it, try to wreck it, publish it. We dare you. The design system controls the experience, and curates your creativity.
Chapter 1
Edit on the page
Edit your site directly in your design system, no admin screen required. In this case, you’re working within ours. Make your changes, then publish them below.
Try it: Click the headline, make it yours, then publish.
Chapter 2
Always on brand
Add components from your brand library. If you select an option outside your brand palette, the system automatically brings it back in line.
Try it: Add a callout, paint it #8A2BE2, and publish.
Chapter 3
Work on a copy of the live site
Work in a safe copy of your live site - Open a campaign workspace, make changes freely, compare them with the live site, and publish when everything looks right.
Try it: Create a new workspace and make an edit, then merge your changes into live.
Chapter 4
Get a head start with Zappy
Let Zappy, Pantheon’s agent, draft your campaign page. Review its first pass, then refine it to fit your campaign.
Try it: Ask Zappy to help you add more to the launch campaign.
