Creating personalised websites with WordPress playground

This tool generates a custom WordPress instance that runs entirely in your browser using WordPress Playground. When you enter a name and optional message, the app creates a Blueprint — a JSON configuration that tells WordPress Playground exactly how to set up the environment.

The Blueprint includes a small PHP plugin that gets injected into WordPress. This plugin hooks into the page load and displays a full-screen Apple-style welcome banner with your personalised greeting. The entire configuration (plugin code + setup instructions) is Base64-encoded and embedded directly into the URL hash fragment.

When you click "Launch Playground", it opens WordPress Playground with this encoded Blueprint — no server required. The Playground spins up a complete WordPress instance in a WebAssembly container in your browser, automatically installs and activates the greeting plugin, and displays your personalised welcome screen.

Key points:

• 🌐 100% client-side — no backend or database needed
• 📦 Self-contained URLs — all configuration lives in the link itself
• ⚡ Instant launch — WordPress boots directly in the browser via WASM
• 🔒 Private — nothing is stored or transmitted to any server
