summary

Fast, disposable WordPress instances in the browser or locally via CLI, with auto-mounting, version switching, and Xdebug debugging.

  • Spin up ephemeral WordPress sites in WebAssembly with SQLite; supports WordPress 6.9+ and PHP 7.2.24+, with quick version switching for compatibility testing.
  • CLI commands include server (auto-mount plugins/themes), run-blueprint (scripted setup), and build-snapshot (shareable ZIP exports) via Node.js 20.18+.
  • Auto-detect and mount local plugin or theme

WordPress Playground

When to use

  • Spin up a disposable WordPress to test a plugin/theme without full stack setup.
  • Run or iterate on Playground Blueprints (JSON) locally.
  • Build a reproducible snapshot of a site for sharing or CI.
  • Switch WP/PHP versions quickly to reproduce issues.
  • Debug plugin/theme code with Xdebug in an isolated Playground.

Inputs required

  • Host machine readiness: Node.js ≥ 20.18, npm/npx available.
  • Project path to mount (--auto-mount or explicit mount mapping).
  • Desired WP version/PHP version (optional; defaults to latest WP, PHP 8.3).
  • Blueprint location/URL if running a blueprint.
  • Port preference if 9400 conflicts.
  • Whether Xdebug is needed.

Procedure

0) Guardrails

  • Playground instances are ephemeral and SQLite-backed; never point at production data.
  • Confirm Node ≥ 20.18 (node -v) before running CLI.
  • If mounting local code, ensure it is clean of secrets; Playground copies files into an in-memory FS.

1) Quick local spin-up (auto-mount)

cd <plugin-or-theme-root>
npx @wp-playground/cli@latest server --auto-mount
  • Opens on http://localhost:9400 by default. Auto-detects plugin/theme and installs it.
  • Add --wp=<version> / --php=<version> as needed.
  • For classic full installs already present, add --skip-wordpress-setup and mount the whole tree.

2) Manual mounts or multiple mounts

  • Use --mount=/host/path:/vfs/path (repeatable) when auto-mount is insufficient (multi-plugin, mu-plugins, custom content).
  • Mount before install with --mount-before-install for bootstrapping installer flows.
  • Reference: references/cli-commands.md

3) Run a Blueprint (no server needed)

npx @wp-playground/cli@latest run-blueprint --blueprint=<file-or-url>
  • Use for scripted setup/CI validation. Supports remote URLs and local files.
  • Allow bundled assets in local blueprints with --blueprint-may-read-adjacent-files when required.
  • See references/blueprints.md for structure and common flags.

4) Build a snapshot for sharing

npx @wp-playground/cli@latest build-snapshot --blueprint=<file> --outfile=./site.zip
  • Produces a ZIP you can load in Playground or attach to bug reports.

5) Debugging with Xdebug

  • Start with --xdebug (or --enable-xdebug depending on CLI release) to expose an IDE key, then connect VS Code/PhpStorm to the host/port shown in CLI output.
  • Combine with --auto-mount for plugin/theme debugging.
  • Checklist: references/debugging.md

6) Version switching

  • Use --wp= to pin WP (e.g., 6.9.0) and --php= to test compatibility.
  • If feature depends on Gutenberg trunk, prefer the latest WP release plus plugin if available; Playground images track stable WP plus bundled Gutenberg.

7) Browser-only workflows (no CLI)

  • Launch quick previews with URL fragments or query params:
    • Fragment: https://playground.wordpress.net/#<base64-or-json-blueprint>
    • Query: https://playground.wordpress.net/?blueprint-url=<public-url-or-zip>
  • Use the live Blueprint Editor (playground.wordpress.net) to author blueprints with schema help; paste JSON and copy a shareable link.

Verification

  • Verify mounted code is active (plugin listed/active; theme selected).
  • For blueprints/snapshots, re-run with --verbosity=debug to confirm steps executed.
  • Run targeted smoke (e.g., wp plugin list inside Playground shell via browser terminal if exposed) or UI click-path.

Failure modes / debugging

  • CLI exits complaining about Node: upgrade to ≥ 20.18.
  • Mount not applied: check path, use absolute path, add --verbosity=debug.
  • Blueprint cannot read local assets: add --blueprint-may-read-adjacent-files.
  • Port already used: --port=<free-port>.
  • Slow/locked UI: disable --experimental-multi-worker if enabled; or enable it to improve throughput on CPU-bound runs.

Escalation

  • If PHP extensions or native DB access are required, Playground may be unsuitable; fall back to full WP stack or wp-env/Docker.
  • For browser-only embedding or VS Code extension specifics, consult the upstream docs: https://wordpress.github.io/wordpress-playground/

How to use wp-playground on Cursor

AI-first code editor with Composer

1

Prerequisites

Before installing skills in Cursor, ensure your development environment meets these requirements:

  • Cursor installed and configured on your development machine
  • Node.js version 16.0+ with npm package manager (verify with node --version)
  • Active project directory or workspace where you want to add wp-playground
2

Execute installation command

Execute the skills CLI command in your project's root directory to begin installation:

$npx skills add https://github.com/wordpress/agent-skills --skill wp-playground

The skills CLI fetches wp-playground from GitHub repository wordpress/agent-skills and configures it for Cursor.

3

Select Cursor when prompted

The CLI will show a list of available agents. Use arrow keys to navigate and space to select Cursor:

◆ Which agents do you want to install to?
│ ── Universal (.agents/skills) ── always included ────
│ • Amp
│ • Antigravity
│ • Cline
│ • Codex
│ ●Cursor(selected)
│ • Cursor
│ • Windsurf
4

Verify installation

Confirm successful installation by checking the skill directory location:

.cursor/skills/wp-playground

Reload or restart Cursor to activate wp-playground. Access the skill through slash commands (e.g., /wp-playground) or your agent's skill management interface.

Security & Verification Notice

We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.

Skills execute code in your development environment. Always verify the publisher's identity, review recent commits, and test in isolated environments before production deployment.
