Debug Suite

Debug Suite is a developer toolkit that puts the tools you normally reach for over SSH right inside wp-admin: run PHP against the live site in a browser console, read the debug log without touching FTP, watch outgoing mail, and browse auto-generated docs for every REST endpoint your site exposes. Everything is one click away from the admin bar, on any admin screen.

🚀 Key Features

• Query Console — a PHP REPL in your browser

  • Run PHP against your live WordPress runtime, right from the admin bar. No SSH, no WP-CLI, no scratch plugin files.
  • Monaco editor with syntax highlighting, plus a split output pane that captures return values, dump() output and execution time.
  • Save frequently used snippets and re-run them in one click; recall what you ran before from the local history.

• Debug Console wherever the admin bar is

  • A “Debug” item in the admin bar opens a full-screen overlay with the Query Console and the Debug Log as two tabs — in wp-admin and on the front end alike.
  • Stay on the page you are debugging — no navigating away, and the overlay remembers whether you left it open.

• Smart Debug Log Viewer

  • Read your WordPress debug logs without ever leaving the dashboard or using FTP.
  • Switch between the raw file and a parsed view; filter by severity (warnings, notices, errors, fatals) and search.
  • Auto-discovers the log files it can find, loads long logs incrementally, and clears them in one click.

• Debug Constants Management

  • Toggle WP_DEBUG and WP_DEBUG_LOG from Settings — Debug Suite writes them straight into wp-config.php for you.
  • No FTP, no code editor, and no guessing which debug constants are currently active on the site.

• Outgoing Email Log (optional)

  • Never wonder if a user received a receipt or notification again.
  • Keep a complete history of every email sent by your WordPress site.
  • Quickly view recipients, subject lines, contents, and delivery status at a glance.

• Interactive API Documentation (on by default, switchable in Settings)

  • Explore your site’s REST API endpoints at /debug-suite/api/docs through a beautiful, easy-to-read visual interface.
  • Automatically generates OpenAPI documentation for every registered REST namespace, with bearer-token auth support.
  • Perfect for helping developers and external services understand how to connect to your site.

• Lightning-Fast & Customizable

  • Only use what you need! Turn optional tools on or off with a single click in Settings.
  • Optional features create their database tables only when you activate them — nothing is provisioned up front.
  • Modern React/TypeScript interface, loaded only on Debug Suite screens, so your admin stays fast.

• Built to extend

  • PHP: service container, Hookable services and a debug_suite_localized_data filter for third-party integrations.
  • JavaScript: register your own admin pages through the debugSuite.routes filter and inject UI via Slot/Fill.
