Structure Viewer – File Explorer & AI Context Builder for WordPress Plugin Directory

Structure Viewer is a WordPress file explorer and AI context builder for developers — browse, inspect, view source code, and export the complete file structure of any installed plugin or theme, directly from your WordPress admin dashboard.

No FTP, no cPanel, no server access needed. Open any file, read its source code with syntax highlighting, search across your entire codebase, and export the full file tree as TXT, JSON, XML, PDF, or clipboard copy — all without leaving WordPress.

And if you work with any AI coding tool — ChatGPT, Claude, Cursor, Copilot, Gemini, or anything else — Structure Viewer is the missing first step. Export your plugin’s complete structure as ready-to-use AI context in one click, and give your AI the full codebase map before you ask it anything.

🤖 Built for AI-Assisted Development Modern coding workflows look different than they did two years ago. You’re working alongside an AI, and your AI works better when it has structural context. Structure Viewer is designed for exactly that workflow:

Tree-format exports purpose-built for LLM context windows — clean ASCII, no markdown noise, token-efficient

Works with any AI tool — ChatGPT, Claude, Cursor, Copilot, Gemini, Perplexity, or any other chat or coding assistant

One-click clipboard copy — emoji tree format that pastes into any AI chat with perfect alignment

Filter before you export — exclude node_modules, vendor, build artifacts, or anything you don’t want bloating your context

Read source inline — open any file in the browser modal, copy the snippet you need, paste into your AI conversation

Auto-redact secrets — opt-in masking of API keys, tokens, passwords, AWS / Stripe / GitHub keys, JWTs and PEM private keys before content leaves the server — paste into any AI tool without leaking credentials

Pro: Comparator — diff two versions of a plugin and feed only the changed lines to your AI for targeted code review

Pro: FlatPack — extract just the PHP, just the JS, or just the CSS from any plugin and hand the AI a focused codebase

WP-CLI exports — script structure dumps directly into your AI agent’s working directory

Stop pasting one file at a time. Give the AI the whole map first, then ask better questions.

🗂️ File Explorer See exactly what is inside every plugin and theme:

Interactive tree view — expandable folders with icons for every file type (PHP, JS, CSS, images, JSON, XML, and more)

Searchable item picker — switch between All Plugins, individual plugins, All Themes, and individual themes instantly

Live tree search — type to filter files in real time, jump between matches with next/prev navigation

All-mode plugin filter — when viewing All Plugins or All Themes, the live search filters the plugin or theme list by name so you can find the one you want fast

File type tag strip — one click to show only PHP files, only CSS, only images — whatever you need

File size and modification dates — see when each file was last changed, toggle on/off

Recently Viewed panel — jump back to any file or folder you have already opened

📄 File Viewer Click any file to read it right there in your browser:

Inline modal with syntax highlighting for all common languages

File metadata: size, line count, last modified timestamp

Auto-redact secrets badge — shown in the modal when redaction is active so you know the displayed content has been sanitised

Fullscreen mode for reading long files without scrolling the page

One-click download — get any file with the correct MIME type and original filename preserved

🔍 Search Find any file across your entire plugin or theme in seconds:

Real-time search — results appear as you type, no page reloads

Extension search — prefix with a dot to filter by type: .php, .js, .css, .json

File type dropdown for quick narrowing

Results show full relative path, file size, and last modified date

📤 Export Share or document your plugin structures in any format:

TXT — clean ASCII tree, perfect for documentation, tickets, and AI context windows

JSON — nested structure with file sizes and timestamps for programmatic use

XML — standardized hierarchical format

PDF — formatted document with header, page numbers, and automatic page breaks

Clipboard — one-click emoji tree copy for pasting into Slack, Notion, or GitHub

📊 Dashboard Your WordPress file ecosystem at a glance:

Stat tiles for total plugins, active/inactive split, total themes, and total files indexed

Largest plugins table — instantly see which plugins are heaviest with file count and size bars

WordPress environment strip: WP version, PHP version, active theme, site URL

⚙️ Settings Make it yours:

Dark mode / Light mode — toggle instantly from the plugin header or apply via Settings; rendered server-side with no flash on load

Accent color picker — Emerald (default), Violet, Blue, Amber, or Rose

Auto-redact secrets on export (new in 2.2.2) — opt-in toggle that masks credentials in viewed and downloaded file content

Exclude hidden files, system directories, and custom patterns (node_modules, .git, vendor)

Settings auto-save with instant confirmation toast

💻 WP-CLI Automate structure exports from the command line:

wp structure-viewer export plugin <folder-name> wp structure-viewer export theme <folder-name> wp structure-viewer list plugins wp structure-viewer list themes

🚀 Structure Viewer Pro Unlock two powerful Pro tools for developers who need to go deeper.

🔀 Comparator — Know Exactly What Changed

Ever updated a plugin and wondered what actually changed? Comparator shows you a precise, color-coded, line-by-line diff between any two versions — so you can audit updates, review customizations, and catch unwanted changes before they cause problems.

Compare two plugin ZIPs side by side

Compare an installed plugin or theme against any uploaded ZIP

Compare two individual files for a targeted spot-check

Added lines in green, removed in red, changed lines clearly highlighted

Works on large plugins and minified CSS/JS files — auto-tokenizes before diffing

Expand/collapse per-file diff blocks to focus on what matters

📦 FlatPack — Extract Only What You Need

Need just the CSS from a plugin? Or all the PHP files for a code review? FlatPack extracts any plugin or theme ZIP and flattens it into a single, clean download — no nested folders, no hunting through directory trees.

Upload any plugin or theme ZIP and see all its files in a live preview instantly

Filter by PHP, CSS and JS, images, or any custom extension — preview updates live

Only the filtered files are included in the output ZIP

Smart collision-safe naming: duplicate basenames get a folder prefix automatically

Download a single flat ZIP in seconds

Upgrade to Pro from within the plugin — Settings → License → Upgrade to Pro.
