WP Debug Toolkit

Cover the Most Common
WordPress Fire Drills

Error Log Viewer

A standalone viewer that lets you inspect WordPress errors and logs even when wp-admin won’t load

Works even when wp-admin won’t load (standalone Viewer, separate from WordPress login)
Fast search + filtering so you can find the signal in noisy logs
Open file/line context directly from an entry to confirm the source

Easily Access Your WordPress Logs

01

Query Viewer

Record database queries for each page load so you can spot slow queries, repeated queries, and the code paths that trigger them

Logs stored on disk (JSON), not in WordPress database tables
Flags slow queries, duplicate patterns, and potential N+1 loops
Per-request session summaries + best-effort attribution (plugin/theme/core)

Understand Your Database Queries

02

Bought it, looks great... I’d also love for it to enable or disable WP_DEBUG for me via a toggle. It’s awesome that it works even when there’s a fatal error.

Tom DeBello

Developer

No-brainer, picked this up right away.

This is one of those tools you never knew you needed until you saw it. It's a true game changer for me and my development team. We'll be using this a lot, and I expect many people will too

I'm not a dev really just, I suppose a 'Facilitator' for my customers but I understand how things work and I love learning more stuff, your plugin has helped facilitate that and more!

Its cut down my workload by probably 20% so well done

William Cromwell

Agency Owner

This plugin quietly became one of my must-haves. I use it for my dev work, and it helps me catch issues rightaway as they happen. Total time-saver.

Yep - nice one - Got it. - The log view being able to be used when the site has white screened is a MUST HAVE feature - especially for those of us doing quite a bit of PHP work..

David Dennison

@Searchriot

You can see what plugins are constantly throwing errors. Even if they aren't affecting anything, lots of errors might tell you that you need to find a replacement - before it does affect something. $60 well spent! And it's a lifetime deal! Happy building

Denis Guerrero

Developer

Just enabling WP_DEBUG without FTP is already a win for me. Getting the logs in a beautiful, clear UI with all the other bells and whistles is just a huge bonus. I'm not even a developer and this is saving my bacon on a daily basis

Easy on the eyes

Both user and developer friendly UI and theme switcher so debugging always feels familiar to you.

Flexible Filters

Cut through unwanted notices and warnings using the built in filters and focus only on what matters.

Independent Viewer App

Even if WordPress crashes out completely, the Viewer App will still work and show you the errors.

Powerful File Viewer

Not only read the error, but check the entire file and get full context on where your code was called from and why.

Keyboard Shortcuts

Either click away, or use system-wide hotkeys to navigate the app. It's right on your fingertips.

Error Highlight

Easily identify the different levels and errors in a clear way. This will help you understand and fix bugs faster.

Real Time Logging

No need to wait, refresh or dig through your files to read the logs. The Viewer App displays them instantly.

Crash Recovery System

Your site crashed and got locked out of WordPress? Not an issue. Disable plugins and themes and log back in.

Want More?

We'd love to hear your ideas. If you think there is a missing feature, just say the word and we'll try to get it shipped.

Slow Query Detection

Instantly spot database bottlenecks. Queries exceeding your threshold are automatically flagged for review.

N+1 Pattern Alert

Identify inefficient loops running the same query hundreds of times. A silent performance killer, now made visible.

Low-Overhead Logging

File-based logging has a low impact on your database. Monitor production sites without slowing them down.

Component Attribution

Know exactly who to blame. See if a query came from Core, a specific Plugin, or your Theme at a glance.

Keyboard Shortcuts

Use quick keys to view stack traces, copy SQL, or focus the search bar without touching your mouse.

Instant File Viewer

Don't just see the query, see the code. Use the viewer to inspect the exact PHP lines that triggered the database call.

Live Dashboard

Watch queries appear in real-time with dashboard auto-refresh. Perfect for monitoring checkout or complex flows.

Complexity Scoring

Not all queries are equal. We analyze SQL structure (JOINs, subqueries) to rate query complexity on a 1-10 scale.

Data Export

Need to share with a team? Export your query logs to CSV, JSON, or TSV for external analysis or reporting.

Instant Alerts

Get notified the moment a critical error occurs. Be the first to know so you can fix it before users complain.

Dual-Channel Delivery

Standard email failed? No problem. We automatically fallback to native PHP mail to ensure your alert gets through.

Smart Rate Limiting

Prevent inbox flooding. We intelligently group repeated errors so you get one meaningful alert, not 5,000.

Recovery Integration

Enhanced emails include a direct link to the log viewer and WP Recovery, so you can log in safely and troubleshoot.

White Labeling

Make it yours. Add your agency logo and brand colors to every alert email for a professional client experience.

Memory Protection

We reserve emergency memory to ensure alerts can still be sent even during memory exhaustion crashes.

Custom Thresholds

You decide what's urgent. Configure alerts for Fatal Errors only, or include Warnings and Notices for dev sites.

Custom Content

Direct clients to the right place. Add custom support links or instructions to every error report.

Race-condition proof

Our locking system ensures that 50 concurrent visitors crashing the site only triggers one email.

Frequently Asked Questions

Debug WordPress Sites
Doesn't Need to Be Annoying or Hard

But we understand you may have some questions on how would WP Debug Toolkit help you streamline your debug and developing process, how it works, and other commonly asked questions you may have. For all of that and more, please read below, and be sure to contact us if what you're looking for isn't there!

How dos it work?

WP Debug Toolkit contains a Viewer App that gets installed on your server. It'll allow you to access the WordPress logs without relying on WordPress or any of its hooks. This way, even if WordPress crashes out, you'll always know why that happened by accessing the Viewer App (needs to be previously installed).

Is this a WordPress plugin or a standalone app?

Both. You need to install WP Debug Toolkit as a WordPress plugin. It'll have a number of tools you can use from the WordPress Admin, but its main purpose is to allow you to install the Viewer App, which works independently from WordPress and its where all the magic actually happens.

Do you offer lifetime deals?

Yep. Nowadays people say LTDs are no longer sustainable, but we think differently. We developed WP Debug Toolkit as an internal tool and now we can't imagine a world without it, so we're commited to it for life.

Do you have a roadmap?

Yes, we do have a list of features planned for the future and we're constantly working on improving WP Debug Toolkit. We use our own tool to work on its own development and many other projects, and when we need something, we write it down and start working on it. We also encourage you to pitch us your wildest dreams in terms of desired features. We'll do our best to make them happen.

Do you have refunds?

Honestly? We don't think you'd ever go back to debugging like in the old ages after you've given WP Debug Toolkit a try, but if for whatever reason you're not happy with it, you can return it within 30 days for a full, no questions asked refund.

Want to try it first?

We can't offer you a free trial, but we do have a great demo where you can testdrive all features for free for seven days and (spoiler alert) even get a discount on your purchase
