How It Compares

WP Multitool vs Query Monitor Both diagnose. WP Multitool also fixes. Query Monitor is great for debugging one request at a time. WP Multitool logs the slow queries over time, suggests indexes with EXPLAIN, and fixes them in a click. See full comparison →

WP Multitool vs WP Rocket WP Rocket does the frontend. WP Multitool does the backend. WP Rocket makes pages load faster. WP Multitool finds why the backend was slow to begin with. See full comparison →

WP Multitool vs Perfmatters Perfmatters trims what loads. WP Multitool fixes why. Perfmatters strips scripts and assets off the front end. WP Multitool goes after the slow queries and bloat behind them. Fine to run both. See full comparison →

WP Multitool vs New Relic Enterprise SaaS vs a WordPress plugin. New Relic is a subscription service built for big infrastructure. WP Multitool runs on shared hosting, fixes what it finds, and costs a flat price. See full comparison →

WP Multitool vs WP-Optimize Database cleanup vs the whole backend. WP-Optimize focuses on cleaning the database. WP Multitool does that too, plus slow queries, autoload, config, and the rest of the backend. See full comparison →

WP Multitool vs LiteSpeed Cache LiteSpeed speeds delivery. WP Multitool fixes the backend. LiteSpeed Cache is a full free delivery suite. WP Multitool handles the backend it doesn't touch, like autoload and slow queries. Run both. See full comparison →

WP Multitool vs NitroPack A monthly cloud bill vs a flat-price fix. NitroPack rents you speed from its cloud every month and never touches why the backend is slow. WP Multitool finds the root cause on your own server and fixes it, for a flat price. See full comparison →

WP Multitool vs All 16 tools 16 optimization tools, honestly mapped. The full honest map - caching, assets, DB cleanup, and diagnostics, all compared. See all comparisons →

WP Multitool focuses on the performance issues that frontend caching plugins don't touch.

Fixing a Specific WordPress Problem?

Start with the diagnosis, not the plugin. These guides walk the exact bottleneck end to end.

I don't know where to start Run one whole-site scan and get a worst-first list - each finding linked to the module that fixes it → wp-admin is slow but the frontend is fast Diagnose a slow WordPress admin dashboard - admin-ajax, Heartbeat, autoload, and slow hook callbacks → A query is dragging every page Find and fix slow WordPress database queries with EXPLAIN - no guessing which plugin → wp_options is bloated Reduce autoloaded data bloat in wp_options safely - the query that runs on every request → My site is down - critical error A logged-in admin goes straight to WordPress Recovery Mode when a plugin or theme crashes - no waiting for the email → Installed a caching plugin, still slow Find what the page cache cannot touch - slow queries, autoload, callbacks, phone-home → Which plugin is slowing my site down? Screen the list against ~53,700 clean-install benchmarks, then profile the real request for the exact callback → debug.log is eating my disk Group the repeats, rotate it with a backup, and see which plugin is spamming it →

Install the plugin, run Site Doctor, and apply the fixes it lists. The scan runs on your own server.

No plugin installed yet? Start with the free outside check - TTFB, compression, page size, and WordPress detect from outside.

Built by

Marcin Dudek

I built WP Multitool because I got tired of installing 5-6 different plugins and spending hours on looking and configs just to optimize basic things. Now I just install WP Multitool and optimize the backend within minutes.

FAQ

Common questions, straight answers.

Will this break my site?

Auto-backup before every destructive change. One-click restore if something goes wrong. Plus, the fatal error handler catches crashes and lets you recover instantly. You'd have to try pretty hard to break something permanently.

Do I need to disable my cache plugin?

No. Multitool complements cache plugins - it fixes root causes while they hide symptoms. Use both. WP Rocket handles the frontend, Multitool handles the backend.

What WP/PHP versions are supported?

WordPress 5.3 through 7.1+, PHP 7.4+, MySQL 5.7+ / MariaDB 10.2+. Fully tested on WordPress 7.1.3. But if you're not on PHP 8.2+ yet, the System Info module will roast you about it.

Is there support?

You email me directly and I read it - no ticketing system, just real answers from the person who built the plugin. Found a bug or have feedback? I actually want to hear it. Want the full toolkit? See the plans →

Can I use it on multiple sites?

Yes. The Pro Annual ($199/yr) and Pro Lifetime ($499) plans both cover unlimited sites - one license for your whole portfolio. Running just one site? Pro is $79/yr for a single site - the cheapest way to get all 19 modules.

What if it doesn't help my site?

14-day money-back guarantee on every plan. If it doesn't solve your problem, you get your money back.

Why did the price change from $50 to $499?

The early access price of $50 was intentionally low to get real users and real feedback. After ~40 customers and consistent feedback that it was underpriced, the price now reflects the tool's actual value. Today there are three tiers: Pro $79/year (1 site), Pro Annual $199/year, and Pro Lifetime $499.

Which LLM is the code sent to? Is there control over what data leaves my server?

Diagnostics never leave your server. The Slow Query Analyzer runs entirely locally - it uses MySQL EXPLAIN and rule-based pattern matching to analyze queries, not an external LLM. Your wp-config.php, credentials, and all other data stay on your server. The only outbound calls are the license and update check on paid plans, which carries two anonymous counters you can switch off.
