Best WordPress Database Optimization Plugins: Four Compared and Scored
best-of list, checked 12 Nov 2026Hello my friend. A WordPress database collects old revisions, auto drafts, spam and expired leftovers, and a cleanup plugin removes them. This page scores four options out of 20: Advanced Database Cleaner, WP-Sweep, WP-Optimize and LiteSpeed Cache. Everything comes from the plugin listings read on 12 Nov 2026, with no speed test. One habit matters more than the plugin you pick: take a backup first, because every cleanup is permanent.
// disclosure: I sell SEO services. No vendor pays for a place on this list. Scores are my editorial opinion, based on published information. I did not run hands-on tests for this page.
- four plugins, one page
- read from plugin listings, dated
- backup before any cleanup
// scores are my editorial opinion from published information, not hands-on tests. Prices checked 12 Nov 2026. All 4 are scored below.
Match the Plugin to Your Cleanup Job
A cleanup cannot be undone. Pick the tab that sounds like your site, then take a backup.
Advanced Database Cleaner lists a preview with the space each cleanup would free, and a keep-last-X-days rule, in its free version.
WP-Optimize lists scheduled clean-ups from daily to monthly in its free version. Advanced Database Cleaner offers up to 5 scheduled tasks free.
Its listing names a Database Cleaner and Optimizer but does not say what it removes. Read the settings screen before you run it.
// my own working rule of thumb. Features change, so check each plugin listing.
The Best Database Plugins in Three Picks
If you want to see what a cleanup will remove, Advanced Database Cleaner. If you want a lean tool that respects hooks, WP-Sweep. If you want one plugin for cleanup plus caching, WP-Optimize. Back up first with any of them.
Advanced Database Cleaner
The free version cleans revisions, drafts, unused meta, expired transients and oEmbed caches, with a preview and a keep-last-X-days rule. Orphan detection is Premium.
WP-Sweep
Uses WordPress delete functions so other plugins’ hooks still fire, and has WP-CLI commands. It lists no scheduled tasks, and needs WordPress 6.8 and PHP 8.2.
WP-Optimize
Cleans tables, revisions, drafts, trash and spam, with scheduled clean-ups free. It also does caching and image compression, which you may not want.
// prices are vendor-stated, checked 12 Nov 2026. The order is my opinion, not a lab result.
Notice what the short answer does not say. It does not say “clean your database to rank higher.” On a small site the gain is often tiny, and caching and hosting usually matter more. For the backup step, see my guide to the best WordPress backup plugins. For the wider speed picture, read how to speed up a WordPress site. If you would sooner hand it over, that is what my cheap SEO services are for.
All Four Plugins, Ranked by Score
Here are the four plugins in order, scored out of 20. The score adds up four criteria that matter to a small site, and the next section explains each one.
// editorial opinion based on published information, checked 12 Nov 2026. Not hands-on test results. Ties are ordered by how much the listing says it removes.
A low place is not an insult. LiteSpeed Cache scores lowest because its listing gives no detail on what the cleaner removes, and it is mainly a caching plugin. If you already run it, the cleaner may be all you need, once you have read its settings screen.
How I Scored These Plugins
Each plugin gets 1 to 5 points on four criteria, for a maximum of 20. The scores are my editorial opinion, formed from each plugin’s published listing. They are not the result of hands-on testing.
Value on a Small Budget
What does it cost? A free version that does real work scores 5. A paid tier you need for basics scores lower, and a price I could not read is not counted.
What It Cleans
How much does the listing say it removes? Revisions, drafts, spam, meta, transients and orphaned data score higher, and a vague listing scores low.
Control and Safety
Does it preview, keep recent items, protect keys, or schedule? Control scores higher, because a cleanup cannot be undone.
Try Before You Pay
A permanent free version scores 5. A paid-only plugin scores 1 or 2.
// one rule sits above the scores: a price or feature I could not read on the plugin listing is marked “not shown”, and I do not quote one from memory.
Why these four? Because they are the cleanup tools people ask me about. All four have a free version, so price barely separates them. Safety does, which is why control carries as much weight as coverage.
The Top Two Database Plugins Reviewed
These two score highest for a small site. Each card says what the plugin does, who it fits, when to skip it, the vendor-stated price, and one flag.
Advanced Database Cleaner
Advanced Database Cleaner, version 4.2.0 when I read it, has 100,000+ active installations and needs WordPress 5.0 and PHP 7.0 or higher. The free version cleans old revisions, auto drafts, trashed posts, pending, spam and trashed comments, pingbacks and trackbacks, unused meta, unused relationships, expired transients and oEmbed caches, plus duplicated meta.
It previews items and shows the space each cleanup would free, supports a keep-last-X-days rule, and manages tables, options, transients, post meta, user meta and cron jobs, with optimize and repair tools for tables. Scheduled cleanups are limited to 5 automation tasks, running once, hourly, twice daily, daily, weekly or monthly. WooCommerce tools cover orphaned product variations and expired customer sessions.
Premium adds orphan detection for options, tables, meta, transients and cron jobs, a remote SmartScan that identifies the owners of items, unlimited automation tasks, Action Scheduler cleanup, database analytics and full multisite filtering. The FAQ calls a database backup before cleanup required, not optional.
Who it fits: a site that wants to see what will go before it deletes anything. Skip it if: you need orphaned options and tables cleaned on the free plan. That is Premium.
Price: free, with up to 5 scheduled tasks. A Premium version exists, and its price was not on the listing I read.
One flag: the listing says cron jobs should be removed only if you know which are safe, and it is not yet compatible with SharDB, HyperDB or Multi-DB.
WP-Sweep
WP-Sweep cleans post revisions, auto drafts and deleted posts, unapproved, spam and deleted comments, orphaned meta for posts, comments, users and terms, orphaned term relationships, unused terms, duplicated meta, expired transients and oEmbed caches. It also optimizes database tables.
It uses WordPress delete functions such as wp_delete_post, so hooks that other plugins rely on still fire. As of version 2.0.0, optimization is scoped to the current install’s table prefix. WP-CLI works, for example wp sweep revisions for one sweep or wp sweep all for every sweep.
The listing says every sweep is irreversible and tells you to back up first. It warns that several plugins store data where WP-Sweep reads it as orphaned, including Polylang, WPML and Elementor Popup Builder, so protect their meta keys with the whitelist filters. It needs WordPress 6.8 and PHP 8.2 or higher.
Who it fits: a developer or careful owner who wants a lean tool and WP-CLI. Skip it if: you want a calendar of scheduled cleanups, or you run an older WordPress or PHP. The listing mentions no scheduling.
Price: free. The listing mentions no paid version.
One flag: the high requirements, WordPress 6.8 and PHP 8.2, will block older sites. Uninstalling leaves nothing behind, which is tidy, but the cleanups stay irreversible.
// every number in these cards comes from the vendor page or official documentation, read on 12 Nov 2026. The “who it fits” lines are my opinion.
Two More Options Worth Knowing
These two fit narrower cases: an all-in-one plugin, and a caching plugin with a cleaner.
WP-Optimize
WP-Optimize has more than 1 million active installations. Its listing says it cleans tables, post revisions, auto drafts, trashed posts, spam and trashed comments. Scheduled clean-ups, daily, weekly, fortnightly or monthly, and keeping a set number of weeks of data are free. It requires WordPress 4.9 and PHP 7.2 or higher.
It is more than a cleaner. The free version also lists page caching, image compression with WebP conversion, and minification of HTML, CSS and JavaScript. That is useful if you want one plugin, and unhelpful if you already run a caching plugin, because the page says it cannot run alongside another page-caching plugin.
Premium adds multisite database optimization, selective table optimization, specific-time and one-off scheduling, an optimization preview, WP-CLI support, lazy loading and WooCommerce tweaks. The listing strongly recommends a full backup before first use and before major upgrades, and says the plugin cannot restore a database without a backup.
Who it fits: a site with no caching plugin that wants cleanup, caching and image compression together. Skip it if: you already run a caching plugin. Use a dedicated cleaner instead.
Price: free. Premium exists, and its price was not on the listing I read.
One flag: some shared hosts block the OPTIMIZE command, which limits savings, and InnoDB tables disable some features.
LiteSpeed Cache
LiteSpeed Cache is mainly a caching plugin with 7+ million active installations. Its listing names a Database Cleaner and Optimizer under General Features, and gives no detail on what it removes. The page says it will always be free and open source.
The 7.9.2 changelog says the database optimizer keeps recent auto drafts, limits cleanup scope, reports cleanup failures, limits multisite management to network administrators, and scopes table operations to the site’s table prefix.
The listing does not mention scheduling or backup warnings for the cleaner. The FAQ says these general optimization features do not require a LiteSpeed web server. The caching features do, or QUIC.cloud for sites on other servers. Database optimization is not listed among the paid QUIC.cloud services.
Who it fits: a site already running LiteSpeed Cache that wants basic cleanup without another plugin. Skip it if: you want a clear list of what the cleaner removes before you run it. The listing does not give one.
Price: free. The page says the plugin will always be free and open source.
One flag: I could not read what the cleaner removes, so read its settings screen and take a backup before you run it.
// every number in these cards comes from the vendor page or official documentation, read on 12 Nov 2026. The “who it fits” lines are my opinion.
Database Plugins Compared: Cleanups, Control and Requirements
This table puts the four plugins side by side. “Not stated” means the listing I read did not say. It does not mean the feature is missing.
| Advanced Database Cleaner | WP-Sweep | WP-Optimize | LiteSpeed Cache | |
|---|---|---|---|---|
| Cleans revisions and drafts | yes | yes | yes | not stated |
| Scheduled cleanups | yes, up to 5 free | not mentioned | free, daily to monthly | not mentioned |
| Preview before delete | yes, free | not stated | Premium | not stated |
| Orphaned data | Premium | orphaned meta, free | not stated | not stated |
| WP-CLI | not stated | yes | Premium | not stated |
| Requirements | WP 5.0, PHP 7.0 | WP 6.8, PHP 8.2 | WP 4.9, PHP 7.2 | not stated |
| Best for (my opinion) | seeing before deleting | lean, careful owners | one plugin for everything | LiteSpeed users |
// all details from the WordPress.org listings, checked 12 Nov 2026. The last row is opinion.
Read the table by row. Row three is the safety row, and only Advanced Database Cleaner lists a free preview. Row six matters for old sites, because WP-Sweep needs WordPress 6.8 and PHP 8.2 or higher.
What These Plugins Cost, Free, With Premium Extras
All four have a free version that does real work. Premium prices were not on the listings I read, so I quote none.
// checked 12 Nov 2026 from the WordPress.org listings. Premium prices for WP-Optimize and Advanced Database Cleaner were not on those pages, so no figure is quoted.
Look at the shape. There is no price to compare, so choose on safety and on what you already run. The real cost of a cleanup is the time to take and test a backup, and the risk of skipping it.
You Can Start Free: A Zero-Dollar Cleanup Routine
Yes, you can clean your database for free, and you can also stop most of the buildup with one line in wp-config.php.
Back Up
files and database
Test the Restore
once
Run a Preview
if the plugin has one
Clean One Type
revisions first
Check the Site
front page, a post, admin
Limit the Buildup
WP_POST_REVISIONS
// the facts named here are from the WordPress.org listings and the WordPress developer wp-config page, checked 12 Nov 2026: revision limit syntax and default.
Step by Step, in About an Hour
First, take a full backup, files and database, and keep a copy off the server. Then restore it once on a test site or a staging copy, so you know it works. WP-Optimize says it cannot restore a database without an existing backup.
Next, run the cleanup one type at a time, starting with post revisions. Use a preview if your plugin has one. With Advanced Database Cleaner, that shows the space each cleanup would free. Open the front page, a post and the admin after each step.
Then limit future buildup. The WordPress developer page shows that define( ‘WP_POST_REVISIONS’, 3 ); in wp-config.php keeps at most 3 revisions per post, and false turns revisions off. If you do not define it, revisions are enabled. Some users reported it only worked on the first line below the opening comment block.
Finally, run a cleanup once a month, not every day. For example, a blog with 200 posts and unlimited revisions may have thousands of old versions, and one monthly pass keeps that tidy.
Six Duels Between Database Plugins
Most people are stuck between two names, not four. Here are the pairs I get asked about, each with a direct verdict. The verdicts are opinion, and the details were checked on 12 Nov 2026.
Advanced Database Cleaner or WP-Optimize
Advanced Database Cleaner lists a free preview and a keep-last-X-days rule. WP-Optimize lists free scheduled clean-ups and extras like caching. If you want to see before deleting, ADC. If you want one plugin for several jobs, WP-Optimize.
WP-Sweep or Advanced Database Cleaner
WP-Sweep is lean, uses WordPress delete functions and has WP-CLI. ADC has a preview and scheduling. For a developer, WP-Sweep. For a site owner who wants to look first, ADC.
WP-Optimize or LiteSpeed Cache
WP-Optimize says it cannot run beside another page-caching plugin. If you already run LiteSpeed Cache for caching, use its cleaner or a dedicated cleaner rather than adding WP-Optimize caching.
A Plugin or wp-config.php
A revision limit in wp-config.php stops revisions from piling up, and a plugin cleans what is already there. The two work together, and the limit costs nothing.
Free or Premium
The free versions cover revisions, drafts, spam and transients. Premium mostly adds orphan detection, selective tables and extra scheduling. Most small sites do not need it.
Cleanup or Better Hosting
On a small site, a cleanup often gives a tiny gain. Caching and hosting usually matter more, so look at those first.

How to Choose a Database Plugin for Your Site
Pick the job first and the brand last. Follow these five steps in order.
Step 1: Check What You Run
If you already have a caching plugin with a cleaner, you may need nothing new.
Step 2: Name the Job
“See what will go,” or “a monthly schedule,” or “a one-time clean.”
Step 3: Match the Job to a Plugin
Preview points to Advanced Database Cleaner. Scheduling points to WP-Optimize or ADC. Lean and CLI points to WP-Sweep.
Step 4: Check Requirements
WP-Sweep needs WordPress 6.8 and PHP 8.2. Others accept older versions.
Step 5: Back Up, Then Run
One type at a time, with a restore you have tested.
Three Ready-Made Combinations
wp-config Limit Plus One Cleanup
Set WP_POST_REVISIONS, then run one careful cleanup with a free plugin.
Free Scheduled Cleanups
WP-Optimize or Advanced Database Cleaner free, running monthly after a tested backup.
WP-Sweep With WP-CLI
Run wp sweep revisions from the command line on a staging copy first.
// prices vendor-stated, checked 12 Nov 2026. The combinations are my suggestion, not a rule.
Six Common Mistakes With Database Cleanups
The usual mistake is skipping the backup. Here are six I see often, each with the fix.
Cleaning With No Backup
Every sweep is irreversible, per the WP-Sweep listing. Fix: take and test a backup first.
Deleting Everything at Once
You cannot tell what caused a problem. Fix: clean one type at a time and check the site.
Expecting a Speed Miracle
On a small site the gain is often tiny. Fix: look at caching and hosting first.
Leaving Revisions Unlimited
They pile up again. Fix: set WP_POST_REVISIONS in wp-config.php.
Removing Cron Jobs You Do Not Know
ADC says remove them only if you know they are safe. Fix: leave them alone if unsure.
Ignoring Plugin Data Marked Orphaned
WP-Sweep warns that Polylang, WPML and Elementor Popup Builder data can look orphaned. Fix: protect their keys with the whitelist filters.
// these are my observations from client work, not survey data.
One more thing, said gently. A clean database is housekeeping, not a ranking tactic. If you want an expert to look at speed and the database together, see my technical SEO page, and my guide to time to first byte.
Limits of This Database Plugin Comparison
This comparison is built from published plugin listings, read on one day. It is not a hands-on test, and several things can change after the date at the bottom.
Gaps in the Evidence
- LiteSpeed Cache: the listing does not say what the database cleaner removes
- WP-Optimize and Advanced Database Cleaner: Premium prices were not on the listings I read
- WP-Sweep: the listing mentions no scheduling and no paid version
- No speed measurements were taken, so I make no claim about how much any cleanup helps
How to Use It Safely
- Treat the scores as one person’s opinion, formed from published information
- Read the live plugin listing before you install
- Take and test a backup before every cleanup
- Run on a staging copy first if you can
// speed gains, table sizes and cleanup safety on your own site were not measured. I make no claim about them.
Database Optimization Plugins: Questions and Answers
Short answers to what WordPress owners ask before they clean their database.
Will database optimization make my site faster?
Sometimes, on a site with a lot of old data. On a small site the gain is often tiny. I measured nothing here, so I make no speed claim. Caching and hosting usually matter more.
Is it safe to delete post revisions?
Usually, but take a full backup first, because you lose the older versions of your posts. You can limit future revisions with WP_POST_REVISIONS in wp-config.php.
How do I limit revisions in WordPress?
The WordPress developer page shows define( ‘WP_POST_REVISIONS’, 3 ); to keep at most 3 per post, and false to turn revisions off. If it is not defined, revisions are enabled.
Do I need a plugin for this?
Not always. A limit in wp-config.php stops revisions piling up, and a plugin cleans what is already there.
Which plugin shows a preview before deleting?
Advanced Database Cleaner lists a preview with the space each cleanup would free in its free version. WP-Optimize lists an optimization preview as a Premium feature.
Can a cleanup break my site?
It can, if it removes data a plugin still needs. WP-Sweep warns that some plugins store data it reads as orphaned. Back up first and check the site after each step.
How often should I clean the database?
Monthly is plenty for most sites. WP-Optimize says its free version can schedule clean-ups from daily to monthly.
Does LiteSpeed Cache clean the database?
Its listing names a Database Cleaner and Optimizer, but does not say what it removes. The FAQ says these features do not need a LiteSpeed web server.
