The short answer
This is not a fair fight, and I will not pretend it is. WP-Sweep is a small, free, single-purpose cleaner that does one job safely. WP Multitool contains that job as one of its 18 modules and then adds an entire diagnostic layer on top, which is why people search for a WP-Sweep alternative in the first place. If a twice-a-year sweep is all you need, keep WP-Sweep and your $9. If you need to know why the site is slow, a sweeper cannot answer that question.
Looking for a WP-Sweep alternative?
Be clear about why first. If you just want more cleanup power, Advanced Database Cleaner goes far deeper (orphaned tables, retention rules) and WP-Optimize bundles cleanup with caching and images. If the real reason is that sweeping did not make the site faster, the missing piece is diagnosis, and that is WP Multitool's job: EXPLAIN on slow queries, autoload analysis, per-plugin scoring. I mapped the whole field in WP Multitool vs the alternatives.
What WP-Sweep does
WP-Sweep, by Lester Chan (a name WordPress old-timers will recognize), sweeps the usual accumulated junk from your database: revisions, auto-drafts, deleted and spam comments, orphaned and duplicated metadata, unused terms, transients and oEmbed caches, plus table optimization. One screen, per-item counts, a confirmation, done.
Its standout design decision is safety. Instead of running raw SQL deletes, it uses proper WordPress deletion functions like wp_delete_post() and delete_post_meta() wherever possible, so hooks fire and caches stay consistent. That is a genuinely good engineering choice that plenty of direct-SQL cleaners skip. It is free, has no premium version, no upsells, and it is still maintained. Around 100,000 sites run it, and for what it does, it deserves the trust.
What it does not have: scheduling, diagnostics of any kind, or anything beyond that one screen.
What WP Multitool does
WP Multitool's Database Optimizer covers the same sweep territory: revisions, auto-drafts, trash, expired transients, orphaned meta, spam comments and OPTIMIZE TABLE, with a preview of reclaimable space before deleting and scheduled cleanups so hygiene happens without you remembering to log in.
That module is roughly one eighteenth of the plugin. The rest answers the question a sweeper never asks: why is this site slow? The Slow Query Analyzer logs slow queries and runs MySQL EXPLAIN locally, rule-based, with ready-to-run index suggestions. The Plugin Performance Score puts a 0 to 100 benchmark next to every plugin on your Plugins page. The Autoloader Optimizer classifies and fixes autoloaded option bloat with backup. Add the callback profiler, Site Doctor's misconfiguration scan, Debug Log Guard, a safe wp-config editor, and a WP-CLI surface.

Where WP-Sweep wins
It is free, forever, with no upsell. It is tiny, so there is nothing to configure and almost nothing to break. Its use of core deletion APIs is a real methodological plus for safety, and it sweeps a couple of things (duplicated meta, unused terms) that WPMT's cleanup module does not explicitly list. For a small blog that just wants an occasional tidy-up, WP-Sweep is the honest recommendation and adding anything heavier would be overkill. I mean that.
Where WP Multitool wins
Everywhere outside the sweep. A clean database is not the same thing as a fast site: if a query is scanning a million postmeta rows, or one plugin is eating your memory, or your autoload is several megabytes, sweeping revisions changes nothing. WP-Sweep has no way to even detect those problems. WPMT logs the slow query, EXPLAINs it, and suggests the index. It also schedules cleanups, previews reclaimable space, and gives you 17 other modules. When caching and cleanup both fail to fix a slow site, a sweeper has nothing left to say, and that is the exact gap WPMT fills.
Which should you use?
- Small site, occasional cleanup, zero budget: WP-Sweep. Genuinely fine.
- Site is slow and you do not know why: WP Multitool. The problem you have is diagnostic, not janitorial.
- Already happy with WP-Sweep as your broom? You can keep it and still run WPMT for the diagnostics; just do not run two cleanup schedules over the same data. In practice WPMT's cleanup module makes the sweeper redundant.
The bottom line
WP-Sweep is a good free broom and I have no interest in trashing it. WP Multitool is a diagnostic toolkit that happens to include a broom. If the question on your mind is "why is this site slow", the broom was never going to answer it. Pricing: $9 Lite (one-time, unlimited sites, 11 modules) → $79/yr Pro (1 site) or $199/yr (unlimited sites) with all 18 modules → $499 lifetime (unlimited sites). Details on pricing, and the full landscape is in WP Multitool vs the alternatives.
FAQ
Is WP Multitool a WP-Sweep alternative? For the cleanup job, yes: WP Multitool's Database Optimizer covers the same sweep territory (revisions, drafts, spam, transients, orphaned meta, OPTIMIZE) and adds scheduled cleanups plus a reclaimable-space preview. But WP-Sweep is free and sweeps a couple of things WP Multitool's cleanup module does not explicitly list, like duplicated meta and unused terms. If an occasional free sweep is all you need, WP-Sweep is genuinely fine. WP Multitool is for when you also need to know why the site is slow.
Is WP-Sweep safe to use? Its design leans safe: instead of raw SQL deletes it uses WordPress core deletion functions like wp_delete_post() and delete_post_meta() wherever possible, so hooks fire and caches stay consistent. As with any cleanup tool, take a database backup before a big first sweep, because deletions are permanent.
Can WP-Sweep and WP Multitool run together? Yes, they coexist fine. Just do not run two cleanup routines over the same data; pick one tool to own the cleanup. In practice WP Multitool's cleanup module makes the sweeper redundant, and it adds the diagnostic layer WP-Sweep never had. WP Multitool Lite is $9 one-time for unlimited sites.
