Database Cleaner and Optimizer (Built for 2022+)


Clean your database for real, whatever its size is, while focusing on what can make it faster. An user-friendly UI will help you to make everything perfect. If there are too many issues to delete, it will use asynchronous requests to avoid timeouts. You will more information here: Database Cleaner on Meow Apps.


There are others database cleaners on the market, but since I felt like there were rather incomplete and old, based on my experiences with modern UIs and ways of coding plugins, I had to create this new one. Here are the current features:

  • The Auto Clean Button. It will clean everything you set on Auto in Database Cleaner. That will make your life easier, once everything is set up.
  • Clean the Usual Items: Revisions, drafts, trash, useless metas, useless comments, useless users, transients, etc. If I missed something, let me know: I can add support for new items right away.
  • Clean your Post Types. List your post types, and help you getting rid of data in unimportant post types such as the ones used for temporary data such as logs. Those slow down your WordPress more than anything else!
  • Clean your Tables. Display all your tables, their sizes, and help you getting rid of the useless ones.
  • Clean your Options. Display all your options, their sizes, and help you getting rid of the useless ones. You can also set your options as being not autoloaded.
  • Clean your Cron Jobs. Display all your jobs, their schedules, and help you getting rid of the useless ones.

For Post Types, Tables, Options and Cron Jobs, Database Cleaner has its own references in order to tell you by which plugins or themes they are use. For full support of this, you will need the Pro Version.

IMPORTANT: Please prepare a backup of your database before using this plugin! Better be safe than sorry 🙂

Why this plugin?

There are other similar cleaners on the market. I used them, but I always felt they were imperfect, with old UI, somehow frozen in time. There were also missing Post Types support, but I could handle this manually. At the end of 2021, I had issues with my databases (which were too big) and all those plugins simply failed; this was the last straw: I started to develop a fresh and new database cleaner plugin, with a PHP 7 base, modern concepts, and build to actually speed-up WordPress. I am now resolved to make it work for everyone, adding all the features you absolutely need.

This powerful plugin helps remove extra CSS added by plugins and themes and is to be celebrated. Use with care and see how may uninstalled plugins and themes have left rubbish in your installation. When looking at information from current plugins and themes, be careful to only delete what you know you don't need. I had to reinstall wordfence after I used database cleaner as a setting changed and I couldn't change it back. Looking forward to database cleaner cleaning up old multisite sites.

This is a great plugin to remove table entries left behind by delete plugins. However, it will be good if the plugins assigned to table entries stuck. Sometimes I assign plugins to table entries, it will say it is not valid and tell me to change the plugin. But the plugin is correct so I don't know what's wrong. Edit: Changed my star rating to 5 stars from 4. Reason being the great support that was provided by Jordy and the free Pro license for an unintentional bug report. As Meow plugins are already very functional, high quality and light weight (I use the database cleaner and lightbox plugins), the support brings it to the top. Keep up the good work. Highly recommended plugin!

I began using it since my database was begining to slow down my site by taking too much processor time on the server on some queries, but because i'm no expert on database cleanup i wanted a tool to do the job for me if possible. Well this is the tool.

I would give this awesome little plugin 5 stars, its now a must use on all sites and works perfectly, but for the really annoying review me box.

`The plugin is easy to use and successfully cleans the selected tables or entries. Also you can see herewith which ancient cronjobs are still running unnecessarily in the background, although the plugins or similar do not even exist anymore. Simply great. The communication with the manufacturer is super easy and you get so fast an answer, especially if you use for example the "Used By" function and pass this on. The plugin also does not stop here but is always fed with new data. Keep up the good work. What I would wish here only at the great "Used by" function, would be even easier transfer via button, without filling out a form. The problem I have here, for example, are many entries that I have added manually, but too many entries are to transfer into the form.
