Free, read-only WordPress health check: find overlapping or duplicate plugins, bloat, and unused plugins & themes — in plain language.

See what a plugin may still support before you deactivate, replace, or remove it.

Move inactive plugins out of the plugins folder into an archive, then restore, download or permanently delete them later.

WordPress tells you which plugins are active. It never tells you which are used. PluginTidy works that out, and keeps working it out.
