Debug Bar

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

Share of active installs on each version of this plugin · 89% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price.

Older reviews call it a lifesaver, but the recent ones report PHP errors, WordPress 6.7 incompatibility, and a plugin that's gone over a year without an update.

   Debug Bar is still listed in WordPress’s own developer documentation as a go-to debugging tool, yet it hasn’t been updated in over a year and throws PHP errors. It’s a clear example of Automattic promoting a tool while failing to maintain it – a pattern that’s become too common. For a plugin they recommend, its neglect is frustrating and undermines developer trust.

   This is a very useful plugin, but I am getting errors when WP_DEBUG is set to true based on the updates in WordPress 6.7. Notice: Function _load_textdomain_just_in_time was called <strong>incorrectly</strong>. I hope there will be an update soon!

   A plugin without which I cannot imagine my work. It would definitely be much more difficult.

   Where is the debug? Only memory usage is displayed… Where are the usage instructions?
