PluginPedia reports published data and observable changes. It does not rate plugin quality or safety, infer intent, or make recommendations. These are observations rather than a verdict. How this works
Ownership
Held by Danny van Kooten throughout, with no change of ownership observed since daily tracking began on 02 Aug 2026.
Full observed history, including every field transition
Committing accounts
Read from the plugin’s public release log, so these predate this registry. A committing account is not an owner. Thirty accounts commit to WooCommerce and it has never changed hands.

This registry did not observe a transfer; it read these names off a public log. Whether that reflects a change of ownership is not something the directory publishes.
Adoption
How widely the plugin is installed, and what the people running it think of it. WordPress.org rounds install figures to one significant digit, so they describe an order of magnitude rather than a headcount.
Very widely adopted: 1,000,000+ active installs. In the top tier of the directory by install count.
7,661 downloads a day over the last 7 days, falling 26% against the 7 days before. Downloads are counted exactly and without a ceiling, so they show movement the rounded install figure cannot.

Daily record
Every field we record, one column per observation. Fields that never moved are named once rather than repeated across every column. A row of identical numbers would be padding.

Is anyone still maintaining this?
- Last released 20 Aug 2026, 19 days ago.
- Declares compatibility with WordPress 7.1, which is current.
- 1 of 1 support threads answered in the last two months.
- The same account maintains 8 other plugins, 8 of which were updated in the last 90 days. the account is active.
A plugin that does one thing correctly may need no changes for years; a long gap is not, by itself, evidence of neglect.
History
Everything dated that this registry holds about the plugin, most recent first. Releases carry the author’s own release date; everything else is dated to when it was observed.
Entries marked from the release log predate this registry, and daily observation began 02 Aug 2026. They were read from the plugin’s public SVN history after the fact, not watched as they happened. Everything else was observed directly.

Every record on this site, this one included, works under the same limits. We read what WordPress.org publishes about a plugin, never the plugin’s own code, so nothing here says whether a plugin is well built or safe. Install counts reach us already rounded; a change smaller than a band step doesn’t show. We don’t track security advisories yet. For anything older than our first observation we rely on the plugin’s public release log, where one exists. What this registry can and cannot see
Similar plugins
Plugins that share this one’s tags and talk about the same things in their own descriptions. Distinctive tags count for far more than broad ones. Sharing hover means something, sharing woocommerce does not, and a plugin that never mentions the subject matter is left out however its author tagged it. Among close matches, more widely installed plugins are listed first. This is a grouping rather than a ranking of quality.
