- Long abandoned. No update in 6+ years — the top precursor to removal once a vulnerability is found.
- Falling behind WordPress. Tested up to WordPress 5.5.20.

Update activity
How busy the existing users are, measured as downloads in the last 30 days for every 1,000 active sites. A spike means a new release everyone's pulling; a long, slow decline means an aging user base that updates less.
Release cadence
No release in a yearHow often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Estimated value
What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.
Est. annual revenue
Est. acquisition value
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. A small install base leaves thin data to model from.

Works great, even with picture tags! The fade-in effect of the lazyloaded images is really nice! And the developer is really active and helped me a lot! Thanks again, Patrick 🙂 This topic was modified 7 years, 2 months ago by dutze.

As a developer I knew the lib js that does a very good job. So I’m not surprised to have a plugin that does a good job too. (Except, video loading does not work) This topic was modified 7 years, 7 months ago by stephanetessieralu.

I already tested some other plugins against this plugin for my site load speed and request counts. This plugin is greatly reducing my page load speed I really don’t know why they couldn’t beat this plugins performance on gtmetrix. Performance is really high as author mentioned!

LazySizes is lazyloading done right. I’ve used it before and was pleased to see that it’s now available as a WordPress plugin. For me, this is the best lazy-load script on the planet. I’ve tried many WordPress plugins and all failed except LazySlides. Excellent!
