Documented presentation. No practical test, speed gain, commercial result or compatibility level was measured for this listing.

A free version or tier is available; paid features and connected services may cost extra.

What it does

Optimise HTML, CSS, and JavaScript, with options for lazy loading and font optimisation.

Who it may suit

A site that wants to optimise its HTML, CSS, and JavaScript resources after identifying a loading problem.

When to consider another approach

The free version does not replace a page cache; aggregating or delaying scripts without checking can break a form or menu.

Limits and paid features

Page caching is not the role of the free core; Pro adds features including page caching and automatic critical CSS.

Check before deciding

Enable one option at a time, compare the same page before and after, and test interactions, consent, and payment while logged out of the administrator account.

  • Check supported versions and maintenance on the official page.
  • Test interactions with your theme and plugins on a copy of your site.
  • For paid plans, check renewals, site limits and refund conditions.
