mod_pagespeed 1.15 · Apache

Apache PageSpeed module

The Apache PageSpeed module — mod_pagespeed — maintained again. mod_pagespeed 1.15 is the commercially supported continuation of Google's open-source mod_pagespeed: the same ModPagespeed directives and the same filters, rebuilt against current dependencies with ongoing security patches. It loads as a native Apache module — not a proxy, not a sidecar.

What it is

Google released its final open-source mod_pagespeed in 2020; the Apache Incubator podling that hosted it has since retired. mod_pagespeed 1.15 picks up that lineage. It is a drop-in replacement for the open-source Apache module — your existing pagespeed.conf and ModPagespeed directives continue to work — with the parts that had gone stale brought current.

• Current dependencies. Rebuilt with Bazel against up-to-date libraries, so the module builds and runs on current Apache and current Linux distributions.
• Security patches. Known CVEs from the open-source project are patched, and security maintenance is ongoing.
• The classic filter set. WebP transcoding and JPEG/PNG/GIF optimization, plus combine_css, combine_javascript, image spriting, in-place resource optimization, and domain mapping.
• Same directives. The ModPagespeed* directive set is unchanged from 1.13.35.2 — see the full directive index.

Install

The Apache module is a drop-in replacement for the open-source mod_pagespeed Apache module — the same ModPagespeed directives, with current dependencies and patched CVEs. It installs from the signed apt/yum repository at packages.modpagespeed.com. One command configures the apt or yum source and imports the signing key:

curl -fsSL https://packages.modpagespeed.com/install.sh | sudo sh

Then install the package and restart Apache:

sudo apt install mod-pagespeed     # Ubuntu 24.04
sudo dnf install mod-pagespeed     # AlmaLinux / RHEL 9
sudo systemctl restart apache2     # or: systemctl restart httpd

Every artifact is GPG-signed and listed in SHA256SUMS. For other distributions or air-gapped hosts, the downloads page lists the direct .deb / .rpm packages; see the getting-started guide for verification and the full directive setup.

A minimal Apache config

The distribution package loads the module automatically on install. Enable it and point it at a cache directory in pagespeed.conf (or your virtual host configuration):

ModPagespeed on
ModPagespeedFileCachePath /var/cache/pagespeed

That is enough to start optimizing with the default CoreFilters set. To add or scope individual filters — for example, per virtual host:

<VirtualHost *:80>
    ServerName www.example.com
    ModPagespeed on
    ModPagespeedFileCachePath /var/cache/pagespeed
    ModPagespeedEnableFilters rewrite_images
</VirtualHost>

Verify the module is rewriting responses by checking for its header on a request:

curl -I http://localhost/

On Apache the response carries X-Mod-Pagespeed. The first request to any URL shows X-Mod-Pagespeed: MISS while resources are optimized; subsequent requests show HIT.

This is the minimal setup. For the complete directive set — filter selection, per-directory and per-virtual-host scoping, caching, HTTPS, and domain configuration — see the mod_pagespeed 1.15 documentation.

Activate a license

Install and run the module — it loads into Apache and fully optimizes your site right away. Unlicensed installs keep optimizing and add an X-PageSpeed-Warn: unlicensed header (plus an admin-console notice and a startup-log warning). A commercial license is required for production use. Open the admin console at /pagespeed_global_admin on your server to activate a license you already own.

Pricing

Same as every other mod_pagespeed 1.15 install path: $49/server/month, or $39/server/month billed annually ($588/server/year). One license per Apache instance. No per-request fees.

A commercial license is required for production use. Subscriptions are billed immediately on purchase via FastSpring — manage your subscription from /pagespeed_global_admin.
