The Windows installer registers the module in IIS as a native HTTP module, creates the default cache directory at %ProgramData%\We-Amp\IISWebSpeed\Cache, and installs a server-level pagespeed.config.

nginx

The signed apt repository at packages.modpagespeed.com ships the nginx dynamic module (nginx-module-pagespeed) prebuilt for Debian and Ubuntu, amd64 and arm64. Each .so is built against — and pinned to — that distribution’s exact stock nginx version. Configure the repository and install with one command:

curl -fsSL https://packages.modpagespeed.com/install.sh | sudo sh
sudo apt-get install nginx-module-pagespeed

Installing the package drops a modules-enabled auto-include snippet — there is nothing to copy by hand. The module is available for these distributions (amd64 + arm64):

Distribution	Stock nginx (pinned)
Debian 11 (bullseye)	1.18.0
Debian 12 (bookworm)	1.22.1
Debian 13 (trixie)	1.26.3
Ubuntu 22.04 (jammy)	1.18.0
Ubuntu 24.04 (noble)	1.24.0

The module is pinned to each distro’s exact stock nginx version (nginx’s --with-compat does not relax that check), so upgrading nginx past the stock version requires a matching rebuild. Run an nginx version we don’t yet package? Contact us for a pinned build.

Apache

The same signed apt/yum repository ships the Apache module — a drop-in replacement for the open-source mod_pagespeed Apache module, with the same configuration directives plus Cyclone Cache and patched CVEs. After configuring the repository, install the mod-pagespeed package:

curl -fsSL https://packages.modpagespeed.com/install.sh | sudo sh
sudo apt install mod-pagespeed     # Ubuntu 24.04
sudo dnf install mod-pagespeed     # AlmaLinux / RHEL 9
sudo systemctl restart apache2     # or: systemctl restart httpd

Installing the package pulls in Apache if it is not already present, enables the module, and drops a default pagespeed.conf (in /etc/apache2/mods-available/ on Debian/Ubuntu, /etc/httpd/conf.d/ on RHEL). Edit that file to turn filters on, then restart Apache. See the Apache guide for configuration details.

Other targets

The Envoy HTTP filter is experimental. Contact us for setup guidance.

Available platforms

mod_pagespeed 1.15 supports four web servers:

• nginx — Dynamic module shipped as a prebuilt, signed apt package (nginx-module-pagespeed) for Debian 11/12/13 and Ubuntu 22.04/24.04 (amd64 + arm64), each pinned to that distro’s stock nginx. Loads alongside your existing nginx binary. Running an nginx version we don’t yet package? Contact us for a pinned build.
• Apache — Drop-in replacement for the open-source mod_pagespeed Apache module, shipped as a signed apt/yum package (mod-pagespeed) for Debian 11/12/13 and Ubuntu 22.04/24.04 (amd64 + arm64) and AlmaLinux/RHEL 9 (x86_64; arm64 via direct download). Same configuration directives, plus Cyclone Cache and patched CVEs.
• IIS — Native module for Windows Server 2019+ (IIS 10+). 64-bit only. Installed via the Windows installer package.
• Envoy — Experimental HTTP filter for Envoy proxy deployments.

Licensing

mod_pagespeed 1.15 is licensed per site, on the same ladder as ModPageSpeed 2.0. The Business tier is $99/site/month with unlimited servers per site (see current pricing).

• Evaluate by running it. Install and run unlicensed — the module fully optimizes and simply adds an X-PageSpeed-Warn: unlicensed header (plus an admin-console notice and a startup-log warning). Production use requires a commercial license — but the software never locks you out.
• Subscriptions are billed immediately on purchase through FastSpring.
• A license covers one site, not a server count. Business allows unlimited servers per site; Starter ($99/year or $12/month) covers one site, up to two servers.
• Enterprise (from $5,000/year) and Hoster tiers cover larger estates and hosting providers.
• If you are migrating from IISpeed, your existing license transfers at no cost.
