Apache, nginx, Docker, Helm, IIS & ASP.NET Core

Every way to run it, in one place. mod_pagespeed 2.1's native module installs on Apache and nginx from the signed apt/yum repository, or runs as a Docker container fronting nginx — deploy that with Helm on Kubernetes. Windows/IIS ships from the 1.15 packaging channel, and ASP.NET Core apps get a NuGet middleware or a Linux sidecar. Each card shows which package it comes from and how it integrates.

v2.4.0 see release notes

Apache

mod_pagespeed 2.1

Native module

Prebuilt signed package from the apt/yum repository — apt-get on Debian and Ubuntu, dnf on Enterprise Linux. Drop-in replacement for the open-source build.

Debian 12/13, Ubuntu 22.04/24.04 (amd64 + arm64); RHEL/AlmaLinux/Rocky 9 (x86_64 + aarch64) & 10 (x86_64); Apache 2.4+.

Repo setup guide

nginx

mod_pagespeed 2.1

Native module

Prebuilt signed dynamic module from the apt/yum repository, pinned to each distro's stock nginx. Loads alongside your existing nginx binary — no rebuild, no traffic detour.

Debian 12/13, Ubuntu 22.04/24.04 (amd64 + arm64); RHEL/AlmaLinux/Rocky 9 (x86_64 + aarch64) via dnf, EL10 (x86_64). Each module is pinned to its distro's exact stock nginx — running a different nginx version? Contact us for a matching build.

Repo setup guide

nginx (Docker)

mod_pagespeed 2.1

Reverse proxy

Run the mod_pagespeed 2.1 worker as a Docker container in front of nginx. Same optimization pipeline, zero changes to your nginx binary or config.

Any host with Docker 24+ (Linux, macOS, Windows). Images: ghcr.io/we-amp/pagespeed-nginx:2.4.0 and ghcr.io/we-amp/pagespeed-worker:2.4.0.

Install guide

Helm

mod_pagespeed 2.1

Kubernetes

Official Helm chart deploys nginx and the worker as a two-container pod, sharing a Cyclone cache volume. Pulls the public images directly — no registry credentials required.

Kubernetes 1.28+, Helm 3.12+. Chart: pagespeed (https://modpagespeed.com/charts).

Helm guide

IIS

mod_pagespeed 1.15

Native module

MSI installer for Windows Server. Enable in IIS Manager, iisreset, and the optimization pipeline is live.

Running IISpeed? Uninstall it first — both modules cannot coexist on the same host.

Windows Server 2019 or later, IIS 10+, x64

Install guide

ASP.NET Core

mod_pagespeed 2.1

NuGet middleware

Two lines in Program.cs add the optimization pipeline to any ASP.NET Core app. Runs in-process — no sidecar, no Docker.

.NET 8 or .NET 10 on Windows, Linux, or macOS.

Install guide

ASP.NET Core Sidecar

mod_pagespeed 1.15

NuGet · Linux

WeAmp.PageSpeed.Sidecar adds the 1.15 module to your Kestrel app via middleware, with a bundled nginx optimizer on loopback behind it. One dotnet add package pulls the native binaries.

Now GA. Want the classic 1.x nginx-module behavior under .NET? Start here.

.NET 8 or .NET 10 on Linux (linux-x64, linux-arm64).

Sidecar guide

Also available: the Envoy HTTP filter (experimental, built from source) and the WordPress plugin.

The Apache and nginx packages keep their existing 1.15-line names — your apt/dnf upgrades them in place, no rename needed.

Direct downloads

The supported way to install is the signed package repositories; for IIS, download the Windows installer and follow the install guide. The worker packages (deb, rpm and Windows zip, with a checksum list) of every release are on the project's release listing. The signing key for the repositories is documented on the apt/yum page, and the public key is available as the GPG signing key.
