mod_pagespeed, maintained again.
Google released its final version of mod_pagespeed in 2020. We-Amp picked it up. mod_pagespeed 1.15 is the maintained continuation of the original open-source module — a drop-in replacement with the same configuration, the same filters, and the same behavior, plus ongoing security patches, the new Cyclone Cache, and direct support from the people who know the codebase best.
The project is led by Otto van der Schaaf, Apache PageSpeed committer and IPMC member, with 360+ pull requests across the upstream codebase.

- Drop-in replacement. Same configuration directives, same filters, same
mod_pagespeed.sosemantics. Your existing config keeps working. - Security patches for known CVEs that accumulated against the archived upstream.
- Cyclone Cache — a new C++23 lock-free shared-memory cache that replaces the legacy file cache. No tuning required; warm-up is automatic.
- First-class IIS — native module for Windows Server 2019+ (IIS 10+, 64-bit only) with
.msiinstaller. - Modern build — Bazel-based, pre-built binaries for Debian/Ubuntu (amd64 + arm64), RHEL-family (x86_64 + aarch64), and Windows.
- Direct maintainer support included with every license.
| Platform | Status | Packages |
|---|---|---|
| Apache (amd64 + arm64) | GA | .deb, .rpm, .so |
| nginx (amd64 + arm64) | GA | signed apt/yum dynamic module nginx-module-pagespeed (.deb, .rpm) |
| IIS (Windows Server 2019+) | GA | .msi |
| Envoy | Experimental | experimental HTTP filter |
The nginx dynamic module ships prebuilt and signed for Debian 11/12/13 and Ubuntu 22.04/24.04 (amd64 + arm64), each pinned to that distribution's stock nginx version. Install via the signed apt/yum repository at packages.modpagespeed.com. The Envoy HTTP filter is experimental — contact us for setup guidance.
This repository exists as a public landing point for the mod_pagespeed project under We-Amp's stewardship. Active development happens in a separate repository; all downloads, documentation, and support are at modpagespeed.com.
For issues or questions about a running deployment, please contact the maintainer — that's the fastest path to a response.
mod_pagespeed 1.15 is distributed under the Business Source License 1.1. Source publication is planned, with no date committed. You can install and run the module unlicensed to evaluate it — it fully optimizes and simply adds an X-PageSpeed-Warn: unlicensed response header (plus an admin-console notice and a startup-log warning). A commercial license is required for production use. See pricing for license details.
mod_pagespeed was created at Google in 2010 and powered web performance optimization across hundreds of thousands of sites. After Google archived the project, We-Amp B.V. — a Dutch company founded by the former maintainer — continued active development under the mod_pagespeed 1.15 line, alongside a ground-up rewrite, ModPageSpeed 2.0.
