mod_pagespeed, maintained again.
Google released its final version of mod_pagespeed in 2020. We-Amp picked it up. mod_pagespeed 1.1 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 / 2022 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.

mod_pagespeed 1.1 is distributed under the Business Source License 1.1. The first 14 days are a free trial — full features, automatic expiration. 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 1.1 line, alongside a ground-up rewrite, ModPageSpeed 2.0.
