mod_pagespeed 1.1
mod_pagespeed, maintained again.
Google released its final release of mod_pagespeed in 2020. We picked it up. mod_pagespeed 1.1 is a drop-in replacement — same config, same filters, same behavior — with ongoing security patches, the new Cyclone Cache, and support from the people who know the codebase best.
Four web servers. One optimized codebase.
mod_pagespeed 1.1 runs natively on every major web server — not as a proxy, not as a sidecar, but as a first-class module.
nginx
Dynamic module for nginx 1.26+
Apache
Drop-in replacement for the Google module
IIS
Native Windows Server support
Envoy
HTTP filter for Envoy proxy
What's changed since Google's last release
We picked up where Google left off and got to work. Everything below ships in 1.1.
Maintained and supported
Regular updates, security patches, and direct support from the team that knows the codebase best.
Drop-in replacement
Same configuration directives, same filters, same behavior. Swap the binary and you're done.
Cyclone Cache
New cache backend shared with ModPageSpeed 2.0. Fixed-size file, lock-free reads, memory-mapped I/O.
Modern build system
Rebuilt with Bazel for reproducible builds. Pre-built binaries for major platforms — no more compiling from source.
Security fixes
All known CVEs from the open-source project patched. Ongoing security maintenance included.
Multi-platform
One codebase, four web servers. nginx, Apache, IIS, and Envoy — all first-class targets.
Two products. Both maintained.
Both products are actively maintained. Pick the one that fits your situation.
