The PageSpeed Modules, mod_pagespeed and ngx_pagespeed, are open-source webserver modules that optimize your site automatically.

Disclaimer: Apache PageSpeed is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

Other PageSpeed integrations

While mod_pagespeed (Apache) and ngx_pagesped (Nginx) are the only two server integrations developed by the core PageSpeed team, people have ported PageSpeed to other servers as well.
