mod_pagespeed 2.1 is here — open source (Apache-2.0): the module you know, plus the optimizer worker

Alternatives to mod_pagespeed, ngx_pagespeed, and IISpeed

mod_pagespeed and ngx_pagespeed are deprecated. IISpeed is in transition. These pages cover the actively-maintained continuation, mod_pagespeed 2.1, and how each server reaches it.

mod_pagespeed 2.1 shares the optimization core that powers 230,000+ live sites today (BuiltWith, May 2026) — not We-Amp customers, but proof it works at scale.
