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

Software license

mod_pagespeed 2.1 is open source under the Apache License 2.0 (Apache-2.0) — the same license the original mod_pagespeed codebase carried. Every feature is available to everyone, in development and in production. The commercial terms for a support subscription live in the Terms of Service.

The license

The web-server module and the optimizer worker are licensed under the Apache License 2.0; bundled third-party components are listed in THIRD-PARTY-NOTICES under their own licenses. The LICENSE, NOTICE and THIRD-PARTY-NOTICES files ship with every distribution — the signed .deb and .rpm packages, the Docker images, and the NuGet packages. The source is published; you are free to build, modify, and redistribute it under the same terms.

What We-Amp sells

Support — and hardened builds. The software is the same for everyone and the standard signed packages are free; support plans and hardened, attested builds from the people who build it are what’s for sale. Support subscriptions are governed by the Terms of Service; the support terms live at we-amp.com/licensing/.

Predecessor lines

The predecessor lines carry the Apache License 2.0 as well. Running ModPageSpeed 2.0? See the migration guide. Running mod_pagespeed 1.15? See the guide to upgrading to mod_pagespeed 2.1.

Continuity

The Apache License 2.0 is a perpetual grant that does not depend on We-Amp B.V.’s corporate status. If the company is acquired, merged, reorganized, or wound down, the license you hold stays in force, and support subscriptions remain governed by the same Terms of Service.
