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; Priority and Enterprise add a private package repository (being set up). The software is the same for everyone and the standard signed packages are free; support plans 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.
