Source license — roadmap
ModPageSpeed 2.0 is distributed today as a commercial subscription. We plan to publish the source under an open license; the sections below lay out the terms and timing. The binding commercial terms live in the Terms of Service.
The plan
We intend to publish the ModPageSpeed 2.0 source under the Business Source License 1.1 (BSL). Each published release will carry a four-year change-date after which that release converts automatically to Apache 2.0. The change-date is the worst-case ceiling, not a conditional — it applies regardless of We-Amp B.V.’s corporate status.
The optimization libraries inherited from the original mod_pagespeed remain Apache 2.0 today and are not affected by the BSL plan.
When
No date is committed. We’ll announce on the blog when source publication is scheduled. Enterprise customers who need source access on a defined timeline should email enterprise@modpagespeed.com.
What you get today
A signed binary distribution — Docker images, .deb/.rpm/.msi packages, and a NuGet
package for ASP.NET Core. License governed by the Terms of Service. A paid subscription includes security patches, version upgrades, and email support.
You can install and run ModPageSpeed 2.0 unlicensed to evaluate it — it fully
optimizes and adds an X-PageSpeed-Warn: unlicensed header until a license is applied. A commercial license is required for production use; manage
licensing from the admin console at /pagespeed_global_admin.
License-grant continuity
License grants survive corporate changes. If We-Amp B.V. is acquired, merged, reorganized, or wound down, paid licenses remain in force under the same terms. Once we publish source under BSL, the four-year change-date will apply regardless of We-Amp’s corporate status.
How BSL will compare
For reference, once source publication ships under BSL 1.1, this is how the model compares to typical alternatives:
| BSL 1.1 (planned) | Proprietary | AGPL | MIT | |
|---|---|---|---|---|
| Source publication | Planned | No | Yes | Yes |
| Production use | Paid subscription | Paid | Free (with conditions) | Free |
| Becomes open source | Each release after 4 years | Never | Already | Already |
