Yes, OpenJDK is free for commercial use, and so are several production ready distributions built from it. The real question is who provides your updates and support, and that is a usage decision, not a per employee one.
The short answer
OpenJDK is free and open source, and you can use it commercially in production without a per employee bill. Several distributions built directly from OpenJDK are also free for commercial use and are patched on a regular cadence. The confusion usually comes from conflating the free runtime with paid support, and from Oracle messaging that blurs the line. For the full context, see the OpenJDK migration playbook pillar.
What free actually covers
Free means you can download, install, run, and redistribute the runtime in commercial production at no license cost, and receive security updates from the distribution provider on its public schedule. It does not come with a vendor support contract or guaranteed response times unless you buy those separately. For a great many enterprise workloads the free runtime with public updates is entirely sufficient, which is exactly why it threatens the per employee model.
Free runtime versus paid support
| Option | Cost basis | Good fit for |
|---|---|---|
| Free OpenJDK distribution | No license cost, public updates | Most standard server and internal workloads |
| Commercial OpenJDK support | Priced on usage, not employees | Critical systems needing guaranteed response |
| Oracle Java SE | Per employee Universal Subscription | The rare workload that requires it |
The key contrast is the cost basis. Even paid OpenJDK support is tied to what you run, not to a headcount that counts contractors and temporary workers who never touch Java.
Why this matters against the employee metric
Since January 2023 Oracle Java SE has been priced per employee at 5.25 to 15.00 dollars per month, counting every full time and part time employee, every contractor, and every temporary worker regardless of use. A free or usage based OpenJDK alternative removes that arithmetic entirely. For most estates the difference is not a small saving, it is the elimination of the largest line item in the Java bill. How the two runtimes compare under the hood is covered in OpenJDK versus Oracle Java SE: the real differences.
Reading the fine print
Free does not mean unmanaged. You still own the responsibility to patch on schedule, to track which distribution and version each workload runs, and to keep that inventory current. Good housekeeping here is also your audit defense, since LMS audits intensified in 2026 with a three year lookback. Treat the free runtime as a supported part of your estate with a clear update owner, not as something you install and forget.
Free still needs a migration plan
The runtime being free does not make the move automatic. You still inventory the estate, test each workload, and cut over with a rollback path. The savings are real but they follow a disciplined migration, not a flip of a switch. The safe sequence is set out in how to migrate off Oracle Java safely.
The buyer side takeaway
OpenJDK is free for commercial use, and free distributions cover most enterprise workloads. Where you want guaranteed support, buy it on a usage basis rather than per employee. Either path removes the headcount arithmetic that makes Oracle Java expensive. Inventory, test, and migrate with discipline to capture the saving. Download the field guide below to start.
