License FAQ

Can I use Gleipnir for free?

Yes, for non-commercial use. That includes personal projects, homelabs, education, research, and evaluation, running it on your own machine to see whether it fits your workflow.

Can I evaluate it at work?

Yes. Evaluation is non-commercial use under BUSL-1.1. You can run Gleipnir inside your company to see if it works for your team without needing a commercial license.

What counts as "commercial use"?

Production use as part of a paid product, a hosted service, or a revenue-generating workload. Internal tools at a for-profit company can be a gray area depending on context. If you're unsure where your use falls, email hello@gleipnir.dev and we'll work it out together.

Can I fork or modify the source?

Yes. The source is public; you can read it, change it, and run your modified version. Redistributions keep the same BUSL-1.1 terms. You can't relicense a fork as MIT or Apache, and you can't strip the non-commercial restriction. The Change Date and conditions travel with the code.

When does each release become Apache 2.0?

Each release of Gleipnir converts to Apache 2.0 two years after that release ships. The conversion is per-release, not project-wide: v1.0 becomes Apache 2.0 two years after v1.0 was published, v1.1 two years after v1.1, and so on.

Can I buy a commercial license now?

Yes. Email hello@gleipnir.dev with a short note about how you want to use it and we'll send you terms.
