Frequently Asked Questions

How are http4k Pro modules different from the http4k Community modules?

Pro modules are commercially licensed extensions developed specifically to solve common enterprise use cases. They are distributed under org.http4k.pro Maven coordinate group. You can find details of the http4k Commercial License here.

Does this mean the Pro modules are more reliable than http4k Community?

No. All http4k modules share the same high quality standards and testing rigor. Pro modules provide additional enterprise-focused features rather than enhanced reliability.

How are the modules licensed?

Pro modules are licensed annually per floating developer seat for both development and production use, meaning multiple developers can use the modules but only one developer per seat at a time. Licenses include access to Maven artifacts via Maven Central and technical support via GitHub issues.

My organisation wishes to use several of the http4k Pro modules. Can we buy a bundle of licenses?

Yes. We offer volume discounts for organisations that wish to purchase multiple Pro modules. Please contact us using the button below.

Can I use Pro modules for free?

We are completely supportive of experimentation with http4k technologies, so Pro modules are free for personal use, non-profit organizations, non-commercial research, and qualifying small businesses. See our commercial license for exact terms.
