License
Harblet is licensed under the Business Source License 1.1. It is source-available, not open source.
What's free
Production use is free as long as both of these hold:
- All production installs of Harblet operated by or for your organization together manage no more than one server.
- You don't offer Harblet to others as a hosted or managed service.
Non-production use, such as testing and development, is free on any number of servers. You may also copy, modify and redistribute the code.
What counts as a server
A server is any physical or virtual machine that Harblet manages or deploys workloads to, including the machine Harblet runs on. An install with a second server therefore manages two servers.
What counts as offering Harblet to others
Offering Harblet to others means making it available to third parties so that they can deploy or manage their own applications with it.
- Hosting your own applications with Harblet is not offering it to others, no matter who uses those applications.
- Contractors and service providers who work on your behalf are not third parties.
- Your organization includes all of your affiliates under common control.
More servers
For more than one server, write to mail@harblet.com about a commercial license.
