License

Data Relay Control is source available, not open source. Current distributions are licensed under the Data Relay Source Available License 1.0, except where a specific file or third-party component states a different license.
The full license text in the datarelay-labs/gdc-platform LICENSE file is controlling. This page is a plain-language summary and does not replace the license terms.

Free and permitted use

You may use Data Relay Control free of charge for:
  • personal use
  • education and non-commercial research
  • evaluation and testing
  • internal commercial use
  • internal source-code modification for permitted uses
  • customer-owned deployments where the customer directly controls and uses the deployment
  • paid installation, integration, migration, maintenance, training, or support for a customer-owned deployment, provided Data Relay itself is not resold or operated as a managed service

Productization is not permitted

Without a separate written commercial license from Data Relay Labs, you may not:
  • resell or sublicense Data Relay
  • commercially redistribute the original or a modified version as a standalone product
  • OEM, embed, bundle, or integrate Data Relay or substantial portions of its source code into a commercial product or appliance
  • white-label, rename, rebrand, or fork Data Relay for commercial productization
  • operate or offer Data Relay functionality as SaaS, MSP, hosted, shared, or multi-tenant service for third parties
  • use Data Relay or a substantial portion of its source code to create, improve, or maintain a competing or substantially similar product or service
  • remove or obscure copyright, license, attribution, or trademark notices
  • describe the project as OSI-approved open-source software

Examples

Separate commercial license

Resale, OEM/embedding, white-labeling, commercial redistribution, derivative commercial products, SaaS/MSP/hosted offerings, competitive-product rights, or other productization may be permitted only under a separate written commercial license granted by Data Relay Labs.

Why it is called source available

The license places restrictions on productization, competing products, and SaaS/MSP use. Because those use restrictions are not compatible with the OSI Open Source Definition, Data Relay Control is described as source available, not open source.
