Mastra's License is Elastic License 2.0 (ELv2) - Commercial Use Considerations and OSS License Comparison
As stated in the Mastra official documentation, Mastra’s license is Elastic License 2.0 (ELv2).
Elastic License 2.0 is not an Open Source License defined by OSI (Open Source Initiative). Therefore, when using Mastra for commercial purposes, you need to carefully review the terms of Elastic License 2.0 and comply with the usage conditions.
For details about Elastic License 2.0, please check the official documentation.
In contrast, the following OSS (Open Source Software) are all provided under the MIT License, which is widely used among Open Source Licenses.
When selecting OSS, it’s important to understand the types of licenses and the terms that each license defines. Especially when considering commercial use, careful attention is needed as usage conditions and restrictions can vary significantly depending on license differences.
When considering using Mastra, it’s advisable to understand that it uses Elastic License 2.0, compare it with OSS licensed software, and make a choice that fits your project requirements.
That’s all from the Gemba.
