Yes, you can use and customize Airbyte source code for personal use. Airbyte Core is licensed under the Elastic License v2 (ELv2), which allows you to modify the source code. However, there are some limitations you should be aware of: 1.
You cannot provide the products to others as a managed service. For example, you cannot sell a cloud service that provides users with direct access to Airbyte. You can, however, sell access to applications built and run using Airbyte. 2.
You cannot circumvent the license key functionality or remove/obscure features protected by license keys. For example, you cannot remove or change watermarks or keys to unlock proprietary functionality. For more details, you can refer to the [License FAQ](
https://docs.airbyte.com/developer-guides/licenses/license-faq#what-limitations-does-elv2-impose-on-my-use-of-airbyte). Additionally, if you are interested in developing your own connectors, you can do so as part of Airbyte Open-Source deployments. Custom connectors are currently exclusive to Airbyte Open-Source, but there are plans for their release on Airbyte Cloud in January 2024. You can track the progress on this development [here](
https://github.com/orgs/airbytehq/projects/37?pane=issue&itemId=45471174). For guidance on building new connectors, you can check out the [contributing guide on building connectors](
https://docs.airbyte.com/contributing-to-airbyte/). If you have any further questions or need assistance, feel free to reach out to the Airbyte community or support team. Sources: - [License FAQ](
