Creating a New Addon Project

You can start development with a simple addon, along with a structure that includes tests and CI already set up.

1. Go to File > New Project
2. Select Blender addon from the generator list on the left.
3. Configure your project location and click Create.

This generates a clean project structure compliant with Blender 4.2+ Extensions:

• my_addon_package/: The addon’s Python package. A package with the name you entered in the wizard will be created.
• tests/: A ready-to-run test suite.
• .github/: CI workflows for GitHub Actions.
• LICENSE: A GPLv3 license file.
• pyproject.toml: Python tooling configuration.
