CLI · Headless workflow

Unity editor command line

Unity’s editor command line supports batch-mode automation and project-specific methods.

Platforms: Windows, macOS, Linux

Claude Code · Not documented

The native interface is documented, but no setup for this coding agent is established by this source.

Codex · Not documented

The native interface is documented, but no setup for this coding agent is established by this source.

Cursor · Not documented

The native interface is documented, but no setup for this coding agent is established by this source.

Requirements and limitations

A compatible Unity Editor installation, project and any C# methods invoked through executeMethod.

Build workflows depend on project scripts and installed modules; batch mode is distinct from controlling a live session.

Questions before setup

Does one integration cover every workflow?

No such claim is made. Check the capability list, requirements and limitations of each route, then test a copy of a representative project.
