Open-source game engine Godot blocks AI agents and vibe coding

The Godot Foundation has updated its contribution guidelines to strictly ban AI-authored code and pull requests generated by automated agents. Announced in early July 2026, the decision follows an overwhelming surge of low-quality submissions that have severely burdened the open-source game engine’s volunteer maintainers.

The engine, heavily favoured by independent developers for video games like Slay the Spire 2 and increasingly utilised for virtual tabletop tools in roleplaying games, now requires all substantive code to be human-authored. Additionally, contributors must ensure that human-to-human communication on the GitHub repository remains free of AI-generated text, with the only exception being necessary machine translations. New contributors, defined as those with three or fewer merged pull requests, must now secure explicit permission from maintainers before submitting new features or significant code refactoring.

The core issue stems from contributors using artificial intelligence tools without understanding the underlying mechanics, leaving them unable to address review feedback or fix their own submissions.

Under the updated policy, AI assistance is restricted solely to menial tasks, such as code completion, regex, or find-and-replace functions. Any use of artificial intelligence in this limited capacity must be explicitly disclosed by the contributor during the pull request discussion. Automated agents and “vibe-coded” submissions will continue to result in an automatic ban from the team’s repository.

This strict stance establishes Godot as one of the first major open-source projects to formally prohibit substantial AI-generated contributions. The community response has been largely positive, with independent developers expressing relief that the engine is prioritising the well-being of its volunteer workforce over the unchecked integration of generative tools.
