Bottom line: Ladybird blocks public code contributions because AI tools have made the former trust heuristic (effort as an indicator of good faith) obsolete.
The open-source project Ladybird will no longer accept public pull requests and is closing all open requests in the queue. The reason is concern about AI-generated code contributions that threaten established trust models.
The development team of the independent web browser Ladybird announced on June 5, 2026 that it will no longer accept public pull requests. All future code changes will be submitted exclusively by clearly defined project maintainers. Already open public pull requests will be closed to completely prevent this contribution path.
The project cites AI as the reason: “A pull request no longer tells us as much as it used to about the person who submits it. A substantial patch used to represent significant effort, and that effort was a reasonable indicator of good faith. This assumption no longer holds.” The team has observed that well-organized and well-resourced campaigns in the open-source sector deliberately attempt to gain the trust of code maintainers in order to abuse it later. AI tools massively accelerate and cheapen the creation of superficially credible code contributions.
Paradoxically, Ladybird itself used AI assistants for internal development in February 2026. The project deployed Claude Code and Codex to port the JavaScript engine LibJS to Rust. In doing so, the developers used hundreds of small, precisely formulated prompts to control the AI system. The porting process for approximately 25,000 lines of Rust code was completed in two weeks – a task that would have required a human developer several months.
The project emphasizes that with the transition to a production-ready browser for end users, clear accountability for every line of code is required. What matters is not the origin of the code, but the defined liability for consequences after integration. To prevent an uncontrolled shadow contribution system through alternative channels, there will also be no separate process for code patches via issues, comments, emails, or forks.
External contributions remain possible in other areas: precise bug reports and their minimization, compatibility testing, discussions about web standards and design questions, and security reports. The source code remains publicly accessible and available under the appropriate license.
