Summary

Anthropic is now providing its Claude Max 20x plan, typically priced at $200 per month, for free to eligible open source maintainers for a six-month period. To qualify, maintainers must be a primary or core team member of a public GitHub repository with over 5,000 stars or an NPM package with more than 1 million monthly downloads. Applicants must also have demonstrated recent activity, such as commits, releases, or pull request reviews, within the last three months. Anthropic encourages maintainers of critical, widely depended-upon projects that might not strictly meet the star/download criteria to apply. Applications are reviewed on a rolling basis, with a cap of 10,000 accepted contributors.

Key takeaway

For open source maintainers managing projects with significant community reliance, you should evaluate if your project meets Anthropic's criteria for free Claude Max access. Applying could provide valuable AI resources for development and maintenance tasks, potentially enhancing project efficiency and contributor experience for six months. Ensure your recent contribution history is verifiable.
