Anthropic's Claude for Open Source program gives qualifying developers six months of Claude Max 20x, the top consumer plan. You apply yourself. Here's who qualifies, how to apply, and what happens when the six months end.
Who qualifies
You need to fit any one of these:
- Maintainer or library author: 500+ dependent repos, 100+ dependent packages, or 200,000+ combined monthly downloads across registries like npm, PyPI, crates.io or RubyGems.
- Core contributor: a listed committer or maintainer on a recognized foundation or language project, such as CPython, the Linux kernel or Kubernetes.
- Active contributor: 100+ pull requests merged into repos you don't own in the last 12 months.
- Community builder: one of your repos has 20+ unique external contributors with merged pull requests in the last 12 months.
- Critical infrastructure: a repo you maintain has an OpenSSF criticality score of 0.4 or higher.
If you don't fit any of these, the page says to apply anyway and tell Anthropic about your work.
