Why is Claude Code open source but not free?

Great question — there's an important distinction here that trips a lot of people up.
The CLI tool vs. the AI model are two different things.
Claude Code, the terminal tool, is open source — you can inspect, fork, and modify the code on GitHub. But it's essentially just a shell around Claude, the AI model. And the model is what costs money, because every message you send gets processed on Anthropic's servers using significant compute.
Think of it like this: a free web browser (open source tool) that connects to a paid streaming service (the AI). The browser being free doesn't make the content free.

What are your options if you don't want to pay?

Use the API directly — pay per token instead of a flat subscription (cheaper for light usage)
Open source alternatives — tools like OpenCode or Goose let you plug in any model, including free/local ones via Ollama
Claude for Open Source program — Anthropic offers eligible OSS maintainers and contributors Claude Max free for 6 months. MacPaw You can apply at https://claude.com/contact-sales/claude-for-oss

So the short answer: the wrapper is open source, but the AI powering it isn't, and that's where the cost lives.
