### 5. GitHub prompt collections

- **URL:** https://github.com/search?q=awesome+prompts&type=repositories

- **Best for:** API prompt patterns
- **Price:** Free docs

Best official examples for API patterns and model behavior, but not a broad consumer prompt library.

## Honourable mentions

- **PromptBase:** Useful marketplace, but not primarily a free prompt library.
- **Reddit prompt threads:** Great raw examples; poor retrieval, ownership and update structure.
