Cons
- -Active development with frequent updates suggests ongoing stability issues that may require regular maintenance
- -Complex feature set may be overkill for simple web scraping needs that don't require LLM optimization
- -Cloud API still in closed beta with limited availability, requiring application for early access
- -Repository is still in development and not fully ready for self-hosted deployment
- -API-based service likely requires subscription pricing for production use
- -As a relatively new tool, long-term stability and support ecosystem may be uncertain
