Nova vs crw

Nova: Nova is a Rust-native implementation of "computer use" capability for LLM agents, enabling AX-first control over macOS and Windows through semantic UI interactions, screenshots, OCR, and various input methods. It acts as a Model Context Protocol server, offering robust and direct system-level automation without relying on Python/JS stacks.; crw: fastCRW is a high-performance engine designed to transform URLs into clean markdown or structured JSON. It provides a unified solution for web searching, scraping, mapping, crawling, and data extraction, available as a local Rust binary or a managed API.
