OpenMetadata vs spider

OpenMetadata: OpenMetadata is a unified metadata platform for data discovery, observability, and governance, powered by a central repository and column-level lineage. It's a fast-growing open-source project that enables end-to-end metadata management across diverse data services.; spider: Spider is a concurrency-first crawling engine in Rust. It fetches over HTTP first and launches headless Chrome only for pages that need JavaScript, streams pages as they arrive, and scales from one script to a distributed worker fleet with the same API. It is available as a Rust crate, CLI, Node.js and Python packages and an MCP server, and the same engine powers the paid Spider Cloud service.
