spider vs thunderbit-mcp-server

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.; thunderbit-mcp-server: Thunderbit MCP Server is an open-source toolkit for the Thunderbit Open API that ships three packages: a CLI for scripted extraction, an MCP server exposing seven scraping and distillation tools, and a Claude Code plugin. It converts any web page to clean LLM-ready Markdown, extracts structured data via JSON Schema, and supports batch processing — all backed by a free API key.
