Spider
Rust-based AI-friendly crawler cloud: URL in, clean markdown or structured JSON out.
About
Spider (spider.cloud) is a Rust-based web scraping and crawling cloud positioned for AI agents and LLMs. Point it at a URL and get back clean markdown, structured JSON via natural-language extraction prompts, screenshots, or links, with anti-bot bypass, residential proxies, headless browsers, and native integrations for MCP, LangChain, LlamaIndex, CrewAI, and AutoGen.
Its AI endpoints accept a prompt plus an optional extraction schema, so a single request returns structured data shaped to your needs. The open-source spider-rs crate powers the core crawler with Rust, Node.js, Python, and CLI clients, plus a dedicated spider_mcp package.
Limitations: credit-based cloud pricing needs budget care at scale; heavily interactive single-page apps can still challenge automated extraction, and AI extraction params are billed separately from base crawling.
What it can do
- AI-guided crawl, scrape, search, and browser automation endpoints
